Ultrabithorax function in butterfly wings and the evolution of insect wing patterns. (1/1684)

BACKGROUND: . The morphological and functional evolution of appendages has played a critical role in animal evolution, but the developmental genetic mechanisms underlying appendage diversity are not understood. Given that homologous appendage development is controlled by the same Hox gene in different organisms, and that Hox genes are transcription factors, diversity may evolve from changes in the regulation of Hox target genes. Two impediments to understanding the role of Hox genes in morphological evolution have been the limited number of organisms in which Hox gene function can be studied and the paucity of known Hox-regulated target genes. We have therefore analyzed a butterfly homeotic mutant 'Hindsight', in which portions of the ventral hindwing pattern are transformed to ventral forewing identity, and we have compared the regulation of target genes by the Ultrabithorax (Ubx) gene product in Lepidopteran and Dipteran hindwings. RESULTS: . We show that Ubx gene expression is lost from patches of cells in developing Hindsight hindwings, correlating with changes in wing pigmentation, color pattern elements, and scale morphology. We use this mutant to study how regulation of target genes by Ubx protein differs between species. We find that several Ubx-regulated genes in the Drosophila haltere are not repressed by Ubx in butterfly hindwings, but that Distal-less (Dll) expression is regulated by Ubx in a unique manner in butterflies. CONCLUSIONS: . The morphological diversification of insect hindwings has involved the acquisition of different sets of target genes by Ubx in different lineages. Changes in Hox-regulated target gene sets are, in general, likely to underlie the morphological divergence of homologous structures between animals.  (+info)

Predicting insecticide resistance: mutagenesis, selection and response. (2/1684)

Strategies to manage resistance to a particular insecticide have usually been devised after resistance has evolved. If it were possible to predict likely resistance mechanisms to novel insecticides before they evolved in the field, it might be feasible to have programmes that manage susceptibility. With this approach in mind, single-gene variants of the Australian sheep blowfly, Lucilia cuprina, resistant to dieldrin, diazinon and malathion, were selected in the laboratory after mutagenesis of susceptible strains. The genetic and molecular bases of resistance in these variants were identical to those that had previously evolved in natural populations. Given this predictive capacity for known resistances, the approach was extended to anticipate possible mechanisms of resistance to cyromazine, an insecticide to which L. cuprina populations remain susceptible after almost 20 years of exposure. Analysis of the laboratory-generated resistant variants provides an explanation for this observation. The variants show low levels of resistance and a selective advantage over susceptibles for only a limited concentration range. These results are discussed in the context of the choice of insecticides for control purposes and of delivery strategies to minimize the evolution of resistance.  (+info)

The putative bioactive surface of insect-selective scorpion excitatory neurotoxins. (3/1684)

Scorpion neurotoxins of the excitatory group show total specificity for insects and serve as invaluable probes for insect sodium channels. However, despite their significance and potential for application in insect-pest control, the structural basis for their bioactivity is still unknown. We isolated, characterized, and expressed an atypically long excitatory toxin, Bj-xtrIT, whose bioactive features resembled those of classical excitatory toxins, despite only 49% sequence identity. With the objective of clarifying the toxic site of this unique pharmacological group, Bj-xtrIT was employed in a genetic approach using point mutagenesis and biological and structural assays of the mutant products. A primary target for modification was the structurally unique C-terminal region. Sequential deletions of C-terminal residues suggested an inevitable significance of Ile73 and Ile74 for toxicity. Based on the bioactive role of the C-terminal region and a comparison of Bj-xtrIT with a Bj-xtrIT-based model of a classical excitatory toxin, AaHIT, a conserved surface comprising the C terminus is suggested to form the site of recognition with the sodium channel receptor.  (+info)

The development and evolution of bristle patterns in Diptera. (4/1684)

The spatial distribution of sensory bristles on the notum of different species of Diptera is compared. Species displaying ancestral features have a simple organization of randomly distributed, but uniformly spaced, bristles, whereas species thought to be more derived bear patterns in which the bristles are aligned into longitudinal rows. The number of rows of large bristles on the scutum was probably restricted to four early on in the evolution of cyclorraphous Brachyceran flies. Most species have stereotyped patterns based on modifications of these four rows. The possible constraints placed upon the patterning mechanisms due to growth and moulting within the Diptera are discussed, as well as within hemimetabolous insects. The holometabolic life cycle and the setting aside of groups of imaginal cells whose function is not required during the growth period, may have provided the freedom necessary for the evolution of elaborate bristle patterns. We briefly review the current state of knowledge concerning the complex genetic pathways regulating achaete-scute gene expression and bristle pattern in Drosophila melanogaster, and consider mechanisms for the genetic regulation of the bristle patterns of other species of Diptera.  (+info)

Variability in spike trains during constant and dynamic stimulation. (5/1684)

In a recent study, it was concluded that natural time-varying stimuli are represented more reliably in the brain than constant stimuli are. The results presented here disagree with this conclusion, although they were obtained from the same identified neuron (H1) in the fly's visual system. For large parts of the neuron's activity range, the variability of the responses was very similar for constant and time-varying stimuli and was considerably smaller than that in many visual interneurons of vertebrates.  (+info)

A novel egg-derived tyrosine phosphatase, EDTP, that participates in the embryogenesis of Sarcophaga peregrina (flesh fly). (6/1684)

We have previously reported that cathepsin L mRNA is present in unfertilized eggs of Sarcophaga peregrina (flesh fly) as a maternal mRNA, which suggests that cathepsin L is required for embryogenesis. Now we have identified an egg protein, with a molecular mass of 100 kDa, that is extremely susceptible to cathepsin L digestion and which disappears rapidly as the embryos develop. We purified this protein to homogeneity, cloned its cDNA, and found that it contained a consensus sequence for the active site of tyrosine phosphatase. In fact this protein showed tyrosine phosphatase activity, indicating that it is a novel tyrosine phosphatase. The expression and subsequent disappearance of this protein, which we have named egg-derived tyrosine phosphatase (EDTP), may be indispensable for embryogenesis of Sarcophaga.  (+info)

An aural myiasis case in a 54-year-old male farmer in Korea. (7/1684)

A 54-year-old male farmer residing in Chunchon, Korea, complaining of blood tinged discharge and tinnitus in the left ear for two days, was examined in August 16, 1996. Otoscopic examination revealed live maggots from the ear canal. The patient did not complain of any symptoms after removal of maggots. Five maggots recovered were identified as the third stage larvae of Lucilia sericata (Diptera: Calliphoridae). This is the first record of aural myiasis in Korea.  (+info)

The planarian HOM/HOX homeobox genes (Plox) expressed along the anteroposterior axis. (8/1684)

In the freshwater planarian Dugesia japonica, five cDNAs for HOM/HOX homeobox genes were cloned and sequenced. Together with sequence data on HOM/HOX homeobox genes of platyhelminthes deposited in databases, comparison of the deduced amino acid sequences revealed that planarians have at least seven HOM/HOX homeobox genes, Plox1 to Plox7 (planarian HOM/HOX homeobox genes). Whole-mount in situ hybridization and RT-PCR revealed that Plox4 and Plox5 were increasingly expressed along a spatial gradient in the posterior region of intact animals. During regeneration, Plox5 was expressed only in the posterior region of regenerating body pieces, suggesting that the gene is involved in the anteroposterior patterning in planarians. Plox5 was not found to be expressed in a blastema-specific manner, which contradicts a previous report (J. R. Bayascas, E. Castillo, A. M. Munos-Marmol, and E. Salo. Development 124, 141-148, 1997). X-ray irradiation experiments showed that Plox5 was expressed at least in some cells other than neoblasts, but that the induction of Plox5 expression during regeneration might require neoblasts.  (+info)

Knowledge of karyotypical characteristics of a species is essential for understanding how sexually selected and sexually antagonistic traits evolve. The yellow dung fly Scathophaga stercoraria L. (Diptera: Scathophagidae) is an established model system for studies of sexual selection and sexual conflict, but karyotypical data are lacking to date. Here, the karyotype of S. stercoraria was characterized using conventional Giemsa-staining and C-banding techniques. The diploid chromosome set consists of 6 pairs of bi-armed meta- or submetacentric chromosomes. The sex chromosomes are the largest chromosomes and constitute 30% of the total length of the diploid set in females and about 25% in males. Males are the heterogametic sex, and the length of the Y chromosome is about three-quarters of that of the X chromosome. C-banding revealed that both sex chromosomes are largely heterochromatic. In contrast, in the five autosome pairs, heterochromatin is limited to narrow bands in the centromeric regions. ...

The species Lucilia cuprina, formerly named Phaenicia cuprina, is more commonly known as the Australian sheep blowfly. It belongs to the blow-fly family Calliphoridae, and while some authorities combine the blow flies (Calliphoridae) and the flesh flies (Sarcophagidae) together into the Metopiidae family, distinguishable characteristics allow for the separation. Lucilia cuprina is a member of the order Diptera, has a pair of short but very strong membranous wings and a pair of hindwings reduced and modified to clublike balancers known as halteres. This adaptation distinguishes the true flies (Diptera) from the other orders with fly in their name, and serves as a sensory aid that acts as tiny gyroscopes or inertial navigation system. The mesothorax is much enlarged while the prothorax and metathorax are reduced. Blow flies are about the size of a house fly or a little larger, and though considered to be nuisances indoors are essential agents in the breakdown of organic matter. Most are metallic ...
The developmental rate under low temperatures and cold tolerance were investigated in embryos of the blowfly Lucilia sericata. The larvae of this species are now widely used in maggot debridement therapy. Embryonic development was dependent on temperature, with a lower developmental threshold of 9.0 °C. The duration of the egg stage at a rearing temperature of 25 °C was 14 h, and a low temperature of 12.5 °C successfully prolonged this period to 66 h. Embryonic stages differed markedly in their cold tolerance; young embryos were less tolerant to cold than old ones. Late embryonic stages are suitable for cold storage at 5 °C and the storage for 72 h did not decrease the hatching rate by more than 50%. In the mass-rearing process required for maggot debridement therapy, either of these two simple protocols would be beneficial ...
Geometric wing morphometrics for Chrysomya albiceps and C. megacephala identification (Diptera: Calliphoridae) from Venezuela. Calliphoridae is one of the families with the greatest number of species with forensic importance, which immature stages feed and develop on decaying material. In Venezuela, there are few studies on this taxon reporting the dominance of Chrysomya over other carrion flies. The goal of this study was to analyze the variations on wing morphometrics, to support the identification of two forensic flies. For this we photographed a total of 168 wings from C. albiceps (n=111) and C. megacephala (n=57). Landmark coordinate (x, y) configurations were registered and aligned by Generalized Procrustes Analysis. Principal Component Analysis and shape significance test based on Procrustes distance were implemented. Statistical analysis of variance found significant differences in wing isometric size (Kruskal-Wallis). The PCA showed the separation between species, and shape test showed ...
When starting her own lab at James Cook University, Australia, Jodie Rummer applied for a Travelling Fellowship from JEB to gather data on oxygen consumption rates of coral reef fishes at the Northern Great Barrier Reef. A few years later, Björn Illing, from the Institute for Hydrobiology and Fisheries Science, Germany, followed in Jodies footsteps and used a JEB Travelling Fellowship to visit Jodies lab. There, he studied the effects of temperature on the survival of larval cinnamon clownfish. Jodie and Björns collaboration was so successful that they have written a collaborative paper, and Björn has now returned to continue his research as a post-doc in Jodies Lab. Read their story here.. Where could your research take you? The deadline to apply for the current round of Travelling Fellowships is 30 Nov 2017. Apply now!. ...
N-Formylation and N-methylation of the alpha-amino group of L-phenylalanine result in extremely decreased responses of the labellar sugar receptor of the fleshfly, whereas the same structural alteration of L-valine hardly affects the response. Methyl esterification of the alpha-carboxyl group of phenylalanine, on the other hand, maintains the response to some extent, but similar treatment of valine completely diminishes the response. The aromatic structure in phenylalanine is not essential for stimulation. These results suggest a substantial difference in the stereospecificities and functional group specificities of the furnase (F) and aliphatic carboxylate (T) sites in the sugar receptor. The effect of small peptides on the sugar receptor was examined systematically. Their effectiveness depends mainly on the place of the constituent amino acids rather than on their composition, indicating the decisive role that certain aliphatic amino acids in the C-terminal position play in stimulation. ...
This Test Guideline describes a method to estimate the developmental toxicity of a test chemical to the dung dwelling life stages of dung-dependent dipteran species. Two test species can be used. The test chemical is mixed with bovine faeces, to which either 10 eggs of Scathophaga stercoraria or 10 larvae of Musca autumnalis are added. The test will be terminated 5 days after emergence of the last adult in the control (> 18 days for S. stercoraria, >13 days for M. autumnalis). Then the possible impacts of the test chemical on the following measurement endpoints are assessed under controlled conditions: sex and total number of emerged adult flies, retardation of emergence indicated by the developmental rate and morphological change. Depending on the experimental design, the No Observed Effect Concentration (NOEC) or the Effect concentration for x percent effect (ECx) can be determined. This Guideline can be used for water soluble or insoluble substances, but is not

In arthropods like Drosophila, Down syndrome cell adhesion molecules (Dscam1) exhibit enormous molecular diversity. A single Dscam1 gene encodes a large superfamily of neuronal cell recognition proteins that control neuronal outgrowth and anatomy. A comparable function is exhibited by the vertebrates DSCAMs of which only few isoforms exist. However, it is largely unknown, if and how this function of Dscams affects neuronal function and the control of behavior by the nervous system. In this thesis, I employed an arsenal of genetic techniques to perturb the expression level of Dscam1 isoforms in directionally selective Lobula Plate Tangential Cells (LPTCs). LPTCs of the Vertical (VS) and the Horizontal System (HS) were chosen as a model system because of their well-documented anatomy, role in information processing and behavior. Though, only little is known about the developmental mechanisms and molecular factors controlling the morphogenesis and wiring of these cells. The central aim of my study ...
Fleece rot (FR) and body-strike of Merino sheep by the sheep blowfly Lucilia cuprina are major problems for the Australian wool industry, causing significant losses as a result of increased management costs coupled with reduced wool productivity and quality. In addition to direct effects on fleece quality, fleece rot is a major predisposing factor to blowfly strike on the body of sheep. In order to investigate the genetic drivers of resistance to fleece rot, we constructed a combined ovine-bovine cDNA microarray of almost 12,000 probes including 6,125 skin expressed sequence tags and 5,760 anonymous clones obtained from skin subtracted libraries derived from fleece rot resistant and susceptible animals. This microarray platform was used to profile the gene expression changes between skin samples of six resistant and six susceptible animals taken immediately before, during and after FR induction. Mixed-model equations were employed to normalize the data and 155 genes were found to be differentially

We report here the molecular and cytological characterization of two proteins, ScoHET1 and ScoHET2 (for Sciara coprophila heterochromatin), which associate to constitutive heterochromatin in the dipteran S. coprophila. Both proteins, ScoHET1 of 37 kDa and ScoHET2 of 44 kDa, display two chromodomain motifs that contain the conserved residues essential for the recognition of methylated histone H3 at lysine 9. We raised antibodies to analyze the chromosomal location of ScoHET1 and ScoHET2 in somatic and germline cells. In S. coprophila polytene chromosomes, both proteins associate to the pericentromeric regions and to the heterochromatic subterminal bands of the chromosomes. In germinal nuclei, ScoHET1 and ScoHET2 proteins distribute to the heterochromatic regions of the regular chromosome complement and are abundantly present along the heterochromatic germline-limited

The New World Screwworm fly, Cochliomyia hominivorax, is a major pest of livestock in South America and Caribbean. However, few genomic resources have been available for this species. A genome of 534 Mb was assembled from long read PacBio DNA sequencing of DNA from a highly inbred strain. Analysis of molecular evolution identified 40 genes that are likely under positive selection. Developmental RNA-seq analysis identified specific genes associated with each stage. We identify and analyze the expression of genes that are likely important for host-seeking behavior (chemosensory), development of larvae in open wounds in warm-blooded animals (heat shock protein, immune response) and for building transgenic strains for genetic control programs including gene drive (sex determination, germline). This study will underpin future experiments aimed at understanding the parasitic lifestyle of the screwworm fly and greatly facilitate future development of strains for efficient systems for genetic control of
Several physiological mechanisms allow sensory information to be propagated in neuronal networks. According to the conventional view of signal processing, graded changes of membrane potential at the dendrite are converted into a sequence of spikes. However, in many sensory receptors and several types of mostly invertebrate neurons, graded potential changes have a direct impact on the cells output signals. The visual system of the blowfly Calliphora vicina is a good model system to study synaptic transmission in vivo during sensory stimulation. We recorded extracellularly from an identified motion-sensitive neuron while simultaneously measuring and controlling the membrane potential of individual elements of its presynaptic input ensemble. The membrane potential in the terminals of the presynaptic neuron is composed of two components, graded membrane potential changes and action potentials. To dissociate the roles of action potentials and graded potential changes in synaptic transmission we used ...
Heat stress exerts a profound impact on the resistance of plants to parasites. In this research, we investigated the impact of an acute transient heat stress on the resistance of the wheat line Molly, which contains the R gene H13, to an avirulent Hessian fly (Mayetiola destructor (Say)) population. We found that a significant portion of Molly seedlings stressed at 40°C for 6 h during or after the initial Hessian fly larval attack became susceptible to otherwise avirulent insects, whereas unstressed control plants remained 100% resistant. Specifically, 77.8,73.3,83.3, and 46.7% of plants heat stressed at 0,6,12, and 24 h, respectively, after the initial larval attack became susceptible. Biochemical analysis revealed that heat stress caused a transient decrease in 12-oxo-phytodienoic acid, but an increase in salicylic acid accumulation in Molly plants. The change in phytohormones after heat stress and Hessian fly infestation was not observed in Newton, a near-isogenic but Hessian fly ...

Chrysomya megacephala, more commonly known as the oriental latrine fly, is a member of the family Calliphoridae (blowflies). It is a warm-weather fly with a greenish-blue metallic box-like body. The fly infests corpses soon after death, making it important to forensic science. This fly is implicated in some public health issues; it can cause accidental myiasis, and also infects fish and livestock. C. megacephalas eggs are oval with one flat face and another convex. Adult flies reflect a metallic blue-green color on their thorax and abdomen and have yellow gena, or cheeks. Larvae vary in size according to instar and are shaped more thickly towards the rear. C. megacephala have large red eyes, those of males being close together, and those of females farther apart. The cercus of the male is longer than that of the female. Chrysomya megacephala has a wide geographical distribution. It is most common in the Oriental region and Australasia. It is also found in Japan and the Palearctic region. The ...

Flies are highly visually guided animals. In this thesis, I have used hoverflies as a model for studying motion vision. Flies process motion vision in three visual ganglia: the lamina, the medulla, and the lobula complex. In the posterior part of lobula complex, there are around 60 lobula plate tangential cells (LPTCs). Most of LPTCs have large receptive fields where the local direction sensitivity suggests that they function as matched filters to specific types of optic flow. LPTCs connect to descending or neck motor neurons that control wing and head movements, respectively. Therefore, in this thesis I have focused on the electrophysiological responses of LPTCs to gain understanding of visual behaviors in flies.. The elementary motion detector (EMD) is a model that can explain the formation of local motion sensitivity. However, responses to higher order motion, where the direction of luminance change is uncorrelated with the direction of movement, cannot be predicted by classic EMDs. ...
Throughout the Metazoa sperm are evolutionarily labile and diverge rapidly, exhibiting a bewildering array of morphological specializations (reviewed by Pitnick et al. 2009a). Although understanding of the adaptive significance of variation in sperm form is meager, post-copulatory sexual selection, occurring through competition to fertilize ova, is widely regarded as the primary agent for sperm diversification (reviewed by Pitnick et al. 2009b; Pizzari & Parker 2009). Recent theoretical treatments of sperm adaptation, with a focus on sperm conjugation and heteromorphism, have postulated roles of kin selection and multi-level selection (Immler 2008; Pizzari & Foster 2008; Pizzari & Parker 2009). Sperm conjugation occurs when two or more sperm physically unite to enhance motility and/or transport through the female reproductive tract, with sperm typically disassociating from one another only after reaching the site of sperm storage or fertilization (reviewed by Immler 2008; Pitnick et al. 2009a). ...

Proper identification of the Common Green Bottle Fly requires two characteristics. These two aspects of the bottle fly are important because the Common Green Bottle Fly is almost identical to its sister species, the Lucilia cuprina. In fact, microscopic examination is needed to tell the two species apart. The first main characteristic of the Common Green Bottle Fly is the presence of three bristles on the dorsal mesothorax. This body region is located on the middle of the back of the fly and can be most used when identifying the adult life stage of the fly. The Common Green Bottle Fly has 6-8 bristles on each side while Lucilia cuprina have only one. The second identifying characteristic is found when looking at the femoral joint in the first pair of legs. When looking at the Lucilia cuprina species, the femoral joint is metallic green. Rather, when investigating the Common Green Bottle Fly, this joint is a blue-black color ...
Dear All, The flies (Order Diptera) are a cladists dream. Certainly NOT because it is all that easy to study their phylogeny, but rather because it is more pectinate (asymmetric) in its evolution than most groups. This makes the group one that is ideal for total cladification (which should make strict cladists very happy). However EVEN in this case, whether it should be totally cladified depends on your philosophic leanings. Therefore, in this case I am presenting two identical phylogenies of Diptera, one with limited paraphyly and other with no apparent paraphyly at all (holophyly only). However, it is just my first attempt at classifying Order Diptera to family level, so the coding is obviously going to be particularly preliminary. The placement of Tanyderidae and Ptychopteridae at the base of Diptera is rather unusual (rather than Tipulidae), but it seems a viable option to me at the present time, so Im taking the opportunity to introduce this possibility (pushing the envelope or playing ...

Series of concentrations of 15 aliphatic alcohols were presented in 0.1 M sucrose to the tarsi of antennectomized-labellectomized blowflies (Phormia regina Meigen). With the pri-n-alcohols the mean concentrations at rejection formed a Traube series. When the rejection thresholds for all the alcohols tested were compared with their boiling points, vapor pressures, molecular surface areas) molecular moments, water-cottonseed oil distribution coefficients, standard free energies, and activity coefficients, a very high degree of correlation was found in each case. It is concluded that the limiting process which was measured is concerned with the receptor cells rather than with some other element in the complex response. Stimulative power was evidently not dependent on osmotic pressure nor on rate of molecular diffusion in solution, and the correlation with vapor pressure was inverse. It is judged that surface energy relationships are concerned in stimulation, but the exact mechanism cannot be ...

Background and Objective: The Mediterranean fruit fly (Medfly) Ceratitis capitata (Diptera: Tephritidae), as most of the Tephritidae species, is a pest of great economic importance around the world. Volatile organic compounds (VOC) emitted by Ceratitis capitata (C. capitata) at different life stages (larvae, pupae and adults) can help us to understand the chemicals they produce when interacting. This study aimed to use GC-MS technique to determine the optimal method for accurate, rapid and cost-effective of extraction of VOC from different life stages of C. capitata. Methodology: This study used HS-SPME fibre coupled with flame ionization detection (FID) and gas chromatography with mass spectrometry (GC-MS) to determine the optimal method for accurate, rapid and cost-effective of extraction of VOC from different life stages of C. capitata. Qualitative Analysis software was used to analyse retention times and peak areas. Data were then analyzed by using SPSS. Results: Results indicated that a 4 h ...
We have isolated the clock gene period (per) from the medfly Ceratitis capitata, one of the most economically important insect pest species. The overall pattern of conserved, non-conserved and functional domains that are observed within dipteran and lepidopteran per orthologues is preserved within the coding sequence. Expression analysis from fly heads revealed a daily oscillation in per mRNA in both light : dark cycles and in constant darkness. However PER protein levels from head extracts did not show any significant evidence for cycling in either of these two conditions. When the Ceratitis per transgene under the control of the Drosophila per promoter and 3UTR was introduced into Drosophila per -null mutant hosts, the transformants revealed a low level of rescue of behavioural rhythmicity. Nevertheless, the behaviour of the rhythmic transformants showed some similarities to that of ceratitis, suggesting that Ceratitis per carries species-specific information that can evidently affect the ...
Thirsty blowflies whose tarsi come into contact with water will respond with proboscis extension. When flies were exposed to high or low relative humidities (RH) prior to testing, the tarsal taste thresholds to sucrose in flies that were unresponsive to water alone increased or decreased, respectively. Evidently, thirst can also be subthreshold and recognizable only as a change in threshold to aqueous sucrose.. Thresholds to sucrose and fructose, which were in the millimolar range in 3-day-old adult flies held at 55-70% RH prior to testing, fell significantly after the flies had been held at low humidity (13-20% RH) for several hours. There was no low-humidity-dependent drop in threshold with galactose or xylose, sugars to which flies normally have thresholds in the 102mmoll−1 range.. Flies held at low relative humidity exhibited increased tarsal thresholds to sucrose when they were injected with water or were allowed to drink water adlibitum. When multiple injections of water were given, ...
Screwworm is important to both human and veterinary medicine due to its zoonotic potential. Before the eradication program, C. hominivorax caused significant production losses in livestock in the United States and Mexico. The eradication program launched in 1957 by releasing sterile flies to the areas with screwworm populations. Since then, screwworm has been eliminated in most areas north of Panama, including the United States and Mexico. Since eradication, the causes of screwworm myiasis in the United States have been related to the importation of improperly inspected animals. In September 2016, the USDA confirmed the presence of C. hominivorax in Key deer in Big Pine Key, Florida. Further investigation revealed that veterinarians diagnosed several domestic animals with unusual myiasis in the months prior. None of the cases of myiasis in domestic animals were reported. Authorities are not certain how screwworm was re-introduced to this area. During this time, all animals entering and exiting ...
Objective To explore ways of controlling Chrysomya putoria, the African latrine fly, in pit latrines. As pit latrines are a major source of these flies, eliminating these important breeding sites is likely to reduce village fly populations, and may reduce the spread of diarrhoeal pathogens. Methods We treated 24 latrines in a Gambian village: six each with (i) pyriproxyfen, an insect juvenile hormone mimic formulated as Sumilarv® 0.5G, a 0.5% pyriproxyfen granule, (ii) expanded polystyrene beads (EPB), (iii) local soap or (iv) no treatment as controls. Flies were collected using exit traps placed over the drop holes, weekly for five weeks. In a separate study, we tested whether latrines also function as efficient flytraps using the faecal odours as attractants. We constructed six pit latrines each with a built-in flytrap and tested their catching efficiency compared to six fish-baited box traps positioned 10 m from the latrine. Focus group discussions conducted afterwards assessed the ...

Interpretive Summary: The creation of transgenic strains of economically important insects for the development of more effective biological control programs is a major goal of our laboratory at CMAVE. The primary type of biocontrol is the sterile insect technique (SIT) which has been highly effective in controlling tephritid fruit fly pests, and animal pests such as the New World screwworm (NWS), Cochliomyia hominivorax. This paper describes research performed under the auspices of the FAO/IAEA Coordinated Research Project on Enabling technologies for the expansion of SIT for old and new world screwworm that involved the use of insect transgenesis technology, originally developed for tephritid flies, in NWS to improve SIT. The first transformation experiments were highly successful, resulting in eight ...
Defensins are the most widespread antimicrobial peptides characterised in insects. These cyclic peptides, 4-6 kDa in size, are folded into α-helical/β-sheet mixed structures and have a common conserved motif of three intramolecular disulfide bridges with a Cys1-Cys4, Cys2-Cys5 and Cys3-Cys6 connectivity. They have the ability to kill especially Gram-positive bacteria and some fungi, but Gram-negative bacteria are more resistant against them. Among them are the medicinally important compounds lucifensin and lucifensin II, which have recently been identified in the medicinal larvae of the blowflies Lucilia sericata and Lucilia cuprina, respectively. These defensins contribute to wound healing during a procedure known as maggot debridement therapy (MDT) which is routinely used at hospitals worldwide. Here we discuss the decades-long story of the effort to isolate and characterise these two defensins from the bodies of medicinal larvae or from their secretions/excretions. Furthermore, our previous studies

Background: Maggot therapy utilizes freshly emerged, sterile larvae of the common greenbottle fly, Phaenicia (Lucilia) sericata which secrete digestive enzymes that selectively dissolve necrotic tissue, disinfect the wound, and thus stimulate wound healing. Introduction: The purpose of this paper was to review the literature in an attempt to determine the efficacy of maggot debridement therapy (MDT) of skin ulcers (e.g. diabetic foot ulcers, venous stasis, osteomyelitis), with specific focus on assessing the healing time and amputation rate. Methodology: Efficacy was measured by comparing MDT to traditional treatment (i.e., antibiotics and surgical debridement). Level of evidence included case-control, cohort retrospective, retrospective, prospective control, non-randomized in-vivo, and report studies. Results: Overall results of the thirteen articles that met the inclusion criteria indicate that MDT healing time was equal to or significantly shorter and amputation rate was less than traditional ...

C. hominivorax can be distinguished from other myiasis-causing buggies by a travelers history and by its propensity to lay hundreds of eggs. Other awful flies that take this lets-infest-this-human route include the human botfly, Dermatobia hominis, and the tumbu fly, Cordylobia anthropophaga (another eater of man, incidentally), which tend to lay a single larva in a wound or lesion (3). C. hominivorax is the nastier bug of the three: it has cutting jaws that it uses to drill down to bone and nerves, and enter the bloodstream, necessitating the use of imaging technologies such as CAT scans and MRIs to see the extent of larval migration and proximity to vital structures (1). The infestation and resulting infections and abscesses can be deadly; it has a known 8% mortality rate (4).. (In an extraordinarily clever move, the US agricultural office dealt with the issue of screwworms in the American South by sterilizing the males with radiation and then releasing them to mate unprofitably with ...
RESUMO. Foram examinados os hemócitos de larvas do 2º (L2) e 3º(L3) instares de Dermatobia hominis em nível de microscopia óptica e comparados com os de outras espécies encontradas na literatura. Nas L2 e em L3 com peso de até 200mg foram encontrados cinco tipos: Pro-hemócitos, Plasmatócitos, Vermiformes, Oenocitóides e Esfoliativas. A medida em que as L3 foram-se tornando mais idosas apareceram em seqüência os Granulócitos e Adipohemócitos, sendo raro encontrar-se Pro-hemócitos em L3 com peso acima de 500mg. Tipos intermediários entre Pro-hemócitos e Plasmatócitos e entre Granulócitos e Adipohemócitos também foram encontrados, fazendo-se supor que pro-hemócitos dão origem ao Plasmatócito e que este dá origem ao Granulócito que pode acumular grãos de lipídeos transformando-se em Adipohemócito. O Oenocitóide parece ter origem diferente dos demais tipos. Não foram encontradas formas transicionais entre Plasmatócito fusiforme e Vermiforme típica conforme aparece na ...

Patient with 20 year history of an ulcer on his ankle. Maggot debridement therapy is a safe and very effective method for treating poorly healing wounds.. Here is an example of an ulcer on the ankle of a 59 year old man. He came into my practice after consulting many other doctors who had prescribed antibiotics or who diagnosed it as a venous stasis ulcer.. The patient first developed a wound on the medial malleolus of his right ankle when he was a young child riding in the basket of a bicycle. The medial malleolus is the protruding part on the inside of the ankle which is part of the tibial bone. The spokes of the bicycle wheel broke as his foot was trapped so the injury was severe. Eventually, this wound healed with a silver colored scar and did not bother him for about 30 years.. However, when he was in his early forties he hit his ankle with a piece of wood and developed another wound. It was not at the same location as his childhood injury but it was more proximal (3-4 inches towards the ...
Abstract The botanical compound allyl isothiocyanate (AITC) is toxic to many microorganisms and insects. The aim of this study was to assess the effects of AITC on the Bradysia odoriphaga Yang et Zhang (Diptera: Sciaridae) and the seeds and seedlings of the Chinese chive. Allyl isothiocyanate was toxic to all four developmental stages of B. odoriphaga. The adult was significantly more sensitive to AITC than the other three stages, which exhibited no significant differences to one another in sensitivity to the chemical. The control efficacy of AITC against B. odoriphaga was far superior in the greenhouse than the field. In addition, seedling survival was higher in the greenhouse compared with that in the field. In the absence of B. odoriphaga, seed germination and seedling growth of Chinese chives were inhibited by 16 µl/liter of AITC, and significant inhibition occurred under higher doses of AITC. These results indicate that AITC could be used to control B. odoriphaga during cultivation of Chinese

Biology of flies and maggots. Maggots are fly larvae, or immature flies, just as caterpillars are butterfly or moth larvae. Maggots do not appear all by themselves (de novo), as was believed 150 years ago; they hatch from eggs, laid by adult female flies.. Those flies whose larvae feed on dead animals will sometimes lay their eggs on the dead parts (necrotic or gangrenous tissue) of living animals. When maggots are infesting live animals, that condition is called myiasis. Some of those maggots will feed only on dead tissue, some only on live tissue, and some on live or dead tissue. The flies used most often for the purpose of maggot therapy are blow flies (Calliphoridae); and the species used most commonly is Phaenicia sericata, the green blow fly.. Current status of maggot therapy. In 1995, a handful of doctors in 4 countries were using MDT. Today, any physician in the U.S. can prescribe maggot therapy. Over 4,000 therapists are using maggot therapy in 20 countries. Approximately 50,000 ...
Chrysomya Robineau-Desvoidy (Diptera: Calliphoridae) is a genus of blowfly commonly observed in tropical and subtropical countries of the Old World. Species in this genus are vectors of bacteria, protozoans and helminths, cause myiasis, are predators of other carrion insects, and are important forensic indicators. Hypotheses concerning the evolution of sex determination, larval anatomy and genome size in Chrysomya have been difficult to evaluate because a robust phylogeny of the genus was lacking. Similarly, the monophyly of subgenera was uncertain. The phylogeny of Chrysomya spp. was reconstructed based on 2386 bp of combined mitochondrial cytochrome oxidase subunit I (COI) and nuclear carbamoylphosphate synthetase (CPS) genes. Maximum parsimony (MP), maximum likelihood (ML) and Bayesian analysis (BA) differed only slightly in the resulting tree topology. Chrysomya was monophyletic. Monogenic reproduction is almost certainly derived rather than, as has been suggested, primitive within the ...
The North American Screwworm fly (Cochliomyia hominivorax) is a Dipteran parasite of mammals, including humans and cattle. The eggs are laid in open wounds, and the screwworm larvae that hatch out eat the necrotic tissue, which can cause severe illness (myiasis) or death to the host. Eradication measures have included large-scale release of sterile male flies, and identification of insecticide-resistance genetic markers. As there are multiple strains of screwworms, biochemical markers can be used to identify which strains are present in a particular area ...

Attraction and Electroantennography responses of the male Mediterranean Fruit Fly, Ceratitis capitata, to natural essential oils and synthetic blends.. Meeting Abstract. Annual Meeting of the Entomological Society of America Nov 11-14, 2012. Interpretive Summary: Field experiments and long range bioassays were used to understand the difference in attractiveness among various natural essential oils for the Mediterranean Fruit Fly, Ceratitis capitata. Using electroantennography, we have selected various antennally active chemicals and tested their role in the attraction of the male. Choice combinations between various blends and modified essential oils underlined the role of mono and sesquiterpenes in the male attraction. The blends composed with EAD active synthetic chemicals lost their attractiveness when a specific monoterpene was absent, and the attractiveness of ginger root oil and manuka oil were increased when this chemical ...
Who really uses maggot therapy, anyway?. Today, nearly 4,000 therapists in 40 countries use maggot therapy; 700 in the U.S. alone. In 2006, an estimated 45,000 treatments were distributed world-wide. Is maggot therapy regulated by the FDA?. Yes, production and marketing of medicinal maggots is regulated by the Food and Drug Administration as a prescription only medical device. In January 2004, the U.S. Food and Drug Administration granted permission to Dr. Ronald Sherman to produce and market medicinal maggots, for the following indications: Debriding non-healing necrotic skin and soft tissue wounds, including pressure ulcers, venous stasis ulcers, neuropathic foot ulcers, and non-healing traumatic or post surgical wounds. Does insurance or Medicare cover maggot therapy?. Most private and public third-party payers of health care (insurance) will cover the cost of maggot therapy and medicinal maggots. But the person who first reviews the paperwork may not yet know that. If coverage is denied ...
The ZSM Diptera collection contains around 12,500 determined species (see lists of families, species, types), representing about 10% of the worlds scientifically described fly fauna. About 1,250 species are represented by type material. Additionally, there are large amounts of material still awaiting conclusive analysis. In the dry collection the core families are Asilidae, Bombyliidae, Conopidae, Diopsidae, Dolichopodidae, Leptogastridae, Limoniidae, Mycetophilidae, Pantophthalmidae, Stratiomyidae, Syrphidae, Tabanidae, Tachinidae, Tephritidae, and Tipulidae. The ZSMs special collection of Chironomidae (non-biting midges) includes about 60 000 microscope slides, making it one of the largest and most important of its kind. Another major part of the Diptera Section is the extensive alcohol collection, with the Chironomidae, Limoniidae and Mycetophilidae particularly well represented in terms of determined material. In addition, it contains much highly valuable yet incompletely studied material ...

Calling male field crickets (Gryllus spp.) are acoustically located and subsequently parasitized by the parasitoid fly, Ormia ochracea (Diptera: Tachinidae). Parasitism by O. ochracea results in cricket death. The reproductive compensation hypothesis posits that when a hosts residual reproductive value decreases, it would be adaptive for that host to shift its resources into current reproduction. Reproductive compensation has not been observed in the cricket-fly system. Here we review the studies to date that have investigated reproductive compensation in the cricket-fly interaction, in an attempt to understand why crickets do not compensate for their future reproductive losses. We conclude that the cricket-fly interaction may not be an ideal system in which to investigate reproductive compensation and furthermore, that reproductive compensation has been poorly investigated in this system.. ...
Orobanche species are parasitic weeds that subsist on the roots of many dicotyledonous plants. These parasites form symplastic and apoplastic connections with their hosts and act as strong sinks for the uptake of water, minerals, and photosynthates, often causing severe damage to the hosts. Although the uptake of small molecules such as sugars and herbicides by Orobanche has been documented, movement of macromolecules between host and parasite has not been characterized. The objectives of this research were to 1) determine whether, and by what route, host macromolecules can be translocated to the parasite, and 2) engineer host resistance based on inducible expression of sarcotoxin IA, an anti-microbial peptide from the flesh fly (Sarcophaga peregrina). To address the first objective, transgenic plants expressing GFP localized to either the host cell cytosol (symplast) or secreted to the extra-cellular space (apoplast) were parasitized by O. aegyptiaca. Observations of green fluorescence in O. ...

1. In 2002 Microdon myrmicae, a social parasite of Myrmica ants, was taxonomically separated from Microdon mutabilis. The original study in the U.K. found Microdon myrmicae to be specific to one ant species, Myrmica scabrinodis, yet it became apparent that the range of Microdon myrmicae includes at least the western Palaearctic. 2. Current knowledge of the European distributions of both Microdon myrmicae and Microdon mutabilis in Europe is reviewed. Also, in detailed studies of two Polish populations, Microdon myrmicae was found to survive equally well with two Myrmica ant species. We examine, however, the possibility that this reflects the presence of two separate Microdon species, each connected to one species of Myrmica. 3. Forty populations of Microdon myrmicae and 37 populations of Microdon mutabilis are currently known in Europe. All the populations in central and southern Europe that were visited after the separation of the two species were identified as Microdon myrmicae, while Microdon ...
Overall, this study provides information on bacterial communities associated with different life stages of Lucilia and their horizontal and trans-generational transmission, which may help in the development of better vector-borne disease management and MDT methods. Lucilia Robineau-Desvoidy (Diptera: Calliphoridae) is a blow fly genus of forensic, medical, veterinary, and agricultural importance. This genus is also famous because of its beneficial uses in maggot debridement therapy (MDT). Although the genus is of considerable economic importance, our knowledge about microbes associated with these flies and how these bacteria are horizontally and trans-generationally transmitted is limited. Results from the current study suggest that the majority of bacteria associated with these flies belong to phyla Proteobacteria, Firmicutes, and Bacteroidetes, and most bacteria are maintained intragenerationally, with a considerable degree of turnover from generation to generation. In both species, ...
In a previous study, we have shown that a newly identified chromosomal protein, RMSA-1 (Regulator of Mitotic Spindle Assembly-1), identified and cloned using a human autoimmune, serum, is essential for mitotic spindle assembly; we proposed that RMSA-1 was a previously unknown physiological substrate for cdc 2 kinase. In the present study, we show that this protein is present in crane fly and is associated with the chromosomes of spermatocytes. A 31 kDa molecule in extracts from crane-fly nuclei, isolated from larvae, pupae and adults, reacts with affinity-purified anti-RMSA-1 autoantibody, shown by immunoblotting. The autoantibody reacts, as shown by immunofluorescence, with crane-fly spermatocyte chromosomes in prophase through anaphase of both meiosis-1 and meiosis-II but does not react with preprophase or telophase nuclei or with spermatid nuclei. In all meiotic stages, the crane-fly sex chromosomes stain more intensely than the autosomes. We conclude that, since RMSA-1 is present in insect ...
The government of Saskatchewan is recommending people avoid all unnecessary travel to and from Regina. The direction comes as coronavirus variant transmission continues to increase in the Queen City. As of March 22, there were 156 confirmed variants of concern cases in the province, with 90 per cent - 141 cases - in Regina. There are also 748 presumptive variants of concern cases in Saskatchewan and 640 of those are in Regina. The province said people in Regina should not increase their household bubbles and should stay with their current household. Worship services around Saskatchewan have expanded, however they are not permitted to do that in Regina until April 5. The province said the request to avoid unnecessary travel is one of the ways to minimize the risk in the city and throughout the region. Other ways are for people to reduce activities outside of their home, order take-out or curbside pick-up and work from home if possible.
Olivier Lepage of the University of Lyon, who led the study, concluded: These results show that maggot debridement therapy potentially has an integral place in modern veterinary wound care. It can be used to treat many types of lesions, although not those involving tumours or bone sequestration. Associated high costs present a limiting factor but maggot debridement therapy should certainly be considered for lesions that fail to respond to conventional methods.. Professor Celia Marr, Editor of the EVJ, said Horses often suffer from non-healing wounds, particularly in the limbs where the skin is under continuous movement and there is very little subcutaneous tissue. Although at first glance this study might seem counter-intuitive and we might think of maggots as being the last thing one would want on a clean wound, it shows that maggots can be an effective way to clear damaged tissue and this is an important adjunctive approach in equine wound management.. 1The use of maggot debridement ...
of the medfly Ceratitis capitata. Cctra is regulated, as in Our results show that Ceratitis and Drosophila sex- Drosophila, by sex-specific splicing and encodes a protein determining cascades share a conserved tra,dsx genetic showing, as expected, low sequence conservation, when module to control sex determination and sexual differentiation compared with TRA proteins of Drosophila species (ONeil, as well as that tra sex-specific splicing regulation differs in the and Belote, 1992). We present evidence that female two species. In Drosophila, TRA protein, together with TRA- development depends on an active Cctra that, in XX 2, binds to the TRA/TRA-2 recognition sequences on the individuals, seems to promote the productive mode of Drosophila dsx pre-mRNA and promotes the use of a nearby transformer in Ceratitis 3723 female-specific acceptor site. We show that Cctra is needed to As zygotes that carry a Y chromosome do not activate Cctra impose the female-specific splicing of Ccdsx, most probably ...
Adult house flies, Musca domestica L., are mechanical vectors of more than 100 devastating diseases that have severe consequences for human and animal health. House fly larvae play a vital role as decomposers of animal wastes, and thus live in intimate association with many animal pathogens. We have sequenced and analyzed the genome of the house fly using DNA from female flies. The sequenced genome is 691 Mb. Compared with Drosophila melanogaster, the genome contains a rich resource of shared and novel protein coding genes, a significantly higher amount of repetitive elements, and substantial increases in copy number and diversity of both the recognition and effector components of the immune system, consistent with life in a pathogen-rich environment. There are 146 P450 genes, plus 11 pseudogenes, in M. domestica, representing a significant increase relative to D. melanogaster and suggesting the presence of enhanced detoxification in house flies. Relative to D. melanogaster, M. domestica has also
We have not had any luck finding similar looking images online, but we believe this is a female Horse Fly in the family Tabanidae. Interestingly, our searches did bring up images of a gold butt Horse Fly that was captured in 1981 in Australia and has recently been named after pop diva Beyonce. According to Asian Scientist: A previously un-named species of horse fly with golden hair on its lower abdomen has been named in honor of pop diva, Beyoncé - a member of the former group Destinys Child. AsianScientist (Jan. 13, 2012) - A previously un-named species of horse fly with golden hair on its lower abdomen has been named in honor of pop diva, Beyoncé - a member of the former group Destinys Child, that recorded the 2001 hit single, Bootylicious.

An Israeli start-up has introduced an intriguing potential solution to world hunger - fruit fly larvae. The company, Flying SpArk, co-founded by Eran Gronich and Yoram Yerushalmi in 2014, uses fruit fly larvae to make a protein powder (in regular and low-fat varieties) and oil, both of which are odorless and flavorless. These products can then be used to make everything from substitute meat patties to pasta, cereal, and even bread.. Fruit flies have a lifespan of only six days but multiply up to 15 times in that time, making them easy and cheap to farm and harvest. There is virtually no waste created in the process, as all parts of the larvae are used. This gives them an edge over conventional protein sources like poultry or cattle, but also over insects like grasshoppers or crickets, because they have no legs, wings, antennas or eyes. And while, Flying SpArk doesnt believe its fruit fly powder can completely replace meat, the company hopes that by becoming a part of human diet, it can at least ...

The human bot fly (Dermatobia hominis) belongs to the insect order Diptera, family Cuterebridae. The adult is a stout-bodied, hairy fly native to Central and South America. In fact, the above larval hitchhiker was picked up in Costa Rica. The egg-laden adult female fly temporarily captures a mosquito and attaches her eggs to its body. This encounter presumably occurs during the hours of dusk or later. When the mosquito lands on the warm body of a human for its blood meal, the bot fly eggs hatch and one or more pear-shaped larvae (maggots) fall to the skin surface. The larva bores into the skin and leaves a small breathing pore.. ...
Common green bottle fly is common all over the temperate and tropical regions of the planet. It prefers warm and moist climates and accordingly is especially common in coastal regions, but it also is present in arid areas. The female lays her eggs in meat, fish, animal corpses, infected wounds of humans or animals, and excrement. The larvae feed on decomposing tissue. The insect favours domestic sheep. This can lead to blow fly strike, causing problems for sheep farmers.. The life cycle of Lucilia is typical of flies in the family Calliphoridae in that the egg hatches into a larva that passes through three instars, enters a prepupal and then a pupal stage before emerging into the adult stage or imago. The female lays a mass of eggs in a wound, a carcass or corpse, or in necrotic or decaying tissue. The eggs hatch in about 9 hours in warm, moist weather, but may take as long as three days in cooler weather. In this, they differ from the more opportunistic Sarcophagidae, that lay hatching eggs or ...
