Horizontal transfer of Wolbachia between phylogenetically distant insect species by a naturally occurring mechanism. (1/879)

Wolbachia is a genus of alpha-proteobacteria found in obligate intracellular association with a wide variety of arthropods, including an estimated 10-20% of all insect species [1]. Wolbachia represents one of a number of recently identified 'reproductive parasites' [2] which manipulate the reproduction of their hosts in ways that enhance their own transmission [3] [4] [5] [6] [7] [8] [9]. The influence of Wolbachia infection on the dynamics of host populations has focused considerable interest on its possible role in speciation through reproductive isolation [3] [10] [11] and as an agent of biological control [2] [12] [13]. Although Wolbachia normally undergoes vertical transmission through the maternal line of its host population [14], there is compelling evidence from molecular phylogenies that extensive horizontal (intertaxon) transmission must have occurred [1] [9] [15] [16] [17]. Some of the best candidate vectors for the horizontal transmission of Wolbachia are insect parasitoids [15], which comprise around 25% of all insect species and attack arthropods from an enormous range of taxa [18]. In this study, we used both fluorescence microscopy and PCR amplification with Wolbachia-specific primers to show that Wolbachia can be transmitted to a parasitic wasp (Leptopilina boulardi) from its infected host (Drosophila simulans) and subsequently undergo diminishing vertical transmission in this novel host species. These results are, to our knowledge, the first to reveal a natural horizontal transfer route for Wolbachia between phylogenetically distant insect species.  (+info)

Genetic localization of a Drosophila melanogaster resistance gene to a parasitoid wasp and physical mapping of the region. (2/879)

Drosophila melanogaster larvae usually react against eggs of the parasitoid wasp Leptopilina boulardi by surrounding them with a multicellular melanotic capsule. The genetic determinism of this response has been studied previously using susceptible (non-capsule-forming) and resistant (capsule-forming) strains. The results suggest that differences in their encapsulation response involve a single gene, resistance to Leptopilina boulardi (Rlb), with two alleles, the resistant one being dominant. Rlb confers specific protection against Leptopilina boulardi and is thus probably involved in parasitoid recognition. Recent studies have localized this gene on the right arm of the second chromosome and our aim was to precisely determine its genetic and molecular location. Using strains bearing deletions, we demonstrated that resistance to Leptopilina boulardi is conferred by the 55C; 55F3 region and that the 55E2-E6; F3 region is particularly involved. A physical map of the 55C; 56A region was then constructed, based on a set of overlapping cosmid and P1 phage clones. Using single and double digests, cross hybridization of restriction fragments, and location of genetically mapped genes and STSs, a complete, five-enzyme restriction map of this 830-kb region was obtained.  (+info)

Developmental analysis of Ganaspis xanthopoda, a larval parasitoid of Drosophila melanogaster. (3/879)

Ganaspis xanthopoda is a solitary larval parasitoid wasp of the fruit fly Drosophila melanogaster. The life cycle of Ganaspis xanthopoda in the wild-type and developmental mutant ecdysoneless strains of Drosophila melanogaster is described. The female infects a second-instar host larva. The parasitoid embryo hatches into a mobile first-instar (L1) larva. The L1 parasitoid has fleshy appendages and, while mobile, it remains confined within the wandering larval host. The second-instar larva (L2) is an endoparasite within the host prepupa and lacks appendages. The L2-to-L3 molt is dependent on pupation and marks the transition of the endoparasite into an ectoparasite. The third-instar larva (L3) is a sessile ectoparasite, develops an extensive tracheal system and consumes the host as it progresses through its prepupal and pupal stages. A single adult male or female emerges from the host puparium. The developmental analysis of Ganaspis xanthopoda reveals a tight synchrony between host and parasitoid development which is, at least in part, dependent on the ecdysone levels of the host.  (+info)

Mapping of hybrid incompatibility loci in Nasonia. (4/879)

According to theory, F(2) hybrid breakdown (lethality or sterility) is due to incompatibilities between interacting genes of the different species (i.e., the breaking up of coadapted gene complexes). Detection of such incompatibilities is particularly straightforward in haplodiploid species, because virgin F(1) hybrid females will produce haploid recombinant F(2) males. This feature allows for screening of the complete genome for recessive genetic incompatibilities. Crosses were performed between Nasonia vitripennis (v) and its sibling species N. giraulti (g). First, a linkage map was produced using RAPD markers. RAPD markers showed an overall bias toward vitripennis alleles, a pattern not predicted by the basic two-interactor Dobzhansky-Muller model. Recovery patterns of visible markers were consistent with those of linked RAPD markers. If particular genetic interactions between two loci are causing hybrid lethality, then those genotypes should be underrepresented or absent among adult F(2) males. Four sets of significant incompatibilities were detected by performing pairwise comparisons of markers on different chromosomes. Likely explanations for the observed patterns are maternal effect-zygotic gene incompatibilities or clustering of incompatibility loci. Due to the short generation time, advantages of haplodiploidy, and availability of markers, Nasonia promises to be a productive system for investigating the genetics of hybrid inviability.  (+info)

Genetic support for the evolutionary theory of reproductive transactions in social wasps. (5/879)

Recent evolutionary models of reproductive partitioning within animal societies (known as 'optimal skew', 'concessions' or 'transactional' models) predict that a dominant individual will often yield some fraction of the group's reproduction to a subordinate as an incentive to stay in the group and help rear the dominant's offspring. These models quantitatively predict how the magnitude of the subordinate's 'staying incentive' will vary with the genetic relatedness between dominant and subordinate, the overall expected group output and the subordinate's expected output if it breeds solitarily. We report that these predictions accord remarkably well with the observed reproductive partitioning between conesting dominant and subordinate queens in the social paper wasp Polistes fuscatus. In particular, the theory correctly predicts that (i) the dominant's share of reproduction, i.e. the skew, increases as the colony cycle progresses and (ii) the skew is positively associated both with the colony's productivity and with the relatedness between dominant and subordinate. Moreover, aggression between foundresses positively correlated with the skew, as predicted by transactional but not alternative tug-of-war models of societal evolution. Thus, our results provide the strongest (quantitative support yet for a unifying model of social evolution.  (+info)

Glucosinolate genetics and the attraction of the aphid parasitoid Diaeretiella rapae to Brassica. (6/879)

The control of insect pests using parasitoids and carnivores has been successfully applied in protected cropping systems, orchards and forestry. Their success in annual field crops has been more limited due largely to the difficulties of attracting and maintaining a sufficient density of parasitoids in the crop before the levls of the insect herbivores become economically damaging. Parasitoids are known to be attracted to host-plant volatiles; thus, manipulating the host-plant chemistry may provide a means of enhancing the attraction of parasitoids to their prey. In this study we describe the differential attraction of the braconid wasp Diaeretiella rapae to two near-isogenic lines of Brassica oleracea which differ in a gene which alters the chemical structure of the isothiocyanates which are emitted following tissue damage. We demonstrate that, by enhancing the production of but-3-enyl isothiocyanate in B. oleracea and Brassica napus (oilseed rape), we can increase the attraction of D. rapae to these plants under standard field conditions.  (+info)

Estimating ancestral geographical distributions: a Gondwanan origin for aphid parasitoids? (7/879)

We tested the published hypothesis of a Gondwanan origin for the overwhelmingly northern hemisphere aphid parasitoids (Aphidiinae) as follows: (i) finding their sister group by a phylogenetic analysis of the entire Braconidae (Insecta: Hymenopterai using sequence data from approximately 500 bp fragments of both the nuclear 28S (D2 region) and mitochondrial 16S rDNA genes, (ii) using this sister-group relationship and the more informative 28S D2 gene to estimate the phylogeny of the Aphidiinae and (iii) estimating the ancestral distribution for the Aphidiinae using maximum-likelihood and maximum-parsimony methods. Both methods indicated a Gondwanan origin.  (+info)

A gene encoding a polydnavirus structural polypeptide is not encapsidated. (8/879)

Polydnaviruses are symbiotic viruses associated with some parasitic Hymenoptera that are vertically transmitted as proviruses within wasp genomes. To study this symbiotic association a gene encoding an abundant Campoletis sonorensis polydnavirus virion protein was characterized. This gene is not encapsidated but resides in the wasp genome where it is expressed only during virus replication. Immunolocalization studies detected the encoded 44-kDa protein only in oviduct tissue with ultrastructural studies detecting epitopes between or on virion envelopes. Expression and localization of the 44-kDa protein are consistent with its being a viral structural protein but localization of the gene only within the wasp genome is atypical, raising the possibility that this protein is adventitiously packaged during virion assembly. To address this possibility, quantitative dot blot and genomic Southern blot hybridizations were performed to determine whether the copy number of the p44 gene increased disproportionately during replication, as would be expected for a gene encoding a virion protein. The copy number of the p44 gene increases in tissues supporting virus replication but is unchanged in other tissues, suggesting that this gene is amplified in replicative cells. The data indicate that genes encoding polydnavirus virion proteins may be distributed between wasp and encapsidated viral genomes.  (+info)

Fine Art Photography: Yellow Paper Wasp Polistes dominulus Author: Alfred Schauhuber Date: 2006-08-21 Maximum available size: 18. DOWNLOAD
ALMOST all taxa contain species with two sexes: males and females. However, the genetic mechanisms underlying the establishment of the two sexes are quite diverse. From an evolutionary point of view, it is important to understand the genetics behind the various mechanisms. In many organisms sex determination relies on heteromorphic sex chromosomes. In mammals the presence of the Y chromosome is the primary determinant of maleness and in Drosophila the ratio of X chromosome to autosomes is the key factor for sex determination. Chromosomal sex determination also applies for birds and fish. This type of primary sex determination does not hold for the order Hymenoptera, which includes ants, bees, and wasps. These insects have a haplo-diploid sex determination system: haploid males arise from unfertilized eggs, while diploid females arise from fertilized eggs. However, diploid males and triploid females have also been reported (Whiting 1960), but never haploid females. It is unclear how this can be ...
Description: There is extraordinary diversity in sexual dimorphism (SD) among animals, but little is known about its epigenetic basis. To study the epigenetic architecture of SD in a haplodiploid system, we performed RNA-seq and whole-genome bisulfite sequencing of adult females and males from two closely related parasitoid wasps, Nasonia vitripennis and Nasonia giraulti. More than 75% of expressed genes displayed significantly sex-biased expression. As a consequence, expression profiles are more similar between species within each sex than between sexes within each species. Furthermore, extremely male- and female-biased genes are enriched for totally different functional categories: male-biased genes for key enzymes in sexpheromone synthesis and female-biased genes for genes involved in epigenetic regulation of gene expression. Remarkably, just 70 highly expressed, extremely male-biased genes account for 10% of all transcripts in adult males. Unlike expression profiles, DNA methylomes are ...
Mischocyttarus mexicanus cubicola is a neotropical paper wasp found in the New World. It is a social wasp that demonstrates two different types of nesting strategies, depending upon context. This context-dependent trait makes Mischocyttarus mexicanus cubicola a good model to study social biology within social wasps. In detail, this trait allows for the females of this species to form nests both individually and as co-founders with other females within the same colony. This subspecies is also known to exhibit cannibalism, with M. m. cubicola queens feeding on their own larvae for nourishment when unaided by workers. Mischocyttarus mexicanus cubicola is part of the Vespidae family, which classifies the species as a wasp. Wasps, including M. m. cubicola are classified under the order of Hymenoptera, making ants, bees, and sawflies, which fall under the same order, relatives of wasps. It then falls under the Polistinae subfamily, which is home to paper wasps specifically. The genus of this species, ...
Flight activity in females of the parasitoid wasp Nasonia vitripennis(Walker) was examined by measuring still-air tethered flight. There was a large amount of variation among females in flight duration. The longest single flight (with no pauses of more than 5 s) was more than 2 h long. Mating status had a significant and large effect on flight: mated females flew twice as long as virgin females. There also was a slight but significant effect of age on flight, with 3-day-old females being less likely to fly than 1-day-old females. Flight duration was not affected by prior exposure to other females, to honey, or to a low or a high host density.
Paper wasps are the paper-makers of the insect world. These social insects live together and build nests made of paper. They make their paper by chewing bits of old wood scraped from boards or woody plants and mixing it with their saliva. The wet material is patted and shaped into rows of paper cells, much like the wax cells of a bee honeycomb.. When the paper paste dries, the wasps have a strong paper nest in which to raise the young wasps. Paper wasp nests are often built to hang upside down from tree limbs or attached beneath the eaves of buildings. Their nests include numerous compartments within which wasps lay their eggs and rear their young.. The nests typically do not have an outer shell with the cells of the nest visible. In fact, it somewhat resembles an umbrella and is the reason they may be called umbrella wasps.. In North America alone, there are over 22 species of paper wasps. Paper wasps belong to the genus Polistes. Worldwide, there are over 200 species. These wasps measure 1.9 ...
The primary, solitary parasitoids Asobara tabida Nees (Braconidae: Alysiinae) and Leptopilina heterotoma (Thomson) (= Pseudeucoila bochei Weld): Eucoilidae) are sympatric, show seasonal overlap and share the same hosts, viz. larvae of Drosophila species. Discrimination between unparasitized hosts and hosts parasitized by the other species was studied. No differences were found in their behaviour towards the two kinds of hosts: these were accepted equally well for parasitization.
Paternal-Sex-Ratio (PSR) is a B chromosome that causes all-male offspring in the parasitoid wasp Nasonia vitripennis. It is only transmitted via sperm of carrier males and destroys the other paternal chromosomes during the first mitotic division of the fertilized egg. Because of haplodiploidy, the e …
Wolbachia is an endosymbiotic bacteria which is vastly distributed in arthropods and is known for its ability to manipulate the reproduction of its host to favor its own vertical transmission. In flies, Wolbachia causes a sterility syndrome known as Cytoplasmic Incompatibility (CI). CI occurs when sperm from infected males fertilize uninfected eggs. Paternal chromosomes in these eggs appear unable to properly divide during the first zygotic cycle but the molecular bases of this intriguing phenotype remain elusive. We are interested in understanding how Wolbachia interferes with the remodeling of paternal chromatin at fertilization in Drosophila, as well as in the parasitoid wasp Nasonia vitripennis.. ...
Vespula acadica, also known as the Forest Yellowjacket, is a North American species of eusocial wasp which is part of the rufa group within the genus Vespula. It is a black and yellow wasp that is found in arboreal areas and builds its nests most often in decaying vegetation like logs, but has occasionally been found to build aerial nests. Due to its preference for forests V. acadica does not normally come into contact with humans; however, when colonies are disturbed, workers of this yellowjacket may be quite aggressive and persistent and sting repeatedly. V. acadica belongs to the genus of Vespula which includes numerous species of social wasps. The wasps within the Vespula genus are found throughout the Northern Hemisphere and are commonly referred to as Yellow Jackets in North America. Vespula wasps are commonly mistaken for other genera, most often the paper wasps of the genus Polistes. V. acadica is considered to be a member of the Vespula rufa group and is most closely related to other ...
Wasp venoms constitute a molecular reservoir of new pharmacological substances such as peptides and proteins, biological property holders, many of which are yet to be identified. Exploring these sources may lead to the discovery of molecules hitherto unknown. This study describes, for the first time in hymenopteran venoms, the identification of an enzymatically inactive phospholipase A2 (PLA2) from the venom of the social wasp Polybia occidentalis. P. occidentalis venom was fractioned by molecular exclusion and reverse phase chromatography. For the biochemical characterization of the protein, 1D and 2D SDS-PAGE were performed, along with phospholipase activity assays on synthetic substrates, MALDI-TOF mass spectrometry and sequencing by Edman degradation. The protein, called PocTX, was isolated using two chromatographic steps. Based on the phospholipase activity assay, electrophoresis and mass spectrometry, the protein presented a high degree of purity, with a mass of 13,896.47 Da and a basic pI. After
Figs and fig wasps have evolved to help each other out: Fig wasps lay their eggs inside the fruit where the wasp larvae can safely develop, and in return, the wasps pollinate the figs.. But what happens when a wasp lays its eggs but fails to pollinate the fig?. The trees get even by dropping those figs to the ground, killing the baby wasps inside, reports a Cornell and Smithsonian Tropical Research Institute study published in the Proceedings of the Royal Society B: Biological Sciences (published online Jan. 13).. The findings suggest that when one species in a mutually beneficial relationship fails to hold up its end of the bargain, sanctions may be a necessary part of maintaining the relationship.. We want to know what forces maintain this 80 million-year-old mutualism between figs and their wasp pollinators, said lead author Charlotte Jandér, a Cornell graduate student in neurobiology and behavior, who conducted the study as a Smithsonian Tropical Research Institute predoctoral fellow. ...
Wasps - they are the most unwelcomed guests you can have outside your home. They sting, they swarm, and for some reason, you have a bunch of them outside your house wanting to come in. What is attracting wasps to your house? Is it your wasp-y lifestyle? Are they there for cocktail parties and hot gossip? No, probably not. Actually, definitely not. All joking aside, if you have an abundant amount of wasps around your house there might be a very preventable reason that could help you get rid of them. **What Attracts Wasps?** While wasps come in a variety of different species, all species can be placed in two classifications - solitary or social. Solitary wasps, like their name suggests, live in smaller communities, if not by themselves. These solitary wasps, like mud daubers or cicada killers, build small homes on the eaves of your building or in the dirt. Social wasps, however, live in larger communities that like secluded places that are safe to build a community. This can be in t...
Jumping is not about fun and games for insect larvae. They must do it to survive. This manoeuvre is all about finding a shady spot to develop in, according to researchers from Kyushu University in Japan, who led research into the jumping behavior of a minute parasitic wasp, published in Springers journal The Science of Nature.. The use of jumping as a means of movement has only been observed in a few species of parasitic wasp larvae, suggesting that this behavior does not easily evolve. One such wasp is the three millimeter long Bathyplectes anurus. This parasite is used as a form of biological pest control against alfalfa weevil (Hypera postica), a destructive agricultural pest that attacks legumes. Adult Bathyplectes anurus wasps lay their eggs in alfalfa weevil larvae. When the wasp larva develops, it crawls out from inside its host and promptly feeds on it. It then spends ten months in a self-spun cocoon inside the cocoon of the alfalfa weevil larva it has eaten, before developing into a ...
Its not every day that you hear about spy missions that involve a lack of sex, but clearly parasitic wasps dont pay much attention to Hollywood clichés. These insects merge the thriller, science-fiction and horror genres, They lay their eggs inside other animals, turning them into slaves and living larders that are destined to be eaten inside-out by the developing grubs. To find their victims, they perform feats of espionage worthy of any secret agent, tapping into their marks communication lines, tailing them back to their homes and infiltrating their families. Two species of parasitoid wasp - Trichogramma brassicae and Trichogramma evanescens - are particularly skilled at chemical espionage. Theyve learned to home in on sexual chemicals used by male cabbage white butterflies. After sex, a male coats the female with anti-aphrodisiac that turns off other suitors and protects the males sexual investment. These chemicals are signals from one male to another that say, Buzz off, shes taken. ...
TY - JOUR. T1 - Linking the coevolutionary and population dynamics of host-parasitoid interactions. AU - Fellowes, M D E AU - Travis, J M J PY - 2000/8. Y1 - 2000/8. N2 - The interplay between coevolutionary and population or community dynamics is currently the focus of much empirical and theoretical consideration. Here, we develop a simulation model to study the coevolutionary and population dynamics of a hypothetical host-parasitoid interaction. In the model, host resistance and parasitoid virulence are allowed to coevolve. We investigate how trade-offs associated with these traits modify the systems coevolutionary and population dynamics. The most important influence on these dynamics comes from the incorporation of density-dependent costs of resistance ability. We find three main outcomes. First, if the costs of resistance are high, then one or both of the players go extinct. Second, when the costs of resistance are intermediate to low, cycling population and coevolutionary dynamics are ...

Aphidius ervi (Hymenoptera: Braconidae) is an entomophagous parasitoid known to be an effective parasitoid of several aphid species of economic importance. A reduction of its production cost during mass rearing for inundative release is needed to improve its use in biological control of pests. In these contexts, a careful analysis of its entire development phases within its host is needed. This paper shows that this parasitoid has some characteristics in its embryological development rather complex and different from most other reported insects, which can be phylogenetically very close. First, its yolkless egg allows a high fecundity of the female but force them to hatch from the egg shell rapidly to the host hemocoel. An early cellularisation allowing a rapid differentiation of a serosa membrane seems to confirm this hypothesis. The serosa wraps the developing embryo until the first instar larva stage and invades the host tissues by microvilli projections and form a placenta like structure able to
Members of this wasp species primarily attack tobacco budworms and related caterpillars. These detrimental moth caterpillars attack not only tobacco, as suggested by the common name, but also soybeans and cotton, along with many other plant species. These two crops are particularly important to the Louisiana agricultural economy, making their natural enemies important in integrated pest management of pest species. Tobacco budworms and related species of noctuid moths are among the most important of these crop pests based on a number of classical life history studies and results of current research. Because of the narrow host specificity of tobacco budworm parasitoids, several species of these wasps are important to the natural control of tobacco budworm populations. Releases of tobacco budworm parasitoids in tobacco fields have been shown to be highly effective, and wasp rearing and release programs have great potential for improving pest management of these pests in many parts of the world. ...
Overall, an individuals rival choice decisions were influenced by the advertised quality of the individual, their rivals and the interaction between the two, consistent with a process of mutual assessment. Individuals were more likely to challenge one of the guards when the guards had few facial spots than when the guards had many facial spots. Further, focal wasps with facial patterns signalling high quality were more likely to challenge one of the guards than focal wasps with facial patterns signalling lower quality.. The particular guard that individuals challenged was also influenced by the signal intensity of the focal wasp and her rivals, but the relationship is more complex. Individuals did not use a simple decision rule like always challenge the lower-quality rival. Instead, individuals chose the lower-quality rival when rivals were close to their own quality, but they were less choosy when both rivals were either higher or lower quality. For example, wasps with high-quality facial ...

August 28, 2018 - When scientists scanned 35 million-year-old fly pupae, they discovered a hidden intruder-fossilized parasitic wasps. Out of 1,510 ancient fly pupae that were discovered at a site in France, 55 housed the parasitic invaders. Several species of parasitic wasp injected their eggs into the pupae as the maggots transformed into flies. The wasps hatched inside the fly pupae and ate the young flies. Scientists identified four new wasp species among the cache of fossils.

Haplodiploidy, where females develop from diploid, fertilized eggs and males from haploid, unfertilized eggs, is abundant in some insect lineages. Some species in these lineages reproduce by thelytoky that is caused by infection with endosymbionts: infected females lay haploid eggs that undergo diploidization and develop into females, while males are very rare or absent. It is generally assumed that in thelytokous wasps, endosymbionts merely diploidize the unfertilized eggs, which would then trigger female development. We found that females in the parasitoid wasp Asobara japonica infected with thelytoky-inducing Wolbachia produce 0.7-1.2 % male offspring. Seven to 39 % of these males are diploid, indicating that diploidization and female development can be uncoupled in A. japonica. Wolbachia titer in adults was correlated with their ploidy and sex: diploids carried much higher Wolbachia titers than haploids, and diploid females carried more Wolbachia than diploid males.

An international consortium of scientists, including Universitat Autònoma de Barcelona researcher Deodoro Oliveira, have sequenced the genome of three species of parasitoid wasps of the genus Nasonia. The research offers new basic information on the genetic mechanisms of evolution. It is also of great importance for the control of agricultural pests and of insect-borne diseases.

TY - JOUR. T1 - Gene flow between sexual and asexual strains of parasitic wasps. T2 - A possible case of sympatric speciation caused by a parthenogenesis-inducing bacterium. AU - Adachi-Hagimori, Tetsuya. AU - Miura, Kazuki. AU - Abe, Yoshihisa. PY - 2011/6. Y1 - 2011/6. N2 - Sympatric speciation is strictly defined as the emergence of two species from a population in which mating has been random with respect to the place of birth of the mating partners. Mathematical models have shown that sympatric speciation is possible, but very few examples have been documented in nature. In this article, we demonstrate that arrhenotokous and thelytokous strains of a parasitic wasp, Neochrysocharis formosa, speciated sympatrically through infection by a symbiotic bacterium Rickettsia for the following reasons: First, Rickettsia infection was detected in all of the thelytokous strains collected throughout Japan. Second, the arrhenotokous and thelytokous strains have been collected sympatrically. Third, ...
Parasitoids were initially recognized from the order Hymenoptera, but later research showed that a number of families in the Diptera order and one in the Coleoptera order also contain true parasitoids. In describing parasitic insects, the term parasitoid was first used in Reuter 1913. His definition referred to an organism that goes through complete metamorphosis and whose larvae are parasitic but whose adults are free living (see Defining Parasitoids). Since that time, the term has been greatly refined to accommodate the plethora of life-history strategies that are found in parasitoids. Some of the most important pioneering research on host-parasitoid interactions was performed by George Salt (Salt 1941) and Stanley Flanders (Flanders 1942 and Flanders 1950), whose early works on development and reproduction are still considered to be of profound importance today. Their studies also influenced later generations of entomologists working on parasitoids. Doutt 1959 wrote the first comprehensive ...
Each female wasp may create more than one nest, as long as she is physically able to do so. Inside the nest, each egg takes about two days to hatch. The larva then begins consuming its larder of caterpillars. It takes an average of 4-8 days to finish eating before preparing for pupation.. The wasp larvae do not spin cocoons, but do secrete some kind of varnish that they apply over the interior walls of their cells in the course of one to three days. Each larva enters the inactive pre-pupal stage about five days after it finishes feeding. About three days later, the larva pupates (in summer generations; it may overwinter as a pre-pupa later in the year). Ten to twenty-one days elapse before an adult wasp emerges (again, for the summer generation). Males take less time to metamorphose than females. The eclosed (emerged) adult wasp then lingers inside its nest cell for another 2-3 days while its exoskeleton hardens and it is able to chew its way through the mud partition(s) to freedom.. Not all ...
I have written many times about parasitoid wasps and their lifestyle. In summary, the female wasp finds her target host - usually a caterpillar or larva of a sawfly - and deposits an egg inside it. The egg remains dormant until the host larva has grown sufficiently large and then it hatches and the wasp larva eats the host larva. Sometimes the wasp waits until the host larva has pupated, but the outcome is the same: the host dies and the wasp larva pupates and emerges as an adult wasp at a later date ...
Scientists started working with a type of parasitic wasp called Microplitis croceipes, decades ago.. Biological engineer Glen Rains says the wasps can be trained -with sugar water by using the Pavlovs conditioning techniques- to detect fungal diseases on crops while the damage is still below ground. This method would help farmers avoid having to spread toxic fungicide over an entire crop after the disease spreads. The wasps may also be trained for medical uses, including detecting cancer or ulcers by smelling someones breath. They probably can also be trained like dogs to find bodies buried in rubble.. Five wasps are placed in a plastic cylinder that is 15 inches tall. This Wasp Hound has a vent in one end and a camera that connects to a laptop computer. When the wasps pick up an odor theyve been trained to detect they gather by the vent - a response that can be measured by the computer or actually seen by observers.. The scientists say their device is ready for pilot tests and could be ...
Treasure none. Like the more powerful retriever, the warmonger wasp is a construct built from the protoplasmic flesh and chaotic fecundity of the Abyss itself. Appearing as partially organic, partially metallic, warmonger wasps serve the demonic armies as air support in large battles, and the armies of demon infested lands are no exception. Their electricity based explosions work well on battlefields where demons and mortals clash, as electrical attacks have no effect on demons. Its more accurate to say that warmonger wasps are grown rather than constructed, and while the procedure of crafting these foul constructs is beyond the ken of mortal crafters, spellcasters can conjure them to do their bidding (see below). Warmonger wasps are only intelligent enough to understand simple commands, and only ones universally associated with battlefield conditions.. In a demon infested land, a large number of warmonger wasps have been left to their own devices. These wild wasps buzz through the skies, ...
Parasitoid wasps lay their eggs on a spiders back. This team proposes that by injecting the spider host with the molting hormone, ecdysone, the wasp induces the spider to make a special web for the wasps pupa.
No one stands between me and my golden tomatoes. Bring in the mercenaries: The Good, The Bad and The Ugly!. ** Click Here To Cue The Theme Song! **. The parasitic wasp (including the hornworm destroying Braconid) is a natural, female mercenary extraordinaire. Non-stinging and pollen-eating, parasitic wasps are attracted to flowering plants in your garden, where they will happily co-exist with other beneficial insects and animals. Draw braconid wasps to your garden with creative companion planting. Adult braconids are attracted to the pollen and nectar of flowers such as Queen Annes Lace and tansy, and herb blossoms; including dill, fennel, mint and parsley. So plant lots of flowering herbs, edible blossoms and posies for picking in your potager.. The braconid wasp is a clever killer. As you can see below, its not the delicate wasp herself who actually does the dirty deed to the hornworm. Oh no… She tasks her voracious off-spring with the job; depositing her eggs on the backs of her ...
A cockroach is crawling in a dark alley, looking for the nights meal. He crawls over the human waste and rubbish, produced by the high concentration of over 12 million people in the city of Mumbai. Its paradise for a pest like him. You couldnt see him, but you might see the enemy that is about to strike. A metallic, blue-green speck, glinting softly in the yellow light coming out of the dirty glass of the apartments on either side. Its a small, solitary wasp. This wasp doesnt build nests to raise its larvae in. It doesnt work together with other wasps. And it definitely answers to no queen.. The wasp isnt looking for nectar tonight. Shes far from any flowers and has egg-laying on her tiny wasp brain. She is a jewel wasp. Jewel wasps are parasites that sting a cockroach and lay their eggs on a soft part of the roachs leg so they can emerge and enter the roachs body. But the craziest part of the whole murder mystery is that the roach remains alive after being stung and even after the ...
Interpretive Summary: Technical Abstract: Polydnaviruses do not replicate in the traditional sense of virus replication, which is one reason they have not usually been included in comprehensive reviews on DNA virus replication. Whereas in all other cases infection of host cells would lead to production of progeny virions, polydnaviruses instead have evolved by anomalous lifecycle and replication strategies requiring two insect hosts. The replication of polydnavirus DNA and packaging and production of progeny virions are limited to certain specialized cells found only in females of the parasitoid wasps where they are produced and harbored. Furthermore, replication is directed by a linear provirus form of the virus, integrated within the parasitoid wasp chromosomes. Finally, genes for most, if not all, virion structural proteins are not packaged into polydnavirus particles. Our understanding of the unique attributes of the polydnavirus particle, its formation through novel replication and life ...

Unique yeast strains. The field research by the Florence researchers has some interesting implications. Not surprisingly to Paul, the maximum number of wasps in a colony happens to coincide with the peak sugar content in vineyards (harvest time), lots of food, lots of wasps, lots of rapidly-multiplying yeast to pass on - a symbiotic relationship where everyone wins. Based on DNA sequencing, they found that genetically unique strains of yeast were passed on to the same vineyards. What makes Champagne wines different from a Sangiovese (used to make Italian Chianti) may very well be the result of the unique yeast they harbor in overwintering wasps. We can further appreciate the unique ways that nature adapts and evolves, benefiting mankind as a whole. Without these wasps, Edward FitzGeralds Rubaiyat of Omar Khayyam quote, A Jug of Wine, a Loaf of Bread - and Thou, Beside me singing in the Wilderness ., might be meaningless..

Sex pheromones have rarely been studied in parasitoids, and it remains largely unknown how male and female parasitoids locate each other. We investigated possible attraction (and repellency) between the sexes of two braconid wasps belonging to the same genus, the gregarious parasitoid, Cotesia glomerata (L.), and the solitary parasitoid, Cotesia marginiventris (Cresson). Males of both species were strongly attracted to conspecific virgin females. Interestingly, in C. glomerata, the males were repelled by mated females, as well as by males of their own species. This repellency of mated females was only evident hours after mating, implying a change in pheromone composition. Males of C. marginiventris were also no longer attracted, but not repelled, by mated females. Females of both species showed no attraction to the odors of conspecific individuals, male or female, and C. glomerata females even appeared to be repelled by mated males. Moreover, the pheromones were found to be highly specific, as males
WASP and N-WASP are predominantly found in an autoinhibited conformation in which the C-terminus of the protein is occluded through its interaction with the N-terminus. This autoinhibition is released by the competitive binding of the small GTPase Cdc42 and the phospholipid PtdIns(4,5)P2 (Kim et al., 2000), although it is not clear whether the lipid acts as a signalling molecule or merely as an anionic marker of the plasma membrane (Insall and Weiner, 2001). Other proteins are thought to bind to WASPs and regulate their activity - WIP is a frequently observed binding partner (Ramesh et al., 1997) and TOCA1, which (like WASP) binds to Cdc42, might add selectivity and cooperation to the Cdc42-dependent activation of WASPs (Ho et al., 2004). The role of SH3-domain adaptors such as Nck and Grb2 in WASP activation remains a mystery; early papers reported that they bound to the proline-rich domains of both WASP and SCAR, but these have been relatively unsupported by recent data (Buday, 1999).. Unlike ...

The dietary breadth of both the parasitoid and its host may affect the extent to which a searching parasitoid relies on HIPV. Specialist species are expected to rely on specific volatile cues to which they respond innately, whereas generalists are expected to show a higher degree of phenotypic plasticity that depends on foraging experience in the parasitoid. We compared the response to HIPV emitted by different plant species damaged by host and ...
One more group of aphid killers made their presence known this week. These are the parasitic wasps. While observing the aphid colony, two distinctly different types of aphids were seen. Some were plump, juicy, mobile aphids of green or pink. Others were strange, motionless, papery aphids light brown or tan in color. These papery aphids are called aphid mummies because of their brown parchment-like skin. Tiny parasitic wasps attacked aphid mummies. A female wasp inserted an egg through the skin of each aphid. Eggs hatched into wasp larvae that ate the internal organs of the aphid killing it in its tracks. This process caused the aphid to change from its normal color of green or pink to the telltale brown of the aphid mummy. After devouring the aphid from within the small wasp pupates in the papery shell. From the pupa emerges the wasp that chews a hole in the abdomen of the aphid, pops out, and searches for another aphid victim to sting and insert her egg, thereby completing the circle of life. ...
In nature, parasitoid wasps encounter and sometimes show oviposition behavior to nonhost species. However, little is known about the effect of such negative incidences on their subsequent host-searching behavior. We tested this effect in a tritrophic system of maize plants (Zea mays), common armyworms (hosts), tobacco cutworms (nonhosts), and parasitoid wasps, Cotesia kariyai. We used oviposition inexperienced C. kariyai and negative-experienced individuals that had expressed oviposition behavior toward nonhosts on nonhost-infested maize leaves. We first observed the olfactory behavior of C. kariyai to volatiles from host-infested plants or nonhost-infested plants in a wind tunnel. Negative-experienced wasps showed significantly lower rates of taking-off behavior (Step-1), significantly longer duration until landing (Step-2), and lower rates of landing behavior (Step-3) toward nonhost-infested plants than inexperienced wasps. However, the negative-experience did not affect these three steps ...
Endoparasitoid wasps are important natural enemies of the widely distributed aphid pests and are mainly used as biological control agents. However, despite the increased interest on aphid interaction networks, only sparse information is available on the factors used by parasitoids to modulate the aphid physiology. Our aim was here to identify the major protein components of the venom injected at oviposition by Aphidius ervi to ensure successful development in its aphid host, Acyrthosiphon pisum. A combined large-scale transcriptomic and proteomic approach allowed us to identify 16 putative venom proteins among which three γ-glutamyl transpeptidases (γ-GTs) were by far the most abundant. Two of the γ-GTs most likely correspond to alleles of the same gene, with one of these alleles previously described as involved in host castration. The third γ-GT was only distantly related to the others and may not be functional owing to the presence of mutations in the active site. Among the other abundant proteins
Sex determination has evolved in a variety of ways and can depend on environmental and genetic signals. A widespread form of genetic sex determination is haplodiploidy, where unfertilized, haploid eggs develop into males and fertilized diploid eggs into females. One of the molecular mechanisms underlying haplodiploidy in Hymenoptera, the large insect order comprising ants, bees, and wasps, is complementary sex determination (CSD). In species with CSD, heterozygosity at one or several loci induces female development. Here, we identify the genomic regions putatively underlying multilocus CSD in the parasitoid wasp Lysiphlebus fabarum using restriction-site associated DNA sequencing. By analyzing segregation patterns at polymorphic sites among 331 diploid males and females, we identify up to four CSD candidate regions, all on different chromosomes. None of the candidate regions feature evidence for homology with the csd gene from the honey bee, the only species in which CSD has been characterized, ...
Acrotaphus wasps are fascinating because they are very sizeable parasitoids. The largest species can grow multiple centimeters in length and are also very colorful. Previously, only 11 species of the genus were known, so this new research gives significant new information on the diversity of insects in rain forests, tells postdoctoral researcher and lead author of the new study Diego Pádua, who has worked both for the INPA and the Biodiversity Unit of the University of Turku.. The parasitoid Acrotaphus wasps parasitize on spiders. A female Acrotaphus attacks a spider in its web and temporarily paralyzes it with a venomous sting. After this, the wasp lays a single egg on the spider, and a larva hatches from the egg. The larva gradually consumes the spider and eventually pupates.. The Acrotaphus wasps studied are very interesting as they are able to manipulate the behavior of the host spider in a complex way. During the time period preceding the host spiders death, it does not spin a normal web ...
The study, published Wednesday in the journal ZooKeys, released details of the new species, all part of a category of parasitic wasps known as Heterospilini.. Parasitic wasps inject their eggs into other insects. When the baby wasps hatch into larvae, they feed off the hosts insides, predictably killing it. The larvae then pupate, which is a gross-sounding word for when a wasp bursts out of a dead hosts skin.. The Heteospilini have taken this already disturbing birth method to a whole new level, injecting their hosts with viruses that weaken its immune system. The virus actually comes from a template in the wasps DNA.. The studys head researcher, Paul Marsh of the University of Illinois at Champaign-Urbana, described the process as extraordinary and morbid in a press release. He also said he believes there are many more undiscovered wasps out there.. We estimate that perhaps another 50-100 species could be added to the total to contribute to the astonishing biodiversity of Costa Rica, he ...
Posted: 11/6/2018 - 1 year ago. The Issue:. In the spotted-wing drosophilas native range in East Asia, a wide number of natural enemies keep SWD numbers in check. These natural enemies include parasitoid wasps that lay eggs in SWD larvae or pupae, and then the developing wasp larvae slowly consume the flies from the inside, ultimately killing them. In North America, native parasitoid wasps rarely parasitize spotted-wing drosophila, and those that do have difficulty developing, likely due to the flys robust immune response. Introducing a more effective parasitoid wasp from the native range of SWD may help to limit SWD population growth in non-crop areas where the flies can take refuge from on-farm management tactics. If parasitoid wasps are able to reproduce fast enough and kill SWD hosts effectively, the resulting population reduction would lower cost and effort for farmers to control SWD. Obtaining information about a parasitoid wasps reproductive potential is essential to determine if it is ...
The host acceptance behaviour in Aphidius ervi is investigated, assessing the role of both external and internal host-associated cues, offered to the experimental parasitoids with parafilm-made aphid dummies. The reaction to internal cues present in the host haemolymph is clearly evident, and its intensity is enhanced by external cues. Parasitoid females lay few eggs in aphid dummies filled with host haemolymph. A significant increase in the number of both oviposition reactions (host stinging) and egg laying is observed only when these dummies are coated with cornicle secretion. However, this enhancement is not observed when the aphid dummies contain distilled water. Thus, the host acceptance behaviour of A. ervi females appears to be controlled by the integration of both external and internal chemical cues. The physiological basis of this behavioural response is investigated with a detailed study on the anatomy and ultrastructure of A. ervi ovipositor. The detection of chemical cues present in ...
Polydnaviruses are double-stranded DNA viruses associated with some subfamilies of ichneumonoid parasitoid wasps. Polydnavirus virions are delivered during wasp parasitization of a host, and virus gene expression in the host induces alterations of host physiology. Infection of susceptible host caterpillars by the polydnavirus Campoletis sonorensis ichnovirus (CsIV) leads to expression of virus genes, resulting in immune and developmental disruptions. CsIV carries four homologues of insect gap junction genes (innexins) termed vinnexins, which are expressed in multiple tissues of infected caterpillars. Previously, we demonstrated that two of these, VinnexinD and VinnexinG, form functional gap junctions in paired Xenopus oocytes. Here we show that VinnexinQ1 and VinnexinQ2, likewise, form junctions in this heterologous system. Moreover, we demonstrate that the vinnexins interact differentially with the Innexin2 orthologue of an ichnovirus host, Spodoptera frugiperda. Cell pairs coexpressing a ...
Gene duplications have been recognized as an important source of evolutionary innovation and adaptation in a variety of organisms [1-5]. Here we study gene duplications in the genomes of a virus group, the polydnaviruses (PDVs), which are unique in their obligatory association with parasitoid wasps. We analyze a gene family which has been subjected to particularly strong expansion. The genes encode Protein Tyrosine Phosphatases (PTPs), well known in vertebrates for their role in regulation of signal transduction pathways.. PDVs are stably integrated as proviruses in the genome of their associated parasitoid wasps [6-8] and transmitted exclusively by chromosomal inheritance. Particle replication is restricted to wasp ovaries, and virus particles are injected into the lepidopteran host of the wasp during oviposition at the same time as wasp eggs. PDV particles enter host cells, but unlike pathogenic viruses they do not replicate in the infected cells. Instead they express a battery of genes that ...

Quantification of a glyptapanteles indiensis polydnavirus gene expression in its parasitized host, lymantria dispar by real-time quantitative rt-pcr. Insect Biochemistry and Molecular Biology. Interpretive Summary: Parasitic wasps have great potential for the control of moth species that are pests of agricultural crops and forests. The survival of many of these parasites is enhanced by a virus, called a polydnavirus, that is injected along with the wasp egg into the host caterpillar. In the current paper, we have used modern molecular techniques to analyze expression of a polydnavirus gene that may be involved in protecting the parasitic wasp egg and assisting the wasp survival. We found the protein associated with this virus gene was made soon after infection at a high level in the caterpillar pest hemolymph (insect blood). This knowledge may help us to understand how the virus assists in the wasps survival, information which may lead to ...
Honey bees (genus Apis) are well known for the impressive suite of nest defenses they have evolved to protect their abundant stockpiles of food and the large colonies they sustain. In Asia, honey bees have evolved under tremendous predatory pressure from social wasps in the genus Vespa, the most formidable of which are the giant hornets that attack colonies in groups, kill adult defenders, and prey on brood. We document for the first time an extraordinary collective defense used by Apis cerana against the giant hornet Vespa soror. In response to attack by V. soror, A. cerana workers foraged for and applied spots of animal feces around their nest entrances. Fecal spotting increased after colonies were exposed either to naturally occurring attacks or to chemicals that scout hornets use to target colonies for mass attack. Spotting continued for days after attacks ceased and occurred in response to V. soror, which frequently landed at and chewed on entrances to breach nests, but not Vespa velutina, a

Many animals avoid attack from predators through toxicity or the emission of repellent chemicals. Defensive mimicry has evolved in many species to deceive shared predators, for instance through colouration and other morphological adaptations, but mimicry hardly ever seems to involve multi-trait similarities. Here we report on a wingless parasitoid wasp that exhibits a full spectrum of traits mimicing ants and affording protection against ground-dwelling predators (wolf spiders). In body size, morphology and movement Gelis agilis (Ichneumonidae) is highly similar to the black garden ant (Lasius niger) that shares the same habitat. When threatened, G. agilis also emits a volatile chemical that is similar to an ant-produced chemical that repels spiders. In bioassays with L. niger, G. agilis, G. areator, Cotesia glomerata and Drosophila melanogaster, ants and G. agilis were virtually immune to spider attack, in contrast the other species were not. Volatile characterisation with gas ...
Mutualisms are interactions between two species in which the fitnesses of both symbionts benefit from the relationship. Although examples of mutualism are ubiquitous in nature, the ecology, evolution, and stability of mutualism has rarely been studied in the broader, multi-species community context in which they occur. The pollination mutualism between figs and fig wasps provides an excellent model system for investigating interactions between obligate mutualists and antagonists. The fig pollination mutualism is exploited by a diverse community of non- pollinating fig wasps that develop within fig fruit at the expense of fig seeds and pollinators. Much less well studied, however, are consequences of the interaction between female pollinating wasps and their host-specialist nematode parasites. Here we focus on a tri-trophic system comprised of a fig (Ficus petiolaris), pollinating wasp (Pegoscapus sp.), and nematode (Parasitodiplogaster sp.), investigating geographical variation in the incidence ...
strangler fig Some fig species are dependent on specific wasps species for pollination. The wasps use fig fruit as a safe place to lay their eggs. If a wasp species linked to a particular fig were ever to become extinct, so too would the fig. The symbiotic relationship between the fig and wasp works like this: A female wasp, carrying pollen from male flowers inside the fig where she was born, enters the fig through an entryway at the bottom of the fruit. She lays her eggs in figs ovaries, spreading pollen from the male flowers as you goes. This allows the fig to reproduce. After she is finished she dies. Young wasp larvae emerge from the eggs and feed on the fruits flesh and mate. Male wasps die inside the fruit and females, covered with pollen, emerge to begin the cycle again. Many animals and birds eat the fruit produced by strangler figs. Unlike fruit trees such as mangos that produce all their fruit at once during one season, each species of strangler figs produce fruit year round. ...
Alien parasitic wasps, including accidental introductions and purposefully released biological control agents, have been implicated in the decline of native Hawaiian Lepidoptera. Understanding the potential impacts of alien wasps requires knowledge of ecological parameters that influence parasitism rates for species in their new environment. Sophora seed-feeding Cydia spp. (Lepidoptera: Tortricidae) were surveyed for larval parasitoids to determine how native and alien wasps are partitioned over an elevation gradient (2200-2800 m) on Hawaii Island, Hawaii. Parasitism rate of native Euderus metallicus (Eulophidae) increased with increased elevation, while parasitism rate by immigrant Calliephialtes grapholithae (Ichneumonidae) decreased. Parasitism by Pristomerus hawaiiensis (Ichneumonidae), origins uncertain, also decreased with increased elevation. Two other species, Diadegma blackburni (Ichneumonidae), origins uncertain, and Brasema cushmani (Eupelmidae), a purposefully introduced biological control
An inventory of wild-caught caterpillars, its food plants and parasitoids, has been going on for more than 34 years in Area de Conservación Guanacaste (ACG), a protected area of approximately 1200 km2 in northwestern Costa Rica. As a result, more than 10,000 species of moths and butterflies are estimated to live in ACG. Their caterpillars are in turn attacked by many parasitoid wasps, also numbering thousands of species. However, most of those wasps have never been described and remain unknown.

Differential interference contrast (DIC) micrograph of a beetle larva living on the mouthparts of a spider-hunting wasp. The beetle is a 1st instar larva of either a rhipiphorid (an unusual family of beetles), or possibly a twisted-wing fly (Strepsiptera). Both Rhipiphorids and Strepsiptera are partially parasitoids of bees or wasps, though they are also known to attack other hosts. The tiny 1st instar larvae are known as triungulins, and board adult bees or wasps (Hymenoptera), in order to be brought back to their nests. Once there, the triungulin attacks either the larvae of the bee or wasp as a parasitoid, or the host of the wasp. Length of beetle larva is 0.1 mm.
BACKGROUND: While modulation of T cell function is believed to be important in the successful acquisition of clinical tolerance during venom immunotherapy, little is known of the role of wasp venom specific T cell antigens. OBJECTIVE: We sought comprehensively to characterize the T cell proteome for wasp venom to facilitate the future development of T cell-based immunotherapeutic approaches. METHODS: Using peripheral blood mononuclear cells from wasp venom-allergic individuals and IL-4 ELISPOT analysis, we characterized T cell responses to whole venom and gel filtration/ion exchange-fractionated venom. Reactive fractions were purified and identified using highly sensitive electrospray ion-trap mass spectrometry. RESULTS: Wasp venom-allergic individuals have detectable whole wasp venom-specific T cells directly ex vivo, which show rapid IL-4 effector function. T cell responses to gel filtration/ion exchange fractionated venom were dominated by responses to phospholipase A(1), hyaluronidase and antigen 5.
The Samsung Galaxy Gear is a somewhat unusual device. The smartwatch was originally designed for the Samsung Galaxy Note 3 and Galaxy S 4 flagships, and quickly became one of the most popular devices in its category. Despite this, its still up for debate whether the Galaxy Gear will ever become a commercially successful device. This doesnt change the fact that development on XDA is quite fruitful, as weve already covered a custom ROM made by XDA Senior Member fOmey.. Those of you who use Sony devices may be familiar with XDA Recognized Developer lilstevie. If your memorys a little rusty, he managed to release LittleKernel and a custom bootloader for several Sony devices some time ago. Recently, lilstevie decided to put his efforts into kernel development for the Galaxy Gear, and thats how Triangulum kernel was born.. Triangulum is the first custom kernel for the Galaxy Gear, and it adds a few nice things like auto-rooting, init.d support, and most importantly, it unlocks the devices second ...

In contrast to the previous examples where manipulated hosts played an active and direct role against natural enemies of the parasitoid, the following studies describe cases where the host is manipulated prior to parasitoid pupation in order to provide shelter against potential biotic and abiotic threats. Although these bodyguards do not directly face the threats, the benefits for parasitoid survival are equally important.. With their studies on the aphid parasitoid Aphidius nigripes, Brodeur and McNeil tested the hypothesis that parasitic wasps could avoid natural enemies in time or space through the selection of suitable pupation sites by modifying the behaviour of their host (Brodeur and McNeil, 1989; Brodeur and McNeil, 1992) (Table 1). Aphidius nigripes, an endoparasitoid of the potato aphid Macrosiphum euphorbiae, completes its pupal development within its eviscerated host (termed mummy). Inside the mummy, the parasitic wasp spins a cocoon and pupates (Fig. 1D). In this state, it remains ...
The monarch butterfly, along with the silkworm and many other types of butterflies, have been found to be genetically modified by parasites, more specifically, genes from parasitic wasps. Researchers discovered that These genes were acquired through a virus that weaves in and out of DNA...Parasitic insects known as braconid wasps lay their eggs inside the caterpillars of butterflies and moths. The wasp larvae that hatch from the eggs typically kill the host caterpillars (Live Science). The wasps also inject what is called a bracovirus, which can then incorporate themselves into the genomes of caterpillars. These viruses benefit the parasite, allowing it to live freely inside its host, the caterpillar, and from there, can then weave themselves into the hosts genomes, allowing the virus to inhibit the immune defense of the host, protecting the larvae of the wasp (Live Science ...
1) Struggle: A parasitoid wasp locates a cockroach and grabs it by the pronotum. (2) Head sting: The wasp injects a venom cocktail into the preys cerebral ganglia. The cockroach shown here was anaesthetized and tethered to allow filming from below. (3) Host feeding: The wasp cuts the cockroachs antennae and feeds off hemolymph from the cut end. Notice that the cockroach does not escape the wasp, although it is not paralyzed. (4) Host transportation: The wasp grabs the cockroach by the antenna stump and walks backward toward its nest, while the cockroach follows in a docile manner. Notice the expression of an alternating-tripod gait when the cockroach is following the wasp. (5) Host concealment: The cockroach is inserted into the wasps nest without resisting or trying to escape. (6) Oviposition: The wasp lays one egg on the cockroach leg and exits the nest. The cockroach stays at the same spot, although it is not paralyzed. (7) Entombment: The wasp collects nearby pieces of paper and seals the ...
TY - JOUR. T1 - Culture-Free Survey Reveals Diverse and Distinctive Fungal Communities Associated with Developing Figs (Ficus spp.) in Panama. AU - Martinson, Ellen O.. AU - Herre, Edward Allen. AU - Machado, Carlos A.. AU - Arnold, A. Elizabeth. PY - 2012/11/1. Y1 - 2012/11/1. N2 - The ancient association of figs (Ficus spp.) and their pollinating wasps (fig wasps; Chalcidoidea, Hymenoptera) is one of the most interdependent plant-insect mutualisms known. In addition to pollinating wasps, a diverse community of organisms develops within the microcosm of the fig inflorescence and fruit. To better understand the multipartite context of the fig-fig wasp association, we used a culture-free approach to examine fungal communities associated with syconia of six species of Ficus and their pollinating wasps in lowland Panama. Diverse fungi were recovered from surface-sterilized flowers of all Ficus species, including gall- and seed flowers at four developmental stages. Fungal communities in syconia and ...
Parasitoids commonly forage in agricultural settings where the predominant sugar source is homopteran honeydew. The aphidiine braconid, Binodoxys communis, is an Asian parasitoid currently being released against the soybean aphid, Aphis glycines, in North American soybean fields. We conducted a number of laboratory experiments evaluating the quality of A. glycines honeydew as a sugar source for this parasitoid. Wasps readily fed on droplets of A. glycines honeydew, honey and 50% sucrose solution, but the length of feeding bouts on honey was significantly longer than on the other foods. Parasitoids lived significantly longer when fed honey or sucrose than honeydew, while starved wasps had the shortest lifespan. At 21±1 °C and 25±5% R.H., male B. communis that were fed honey lived for a maximum of 14 days, while females lived up to 20 days. Honeydew-fed wasps of both sexes lived approximately 3 days on average, which was 2-3 times longer than when they were only allowed access to water. ...
A social parasite uses workers of another social insect species to rear its own progeny. They are often so closely related to their hosts that it has been suggested that they could have evolved sympatrically from them. To address the question of whether social parasites evolved from their hosts we present a partial sequence of the mitochondrial 16S rRNA gene for nine species of Polistes, comprising all known species of social parasites, their hosts and two outgroups. Parsimony and maximum-likelihood analyses of the data support monophyly for these social parasites. The trees supporting monophyly are significantly shorter than the trees supporting sympatric speciation of parasites from their hosts. These data support the hypothesis that speciation occurred allopatrically and independently of the evolution of social parasitism. Where the social parasite parasitizes more than one species, the two species used are most closely related to each other. Although social parasites are monophyletic and did ...

Previous research showed that the presence of competitors was linked with increased soldier production in C. floridanum. Smith and colleagues tested whether other external factors were also related. (Shifts in caste development in other insect groups are commonly exhibited as responses to environmental conditions.) They found, however, that heat shock and bacterial infection had no influence on soldier production. Only multiparasitism, in the form the presence of competitor parasitoid Microplitis demolitor, led to increased soldier production in their experiment.. What about M. demolitor causes C. floridanum to shift toward more soldier production? The researchers tested that, too, and found that the M. demolitor egg chorion is the trigger.. As C. floridanum embryos proliferate, the differentiator between reproductive and soldier larvae is the presence or absence of a primary germ cell during embryo division. Embryos without the primary germ cells become soldier larvae. Smith and colleagues ...
The immunological relationship between different Vespula species has been demonstrated by in vitro specific IgE measurements (RAST) and RAST-inhibition studies (13). Significant immunological differences among the species were found and these differences correlated with the morphological, behavioral and ecological characteristics of the species. Cross-reactivity between venoms from yellow jacket (Vespula spp), hornets (Dolichovespula spp, i2 or i5 and Vespa spp, i75) and wasp (Polistes spp, i4) has also been investigated by specific IgE measurements and RAST inhibition studies (2-3). These studies showed that there are varying extents of antigenic cross-reactivity between venoms, depending on the patient sera. The results reflect in part the variable immune response of patients to venoms because venoms are mixtures of allergens. Cross-reactivity between different major allergens from yellow jacket (YJ) and from honeybee and different wasp and hornet species has been identified (4-6). There is a ...

Not live aphids. These are the remains of aphids after they have been parasitised by braconid parasitoid wasps and are referred to as aphid mummies. These wasps are natural predators and do a pretty good job at keeping aphid levels low if you dont spray insecticide. If you just use a jet of water to remove live adult aphids (which are black or green), the mummies stay put. They are also produced commercially and you can transfer the mummies to other plants with aphids, assuming the adult wasps havent emerged ...

Predators and parasitoids are important natural enemies of herbivorous insects. By reducing the abundance of herbivores, they can help protect plants from damage. Parasitoids in particular can use herbivore-induced plant volatiles (HIPVs) as host-searching cues [1, 2]. Such volatile-mediated tritrophic interactions have a considerable potential to shape ecosystem dynamics [3], but it remains unclear to what extend the plant signals are emitted by the plant to specifically attract natural enemies of herbivores [4]. If HIPVs are indeed emitted by the plant to attract the third tropic level, specificity of the signals should be an important aspect of the interactions [5]. This is particularly relevant under natural conditions, where plants are often attacked by non-hosts or by multiple herbivores simultaneously. While specialist parasitoids can distinguish between plants attacked by hosts and plants attacked by non-hosts using HIPV cues [6], the impact of non-hosts feeding on the same plant as the ...

The higher the energy of a particle is above equilibrium, the faster it relaxes because of the growing phase space of available electronic states it can interact with. In the relaxation process, phase coherence is lost, thus limiting high-energy quantum control and manipulation. In one-dimensional systems, high relaxation rates are expected to destabilize electronic quasiparticles. Here, we show that the decoherence induced by relaxation of hot electrons in one-dimensional semiconducting nanowires evolves non-monotonically with energy such that above a certain threshold hot electrons regain stability with increasing energy. We directly observe this phenomenon by visualizing, for the first time, the interference patterns of the quasi-one-dimensional electrons using scanning tunneling microscopy. We visualize the phase coherence length of the one-dimensional electrons, as well as their phase coherence time, captured by crystallographic Fabry-Perot resonators. A remarkable agreement with a ...

  • The first wasp that Hank and Stone currently release, an as yet unnamed species of the genus Avetianille, preys only on eggs and may catch 80 percent of them. (
  • Horntails are often called "wood wasps," probably because their eggs are laid in wood, and their young spend both their larval and pupal stages there. (
  • Most wasps live solitary lives, and when the time comes to lay eggs, they build a variety of types of nursery chambers, provision them with food for their potential young. (
  • The most familiar wasps belong to Aculeata , a division of Apocrita, whose ovipositors (an organ typically used for laying eggs) are adapted into a venomous stinger. (
  • Originating from China, the wasps leave their eggs on the leaves of the trees, preventing them from having flowers, and hence growing and reproducing. (
  • There is a wasp that lays its eggs tobacco hornworm. (
  • The interior of the syconium provides a secure incubator for fig wasp eggs, and habitat and nutrition for the wasps' larvae and young adults, while the flowers inside the syconium receive from the fig wasps the benefit of being pollinated by the adult that enters the fig to lay her eggs inside it. (
  • 2004). Females have an ovipositor-an organ used for laying eggs-that in some species of wasps, ants, and bees has been modified for a defense function rather than an egg-laying function. (
  • A modern parasitic cotesia wasp lays its eggs inside a caterpillar after giving it a paralyzing taste of its stinger. (
  • Some modern parasitic wasps continue this very practice, either peppering the outsides or filling the bodies of their hosts with dozens of eggs. (
  • They could also clearly see sensory structures at the tip that could help guide the ovipositor to the best locations for the wasp to lay her eggs. (
  • Ammophila is the type genus of the subfamily Ammophilinae of the hunting wasp family Sphecidae . (
  • The final chapter is a comparative discussion of social behavior in the Sphecidae, the only family of wasps besides the Vespidae in which well-developed social behavior is known. (

  • The venom in a wasp sting contains a pheromone that acts like an alarm to other wasps and which is also emitted when a wasp dies. (
  • Hornet stings are also more painful to humans than typical wasp stings because of the chemicals found in hornet venom. (
  • Wasp venom is toxic. (
  • Wasps carry this venom. (
  • The venom the wasp uses to produce this amazing change in cockroach behavior has not been identified by any known catalyst, due to the evolution of the toxin to the specific purpose of deactivating roach brains. (

  • The wasp venom contains active amines (serotonin and histamine), wasp kinins and histamine-releasing peptides (mastoparans) [ 5 ]. (
  • In our case, blackish necroses were formed on the site of the sting after 1 month, possibly because of severe cytotoxicity of the wasp venom. (
  • Cockroach wasp venom blocks receptors of the neurotransmitter octopamine, which is involved in the initiation of spontaneous movement. (
  • The parasitic jewel wasp uses a venom injected directly into a cockroach's brain to inhibit its victim's free will, scientists have discovered. (
  • The team determined that the wasp injects its venom into a specific area of the cockroach's brain, the protocerebrum. (
  • When bees or wasps sting a person, they inject venom through their stinger into the skin of the victim. (
  • When bees or wasps sting an individual, they inject venom under the skin of their victim. (
  • The quick jab takes only a few seconds, and venom compounds work fast, paralyzing the cockroach temporarily so the wasp can aim her next sting with more accuracy. (
  • Scientists have shown that this behavior is specific to the venom, as piercing the head, generally stressing the cockroach, or contact with the wasp without stinging activity did not elicit the same hygienic urge. (
  • However, even without a lodged stinger, wasp venom can cause significant pain and irritation. (
  • Anaphylaxis occurs when your body goes into shock in response to wasp venom. (

  • Solitary wasps do not attend their young. (
  • If you find bees or wasps in the water, it's best to remove them to avoid being stung. (
  • A 75-year-old Japanese man was stung by wasps on the head and the extremities while cutting down a tree in the countryside. (
  • These are effective in that they don't irritate the wasps (there's very little heat generated unlike an open fire) and there's less of a chance that you will get stung. (
  • About 3% of people stung by bees and wasps have an allergic reaction to the sting, and up to 0.8% of bee sting victims experience the severe and life-threatening allergic reaction known as anaphylaxis. (

  • Watch silent video clips of the wasps dropping ants. (
  • Grangier and colleague Philip Lester had suspected that the alien wasps were competing with native ants for scarce protein sources in New Zealand beech forests. (
  • This led the pair to establish an experiment in which ants and wasps were presented with samples of high-protein food: little chunks of tuna fish. (
  • In the vast majority of instances, the wasps and ants avoided or ignored each other. (
  • However, the researchers documented 341 cases when the ants were aggressive toward the wasps, charging at the larger bugs, biting them, or spraying them with formic acid, a natural defense mechanism. (
  • It was a surprise to see that ants, being 200 times smaller than wasps, can be serious competitors with them,' Grangier said. (
  • Most of the time, the wasps' ant-dropping behavior was unprovoked, with ants being simply grabbed and flown away. (
  • By not crushing ants and dropping them away as fast as possible, wasps just protect themselves, avoiding further contact with this harmful substance,' Grangier said. (
  • Velvet ants (family Mutillidae) are parasites of ground-nesting wasps and bees. (
  • These wasps are tiny black creatures, smaller than ants. (
  • The wasps, bees , and ants together make up the suborder Apocrita , characterized by a constriction between the first and second abdominal segments called a wasp-waist (petiole), also involving the fusion of the first abdominal segment to the thorax. (

  • While their contribution to pollination may not be as substantial as bees', wasps still play a valuable part. (
  • Bees and wasps help with garden pollination, after all, and we need them around to some degree. (
  • Fig trees exhibit remarkably varied reproductive patterns, which provide the backdrop for the complex, symbiotic interplay between fig wasps and figs. The dependence of the fig flowers on the pollination services of the fig wasp, and the dependence of the fig wasp on the habitat and nutrition services of the fig fruit-bodies exemplifies the particular kind of symbiotic relationship known as obligate mutualism . (
  • Wasps or yellow jackets eating the leaves? (
  • That's possible I s'pose, but more than likely the wasp or yellow jackets were going after the aphids or whatever, which were (or are) the ones that are really eating the leaves. (
  • As is frequent in large genera, considerable variation occurs in their habits and appearance, but predominantly they are medium-sized wasps of strikingly slender build, with antennae about as long as the head plus thorax. (
  • Wasps communicate visually and through their antennae. (
  • Wasps employ different means of communication--their antennae, without which a wasp would be deaf, unable to smell or hear, and pheromones which a queen uses to attract a mate and control her workers. (
  • The antennae are covered with short, sensitive hairs that help the wasp identify objects more effectively than we can with our fingers. (
  • When wasps meet, they communicate through their antennae. (
  • Normal cockroaches are amazing evaders of potential predators, running 70-80 cm/s while changing direction based on shifting air currents over its anal cerci, but the placid state the cockroach enters after the second sting leaves it so open to suggestion that the wasp can actually hold onto its antennae and ride it , directing its movement into a burrow. (

  • There are basically two types of wasps. (
  • What are the types of wasps? (
  • A wasp larva does not start out 'smelling' the same, so they conclude that it must acquire the colony odour. (
  • Ampulex compressa, or jewel wasp, is a solitary parasitoid which uses cockroach es as the host for its larva. (
  • The wasp larva hatches and feeds on the spiders. (
  • Many other wasp species also use complex venoms to parasitize spiders, caterpillars and even wasp larvae-sometimes turning them into zombie larva defenders. (
  • This tiny wasp larva forces its host, an orb spider, to do its bidding before killing it. (
  • If the wasp had reordered the DNA, the behavior wouldnt show up untill the next generation of the spider, except since the larva kill the spider, thats never gonna happen. (
  • D. media is a medium to large species of wasp around 16-22 millimetres (0.63-0.87 in) in length with yellow and black stripes on its abdomen. (
  • You can spot a wasp by its bright yellow and black rings, defined waist and tapered abdomen. (
  • Despite its impressive abdomen, a pelecinid wasp does not have a stinger. (
  • The roach remains docile while the egg hatches, and the larvae behaves as the larvae of other parasitoid wasps, entering through the abdomen of the cockroach. (
  • The larvae then weaves a cocoon within the cockroach's abdomen, eventually emerging from the cockroach as a fully developed wasp. (
  • All wasps generally have an abdomen somewhat narrowed at the base (the so-called wasp-waist), a body with simple hairs (contrasting with the branched hairs of bees) and an ovipositor that may be modified into a sting. (
  • The long, arched abdomen is similar to that of an Ichneumon wasp, but CWs have a noticeable neck, and the tibias on its back legs are enlarged. (
  • In suborder Symphyta , (sawflies, horntails, and wood wasps), there is a broad connection between the abdomen and the thorax. (
  • Wasps also have a constricted region (the petiole) joining the first and second segments of the abdomen (the first segment is part of the mesosoma, the second is part of the metasoma). (
  • Some were spread up to 10 miles around the original release site, indicating that the wasps have established colonies in that area. (
  • It is a solitary wasp, but colonies of wasps nest in the same location. (

  • Cuckoo Wasps are found worldwide except in Antarctica. (
  • The larvae of some species of cuckoo wasps feed on the larvae of the nest-builder, usually another wasp, a bee, a silk moth or a walking stick. (
  • For more than 200 years, researchers have struggled to sort cuckoo wasps into the right "species boxes" and to determine which characteristics are variations within a species and which are species-specific differences. (
  • But over the last decade DNA barcoding has brought about a major breakthrough by making it possible to distinguish different species of cuckoo wasps from each other by looking at the differences in their genetic material. (
  • In this case, we had two cuckoo wasps with microscopic differences in appearance and very small differences in DNA. (
  • By conducting what the researchers described as "an ever-so-small language study", the scientists discovered that the two almost identical cuckoo wasps did indeed belong to different species. (
  • A naming competition was announced among researchers in Europe who work with cuckoo wasps, and then the proposals that came in were voted on. (
  • 2014). Cuckoo wasps, excluding Amiseginae and Loboscelidiinae, which are not present in Europe, are well known for their bright metallic colours and cleptoparasitic or parasitoid lifestyle. (
  • Wasps and many bees can sting more than once because they can pull out their stinger without injuring themselves. (
  • The stinger is not barbed, so the wasp can sting repeatedly. (
  • The wasp, which is often just a fraction of the size of her victim, begins her attack from above, swooping down and grabbing the roach with her mouth as she aims her "stinger"-a modified egg-laying body part called an ovipositor-at the middle of the body, the thorax, in between the first pair of legs. (
  • scientists have artificially clipped them from cockroaches to see how the wasp reacts, and when they are removed, the wasp tries to find them, taking a long time with her stinger embedded in search of the missing brain regions. (
  • Other wasps evolved away from the practice, but the venomous stinger remains -- no longer an instrument of reproduction, but a potent biological weapon. (
  • When on the hunt for nectar, wasps can also become accidental pollinators by travelling from plant to plant carrying pollen. (

  • [6] The median wasp has a halplodiploid sex determination system that results in a high level of relatedness within the colony. (
  • The size of the territory a wasp will defend varies with each species and size of the colony, but in general, wasps can detect the release of pheromones within a 20 foot radius. (
  • This sometimes makes wasps a pest problem when the colony mass increases. (
  • According to Robert Vander Meer, a chemical ecologist working with Jouvenaz, it's during this time that the wasp 'passively acquires' the odour of the colony or nest. (
