Although molecular analyses have contributed to a better resolution of the animal tree of life, the phylogenetic position of tardigrades (water bears) is still controversial, as they have been united alternatively with nematodes, arthropods, onychophorans (velvet worms), or onychophorans plus arthropods. Depending on the hypothesis favoured, segmental ganglia in tardigrades and arthropods might either have evolved independently, or they might well be homologous, suggesting that they were either lost in onychophorans or are a synapomorphy of tardigrades and arthropods. To evaluate these alternatives, we analysed the organisation of the nervous system in three tardigrade species using antisera directed against tyrosinated and acetylated tubulin, the amine transmitter serotonin, and the invertebrate neuropeptides FMRFamide, allatostatin and perisulfakinin. In addition, we performed retrograde staining of nerves in the onychophoran Euperipatoides rowelli in order to compare the serial locations of motor

In Drosophila, the T-box genes optomotor-blind (omb) and H15 have been implicated in specifying the development of the dorso-ventral (DV) axis of the appendages. Results from the spider Cupiennius salei have suggested that this DV patterning system may be at least partially conserved. Here we extend the study of the DV patterning genes omb and H15 to a representative of the Myriapoda in order to add to the existing comparative data set and to gain further insight into the evolution of the DV patterning system in arthropod appendages. The omb gene of the millipede Glomeris marginata is expressed on the dorsal side of all appendages including trunk legs, maxillae, mandibles, and antennae. This is similar to what is known from Drosophila and Cupiennius and suggests that the role of omb in instructing dorsal fates is conserved in arthropods. Interestingly, the lobe-shaped portions of the mouthparts do not express omb, indicating that these are ventral components and thus may be homologous to the ...

The super worm (Zophobas morio) is a larva of a species of darkling beetle. Only the larvae are fed out to amphibians, as the adult are not preferred foods for frogs. This insect goes through complete metamorphosis.. We also have a colony of earthworms. Our colonies are not thriving at the moment, so most of the time we harvest from our own backyard. The other food item that we are currently not breeding, but do feed out, is the Neoconocephalus saturatus, a type of cone-headed katydid. We rely on a local family to help us out by collecting these katydids for us.. Last, but certainly not least, is the newest food item on the menu at EVACC; Blaberus discoidalis, a very large cockroach.. ...

The tempo and mode of cryptobiosis evolution within tardigrades are still unknown, but it is clear that comprehending this process is the key to better understand evolutionary history and ecology of this phylum, and the process of animal terrestrialization, given the ubiquitous continental distribution of tardigrades. Our study was mainly aimed at timing tardigrade radiation and key events in tardigrade evolution. Given the existence of two lineages of continental tardigrades, i.e. Eutardigrada and Echiniscidae, we decided to implement a relaxed molecular clock based approach to attempt to derive a minimal time interval for tardigrade terrestrialization. Data from new and Genbank partial 18S and 28S rDNA sequences of 41 specimens, belonging to 31 species from 26 genera, representing all known tardigrade orders and superfamilies, were acquired. Phylogenetic inference was achieved using Bayesian mixture models that have allowed the most accurate estimates of evolutionary rates. The following ...

Venomous animals have evolved with sophisticated bio-chemical strategies to arrest prey and defend themselves from natural predators. In recent years, peptide toxins from venomous animals have drawn considerable attention from researchers due to their surprising chemical, biochemical, and pharmacological diversity. Similar to other venomous animals, centipedes are one of the crucial venomous arthropods that have been used in traditional medicine for hundreds of years in China. Despite signifying pharmacological importance, very little is known about the active components of centipede venoms. More than 500 peptide sequences have been reported in centipede venomous glands by transcriptome analysis, but only a small number of peptide toxins from centipede has been functionally described. Like other venomous animals such as snakes, scorpions, and spiders, the venom of centipedes could be an excellent source of peptides for developing drugs for treatments as well as bio-insecticides for agrochemical

Phylum Onychophora Phylum Onychophora: Velvet worms, Peripatus. All modern Onychophorans are terrestrial but fossils, which date back to the Cambrian, are mainly from marine sediments. Onychophorans look a bit like slugs with legs and when first described in 1825 were thought to be mollusks. However, now placed at the base of the Arthropod family tree.

The observations from the recent period revealed that the Western Carpathians, a part of the Carpathian mountain chain, is the northernmost region in Europe with the occurrence of the obligate cave fauna. The collembolan genus Pseudosinella Schäffer, 1897 is a polyphyletic taxon derived from the genus Lepidocyrtus Bourlet, 1839 from which it differs in reduced number of eyes. It covers about 350 species with predominantly Holarctic distribution of which about 39% are confined to caves. We studied the morphology and molecular traits to identify cave species of the genus Pseudosinella occupying the Western Carpathian caves and clarify their phylogenetic relationships. Based on morphological traits we hypothesized that Pseudosinella aggtelekiensis (Stach, 1929) and P. paclti Rusek, 1961 are descendants of the different phyletic lineages, the former species lacking morphologically related edaphic species. On the other hand, several species related to P. paclti were found in caves, superficial subterranean

An experimental procedure using biotin-labelled probes and streptavidin-bound magnetic beads (FIASCO) was used to produce a microsatellite-enriched library for the collembolan Orchesella villosa. PCR primers were successfully constructed for seven loci containing, respectively, five pure, one interrupted, and one compound dinucleotide microsatellite repeats. As a preliminary test of their variability, we investigated 15 individuals from 5 locations inside a dismissed mining area in southern Tuscany. All microsatellite loci showed high levels of polymorphism. The mean number of different alleles at each locus across populations was 10.1 and observed heterozygosity per locus was 0.13-0.86. Only 2 out of the 7 loci appeared to be in Hardy-Weinberg equilibrium. The potential application of these loci to test the effects of environmental contamination on the genetic structure of exposed populations is discussed.. ...

Hemocyanins (also spelled haemocyanins and abbreviated Hc) are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O2). They are second only to hemoglobin in frequency of use as an oxygen transport molecule. Unlike the hemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph. Oxygenation causes a color change between the colorless Cu(I) deoxygenated form and the blue Cu(II) oxygenated form. Hemocyanins are found only in the Mollusca and Arthropoda: the earliest discoveries of hemocyanins were in the snail Helix pomatia (a mollusc) and in the horseshoe crab (an arthropod). They were subsequently found to be common among crustaceans and are utilized by some land arthropods such as the tarantula Eurypelma californicum, the emperor scorpion, and the centipede Scutigera coleoptrata. Also, ...

I recently moved into a small studio an an historic building (old!) and there have been quite a few centipede visitors in the night. I dont seem to be able to catch them so I end up just chasing them away. One afternoon when I came home from work I noticed both my cats were in the bathtub playing with a huge centipede. I use the word playing deliberately because I stood and watched the three of them silently for about a minute, and was amazed at how unafraid the insect was of the two mammals. It just waddled around as though it were teasing the cats. Finally I yelled, Hey! and stomped my foot. The cats froze to look at me and the centipede zipped down the drain as fast as lightning. Very curious. It was as if it knew I was dangerous, and the cats were not. ...

The House Centipide Scutigera coleoptrata Xini Ta`l-Indewwa is unfortunately a well considered pest locally. Originally endemic to the Mediterranean region, the species has spread to other parts of the world, where it usually lives in human homes. This species can live its entire life inside a building, usually the ground levels of homes. They are generally considered harmless to humans. Bites are not common, and the jaws of most house centipedes are not strong enough to penetrate human skin . the latter feed on spiders, bedbugs, termites, cockroaches, silverfish, ants, and other household arthropods. They administer venom through modified legs. These are not part of their mandibles, so strictly speaking they sting rather than bite. They are mostly nocturnal hunters. Despite their developed eyes they seem to rely mostly on their antennae when hunting. Their antennae are sensitive to both smells and tactile information. They use both their mandibles and their legs for holding prey. This way they ...

Soil organic matter (SOM) cycling has significant consequences for ecosystem processes and functioning. Studies of SOM have focused traditionally on soil microorganisms that regulate the fundamental biochemical processes of litter mineralization and organic matter formation. However, microbe-mediated processes rarely occur in isolation in natural systems without the involvement of soil fauna. Nevertheless, little attention has been paid to soil fauna - e.g., the direct roles they play in SOM cycling, and indirect roles through changing microbial community composition, activity, and function to influence soil C and N dynamics. We combine traditional morphological characterization of soil invertebrates with microbial functional assays, and modern chemical techniques to identify relationships among soil fauna, microbe, plant residue inputs, and SOM. Our ultimate goal is to investigate whether/how soil fauna contribute to soil organic carbon storage, especially through their impacts on microbial ...

Abstract. Thousands of arthropod species, ranging from arachnids (spiders and scorpions) to hymenopterans (ants, bees, and wasps) and myriapods (centipedes), are venomous and use their venoms for both defense and predation. These venoms are invariably harmful to humans, and some may cause serious injuries, e.g., those from scorpions, spiders, and wasps. Arthropods venoms are also known as rich sources of biologically active compounds and have attracted the attention of toxin researchers for years. In this century, venom component analysis has progressed considerable due to the advances in analytical techniques, in particular, mass spectrometry and next-generation deep (DNA and RNA) sequencing. As such, proteomic and peptidomic analyses using LC-MS have enabled the full analysis of venom components, revealing a variety of novel peptide and protein toxins sequences and scaffolds, potentially useful as pharmacological research tools and for the development of highly selective peptide ligands and ...

The springtails (Collembola) species collected include Desoria klovstadi, Fresia grisea, Cryptopygus cisantarcticus, Gomphiocephalus hodgsoni, Antarctophorus sudpolaris, Biscoia subpolaris and Neocryptopygus nivicolis. The mite (Acari) species collected were Stereotydeus mollis and Nanorchestes spp. Some genetic work was completed on one species of nematode Scottnema lindsayae from Mt Kyffin Traditional, morphologically-based, taxonomic approaches for assessing biodiversity were combined with more recent molecular techniques (e.g. allozyme and DNA analyses) with individuals from each study site evaluated using protein electrophoresis, mtDNA and morphological analyses. Allozyme electrophoresis was used to determine genetic differences within and among populations. Genotype frequencies were recorded for each locus at each site. Detailed and quantitative observations were made on modes of dispersal through the use of windsocks, pitfall traps and stream drift nets. These analyses are designed to ...

The Crustacea are a subphylum of arthropods with 67,000 described species. They are part of the phylum Arthropoda. Crustaceans include crabs, lobsters, crayfish, shrimp, krill and barnacles. They are relatives of insects. If the Arthropods are regarded as a superphylum, then the insects and crustacea would be phyla. (see List of animal phyla). The group has an extensive fossil record, reaching back to the Cambrian. Most crustaceans are aquatic, mostly marine. Some have moved onto land permanently. Crustaceans that live on land include some crabs, and woodlice. Crustacea range in size from a parasite 0.1mm long, to the Japanese spider crab with a leg span of up to 14 ft (4.3 m) and a mass of 44 lb (20 kg). The North Atlantic lobster can weigh more than 40 pounds. Most crustaceans are mobile, but some become sessile after their larval stage. Barnacles become attached to rocks on the sea shore. Some are parasitic, like fish lice, and tongue worms. Crustacea usually have separate sexes, and the eggs ...

Oilseed rape (Brassica napus) is an important combinable break crop in the UK, which is largely protected from arthropod pests by insecticidal chemicals. Despite ongoing debate regarding the use of neonicotinoids, the dominant seed treatment ingredients used for this crop, there is little publicly available data comparing the efficacy of insecticides in controlling key arthropod pests or comparing the impacts on non-target species and the wider environment. To provide an insight into these matters, a UK-wide expert survey targeting agronomists and entomologists was conducted from March to June 2015. Based on the opinions of 90 respondents, an average of 20% yield loss caused by the key arthropod pests was expected to have occurred in the absence of insecticide treatments. Relatively older chemical groups were perceived to have lower efficacy for target pests than newer ones, partly due to the development of insecticide resistance. Without neonicotinoid seed treatments, a lack of good ...

A survey of natural enemies and their associated arthropod preys/hosts occurring in the pomegranate orchards in Antalya province (South-western part of Turkey) was carried out during the years, 2011 and 2012. Samples were collected by aspirator, hand picking with a fine forceps or a fine brush for tiny arthropods and beating/jarring of vegetation. Additionally, small and medium sized branches infested with arthropod pests were collected for subsequent close examination or rearing of immature stages of some predators. Pest-infested plant samples containing parasitoids were also collected to obtain adult parasitoids in emergence boxes. All the collected samples were taken to the laboratory and separated soon after each sampling. The results from the study revealed that 22 species of predators (Coleoptera - Coccinellidae: 13; Hemiptera - Anthocoridae: 2, Nabidae: 2; Neuroptera - Chrysopidae: 2; Dermaptera - Forficulidae: 1; Thysanoptera - Thripidae: 1 and Acarina - Phytoseiidae: 1) and 2 species of ...

Abstract The possibility of vaccinating hosts against blood-feeding arthropods using antigens derived from salivary gland, gut, and other tissues is reviewed. These vaccines directed against vector arthropods also have the potential to effect the arthropods capacity to transmit pathogens, and this is distinct from transmission-blocking vaccines that use antigens derived from pathogens. Antigen extracts have been used in attempts to vaccinate against fleas, lice, keds, flies, mosquitoes, and a number of tick species. A vaccine against the cattle tick, Boophilus microplus (Canestrini), using a recombinant antigen, has been tested under field conditions. Ticks feeding on vaccinated hosts are damaged by an immune response directed against their gut cells. Some die on the host, others engore but their fecundity is reduced. The Commonwealth Scientific Industrial Research Organization-Biotechnology Australia tick vaccine against B. microplus is cited as a model for the development of other vaccines. It is

Maxillopoda. Ostracoda. Malacostraca. Crustaceans (Crustacea) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 50,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates by the possession of biramous (two-parted) limbs, and by the nauplius form of the larvae.. Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive fossil record, reaching back to the Cambrian, and includes living fossils such as Triops cancriformis, which ...

Wolbachia are a group of cytoplasmically inherited bacteria that cause reproduction alterations in arthropods, including parthenogenesis, reproductive incompatibility and feminization of genetic males. Two major subdivisions of Wolbachia (A and B) occur. Wolbachia are found in a number of well-studied insects, but their overall distribution in arthropods has not been well studied. A survey for Wolbachia in 157 Panamanian neotropical arthropod species was done using a polymerase chain reaction assay. Wolbachia were detected in 26 of 154 insect species (16.9%) and zero of three arachnids (0%). Extrapolating to the estimated total number of insect species present globally (10-30 million), an estimated 1.69-5.07 million insect species are infected with these bacteria, making Wolbachia an extremely abundant bacterial group. Wolbachia were found in each of the major insect orders examined, including Coleoptera (6/57 infected), Diptera (5/14), Hemiptera/Homoptera (1/7), Hymenoptera (6/23) Lepidoptera ...

Numerous studies have recently reported on the discovery of bee viruses in different arthropod species and their possible transmission routes, vastly increasing our understanding of these viruses and their distribution. Here, we review the current literature on the recent advances in understanding the transmission of viruses, both on the presence of bee viruses in Apis and non-Apis bee species and on the discovery of previously unknown bee viruses. The natural transmission of bee viruses will be discussed among different bee species and other insects. Finally, the research potential of in vivo (host organisms) and in vitro (cell lines) serial passages of bee viruses is discussed, from the perspective of the host-virus landscape changes and potential transmission routes for emerging bee virus infections.

When choosing a pesticide, the landscaper should select a product that is specific to the pest to be controlled in order to spare beneficial arthropods. Systemic insecticides are less likely to affect predators and parasites on plant surfaces. Insecticidal soaps may spare hard bodied predaceous or parasitic arthropods. Microbial insecticides such as Bacillus thuringiensis products (Dipel®, Thuricide® and others) are target-specific for certain groups of insects. Specific miticides generally spare other arthropods.. Care must also be taken when using pesticides other than insecticides and miticides. Certain fungicides such as Benlate® will affect insectivorous fungi and other non-target organisms. Broad-spectrum insecticides often are useful when more than one pest is present, but they may cause a rapid resurgence of the primary or secondary pest. Pyrethroid insecticides can be more harmful to parasitic wasps than to the pests listed on their labels and may result in secondary pest outbreaks. ...

The European Union (EU) is facing the recent arrival of the bacterium Xylella fastidiosa. Its fast spread has caused great alarm because of the economic impact it implies for the agroeconomy of European countries. Among its insect vectors, Philaenus spumarius has been demonstrated to transmit the bacterium from infected to uninfected trees in the EU, where different measures have been established to control it. One of the proposals to manage this vector is the augmentation of natural enemy populations. However, the identification of candidate predator species is essential if such a management system is to be introduced. The present paper describes a set of species-specific primers designed to detect the presence of P. spumarius DNA in soil arthropod fauna generalist predators’ gut which can reveal candidate species for the pest’s biological control. Such primers have been proven to be a useful and reliable taxonomic tool for P. spumarius identification at any life stage, i.e., nymphs. This

More generally, we are looking on the susceptibility of different stages of these arthropod vectors to microbials particularly fungi and also looking on the effects of botanicals against mosquitoes and ticks.. ...

The Center conducts research on insects of agricultural, medical and veterinary importance with the goal of achieving control of pest species through the development of environmentally acceptable approaches. Emphasisis placed on developing components and systems for integrated pest management, based upon an understanding of the behavior, physiology and ecology of pest species. Sensitive detection devices that employ semio-chemicals and electronic technology will provide the means for early intervention. Investigations will lead to biological control based on parasites, predators and microbes, and thus provide alternative, bio-rational tools for managing populations of pest species. Special attentionis focused on insect pests of field & horticultural crops, stored products and on arthropod pests of medical and veterinary importance. Protection of humans from arthropods of medical importance is a continuing priority. Thescope of the Centers research is national and international and impacts ...

The Medical Entomology Project (MEP), a cooperative venture between the Smithsonian Institution and the U.S. Army Medical Research and Development Command, conducts biosystematic research on arthropods of medical importance to the Army. MEP fulfills these objectives by performing biosystematic studies on important groups of vectors such as anopheline vectors of malaria parasites and culicine vectors of arboviruses, providing information on potential vectors for the guidance of military field research teams and other governmental agencies and preparing monographs and technical papers which summarize data on the ecology, taxonomy and medical importance of arthropod vectors in various regions of the world. In addition, MEP performs curation and research on the national collection of mosquitoes at the National Museum of Natural History (USNM), Smithsonian Institution. Research continues on the arbovirus vector groups of the subgenus Stegomyia, genus Aedes, of the African Region.*Entomology

A plan to eliminate rats on Alcatraz, home to the famous old prison in San Francisco Bay, led to the discovery of an unfamiliar glowing creature never before seen on the island.

The Paleozoic era spanned from 540 to 252 million years ago (mya) and represents the first era of diverse, complex life on Earth. The name Paleozoic means ancient life. During the early Paleozoic era, many new groups of marine invertebrates (animals without backbones) dominated the earth, although primitive vertebrates (animals with backbones) also began to appear. As the Cambrian explosion continued, almost all of the major groups of modern animals evolved from shared common ancestors. The ancient world ocean brimmed with invertebrate animals such as sponges, corals, and crabs (Fig. 7.11 A) as well as the first vertebrate animals: fishes (Fig. 7.11 B). The first animals to begin to colonize dry land were likely arthropods (Fig. 7.11 C). Arthropods are a group of invertebrate animals with jointed arms and hard shells including crabs, shrimp, spiders, and insects. By the end of the Paleozoic era-almost 300 mya after the Cambrian explosion-arthropods, amphibians, and some primitive reptiles ...

Story continues with In The Newspaper (Part 2 of 5). If not for the badge pinned to his jeans pocket, no one would know the pony-tailed 20-something was a cop. This is detective Ed Burgess. Double-chinned Schofield, stained collar open and tie unknotted, gestured toward the newcomer. Judge Denton, Detective Ed Burgess. Burgess. Denton. Before extending a hand, the young Burgess removed mini headphones from deep within his ear canals. Pleasure, said Burgess. He stood, despite the empty chair next to Denton. It was understandable. First, the thrift shop condition of the chair wasnt too inviting and second, the judge looked like hell after the ordeal. Remarkable transformation, calculated Burgess. The judge had left his house earlier that morning, no doubt looking sharp and crisp, ready to do whatever judges do. Now, he appeared worse than shit. Burgess had dealt with down and out crack addicts who looked and smelled better.. Schofield spoke between thick lips. Judge, this has got to be ...

Mandibles are also crucial to the hunting success of predatory ants. Mandibles can be wielded as formidable weapons in their own right, or as tools with which to grasp prey until a paralyzing sting can be delivered (a common strategy in the Ponerinae, most of which are solitary predators). Mass foraging predators (e.g. army ants, described below) use their mandibles to pin down prey from all sides while their nestmates dispatch it. A number of highly modified mandibles have evolved in response to the requirements of catching certain prey, especially those that are otherwise difficult to catch (e.g. collembolans). See the section on specialized predators below for several examples of such modifications. Despite a common misconception, most ants lack painful bites (being too small to have any effect on human skin). Usually ant bites are actually the venomous stings of ants in certain subfamilies (most commonly the Myrmicinae, but also members of the Ponerinae, Myrmeciinae, Pseudomyrmecinae, and ...

De oermûnigen (Latynske namme: Protostomata of Protostomia) foarmje in boppestamme fan it ryk fan e dieren (Animalia), it ûnderryk fan e echte dieren (Metazoa), it tuskenryk fan e twasidigen (Bilateria) en de rangleaze groep fan e termdieren (Nephrozoa). Oermûnigen ûnderskiede har fan har sustergroep, de nijmûnigen (Deuterostomata), trochdat by de embryonale ûntwikkeling de earste lichemsiepening de mûle wurdt, wylst dat by de oermûnigen de anus wurdt (de lichemsiepening dyt him as twadde ûntwikkelet, ûntjout him by nijmûnigen ta de mûle). Dêrfandinne de wittenskiplike namme Protostomata of Protostomia, wat yn it Gryksk earste mûle bestjut. Ta de oermûnigen hearre û.m. de lidpoatigen (Arthropoda), de weakdieren (Mollusca), de rûnwjirms (Nematoda) en de platwjirmeftigen (Platyzoa). Fierwei de grutste groep binne de lidpoatigen, dêrt û.m. de ynsekten (Insecta), de spineftigen (Arachnida), de kreefteftigen (Crustacea), en de tûzenpoatigen (Myriapoda) ûnder falle. ...
