The class Insecta, in the phylum ARTHROPODA, whose members are characterized by division into three parts: head, thorax, and abdomen. They are the dominant group of animals on earth; several hundred thousand different kinds having been described. Three orders, HEMIPTERA; DIPTERA; and SIPHONAPTERA; are of medical interest in that they cause disease in humans and animals. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p1)
Family of INSECT VIRUSES containing two subfamilies: Eubaculovirinae (occluded baculoviruses) and Nudibaculovirinae (nonoccluded baculoviruses). The Eubaculovirinae, which contain polyhedron-shaped inclusion bodies, have two genera: NUCLEOPOLYHEDROVIRUS and GRANULOVIRUS. Baculovirus vectors are used for expression of foreign genes in insects.
An order of the class Insecta. Wings, when present, number two and distinguish Diptera from other so-called flies, while the halteres, or reduced hindwings, separate Diptera from other insects with one pair of wings. The order includes the families Calliphoridae, Oestridae, Phoridae, SARCOPHAGIDAE, Scatophagidae, Sciaridae, SIMULIIDAE, Tabanidae, Therevidae, Trypetidae, CERATOPOGONIDAE; CHIRONOMIDAE; CULICIDAE; DROSOPHILIDAE; GLOSSINIDAE; MUSCIDAE; TEPHRITIDAE; and PSYCHODIDAE. The larval form of Diptera species are called maggots (see LARVA).

Pest Control, Biological
A genus of silkworm MOTHS in the family Bombycidae of the order LEPIDOPTERA. The family contains a single species, Bombyx mori from the Greek for silkworm + mulberry tree (on which it feeds). A native of Asia, it is sometimes reared in this country. It has long been raised for its SILK and after centuries of domestication it probably does not exist in nature. It is used extensively in experimental GENETICS. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p519)
Amino Acid Sequence
Insects of the family Formicidae, very common and widespread, probably the most successful of all the insect groups. All ants are social insects, and most colonies contain three castes, queens, males, and workers. Their habits are often very elaborate and a great many studies have been made of ant behavior. Ants produce a number of secretions that function in offense, defense, and communication. (From Borror, et al., An Introduction to the Study of Insects, 4th ed, p676)
A genus of gram-negative bacteria existing symbiotically with nematodes of the family Heterorhabditidae (see RHABDITOIDEA). These nematodes infect a variety of soil-dwelling insects. Upon entering an insect host, the nematode releases Photorhabdus from its intestinal tract and the bacterium establishes a lethal septicemia in the insect.
Periodic casting off FEATHERS; HAIR; or cuticle. Molting is a process of sloughing or desquamation, especially the shedding of an outer covering and the development of a new one. This phenomenon permits growth in ARTHROPODS, skin renewal in AMPHIBIANS and REPTILES, and the shedding of winter coats in BIRDS and MAMMALS.
A genus of gram-negative, facultatively anaerobic rod-shaped cells which are motile by peritrichous flagella. Late in the growth cycle, spheroplasts or coccoid bodies occur, resulting from disintegration of the cell wall. The natural habitat is the intestinal lumen of certain nematodes. (From Bergey's Manual of Determinative Bacteriology, 9th ed)
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Sequence Homology, Amino Acid
The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
Sequence Analysis, DNA
Arthropods of the class ARACHNIDA, order Araneae. Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms. (From Barnes, Invertebrate Zoology, 5th ed, p508; Smith, Insects and Other Arthropods of Medical Importance, 1973, pp424-430)
Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.
Life Cycle Stages
DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
Bugs of the family CIMICIDAE, genus Cimex. They are flattened, oval, reddish insects which inhabit houses, wallpaper, furniture, and beds. C. lectularius, of temperate regions, is the common bedbug that attacks humans and is frequently a serious pest in houses, hotels, barracks, and other living quarters. Experiments have shown that bedbugs can transmit a variety of diseases, but they are not normal vectors under natural conditions. (From Dorland, 27th ed; Borror, et al., An Introduction to the Study of Insects, 4th ed, p272)
A gene silencing phenomenon whereby specific dsRNAs (RNA, DOUBLE-STRANDED) trigger the degradation of homologous mRNA (RNA, MESSENGER). The specific dsRNAs are processed into SMALL INTERFERING RNA (siRNA) which serves as a guide for cleavage of the homologous mRNA in the RNA-INDUCED SILENCING COMPLEX. DNA METHYLATION may also be triggered during this process.
Volatile Organic Compounds
Apontic binds the translational repressor Bruno and is implicated in regulation of oskar mRNA translation. (1/4849)The product of the oskar gene directs posterior patterning in the Drosophila oocyte, where it must be deployed specifically at the posterior pole. Proper expression relies on the coordinated localization and translational control of the oskar mRNA. Translational repression prior to localization of the transcript is mediated, in part, by the Bruno protein, which binds to discrete sites in the 3' untranslated region of the oskar mRNA. To begin to understand how Bruno acts in translational repression, we performed a yeast two-hybrid screen to identify Bruno-interacting proteins. One interactor, described here, is the product of the apontic gene. Coimmunoprecipitation experiments lend biochemical support to the idea that Bruno and Apontic proteins physically interact in Drosophila. Genetic experiments using mutants defective in apontic and bruno reveal a functional interaction between these genes. Given this interaction, Apontic is likely to act together with Bruno in translational repression of oskar mRNA. Interestingly, Apontic, like Bruno, is an RNA-binding protein and specifically binds certain regions of the oskar mRNA 3' untranslated region. (+info)
The Drosophila kismet gene is related to chromatin-remodeling factors and is required for both segmentation and segment identity. (2/4849)The Drosophila kismet gene was identified in a screen for dominant suppressors of Polycomb, a repressor of homeotic genes. Here we show that kismet mutations suppress the Polycomb mutant phenotype by blocking the ectopic transcription of homeotic genes. Loss of zygotic kismet function causes homeotic transformations similar to those associated with loss-of-function mutations in the homeotic genes Sex combs reduced and Abdominal-B. kismet is also required for proper larval body segmentation. Loss of maternal kismet function causes segmentation defects similar to those caused by mutations in the pair-rule gene even-skipped. The kismet gene encodes several large nuclear proteins that are ubiquitously expressed along the anterior-posterior axis. The Kismet proteins contain a domain conserved in the trithorax group protein Brahma and related chromatin-remodeling factors, providing further evidence that alterations in chromatin structure are required to maintain the spatially restricted patterns of homeotic gene transcription. (+info)
Insect evolution: Redesigning the fruitfly. (3/4849)Homeotic mutations in Drosophila can result in dramatic phenotypes that suggest the possibility for rapid morphological evolution, but dissection of the genetic pathway downstream of Ultrabithorax is beginning to reveal how wing morphology may have evolved by more gradual transformations. (+info)
Why are there so few resistance-associated mutations in insecticide target genes? (4/4849)The genes encoding the three major targets of conventional insecticides are: Rdl, which encodes a gamma-aminobutyric acid receptor subunit (RDL); para, which encodes a voltage-gated sodium channel (PARA); and Ace, which encodes insect acetylcholinesterase (AChE). Interestingly, despite the complexity of the encoded receptors or enzymes, very few amino acid residues are replaced in different resistant insects: one within RDL, two within PARA and three or more within AChE. Here we examine the possible reasons underlying this extreme conservation by looking at the aspects of receptor and/or enzyme function that may constrain replacements to such a limited number of residues. (+info)
The role of gene splicing, gene amplification and regulation in mosquito insecticide resistance. (5/4849)The primary routes of insecticide resistance in all insects are alterations in the insecticide target sites or changes in the rate at which the insecticide is detoxified. Three enzyme systems, glutathione S-transferases, esterases and monooxygenases, are involved in the detoxification of the four major insecticide classes. These enzymes act by rapidly metabolizing the insecticide to non-toxic products, or by rapidly binding and very slowly turning over the insecticide (sequestration). In Culex mosquitoes, the most common organophosphate insecticide resistance mechanism is caused by co-amplification of two esterases. The amplified esterases are differentially regulated, with three times more Est beta 2(1) being produced than Est alpha 2(1). Cis-acting regulatory sequences associated with these esterases are under investigation. All the amplified esterases in different Culex species act through sequestration. The rates at which they bind with insecticides are more rapid than those for their non-amplified counterparts in the insecticide-susceptible insects. In contrast, esterase-based organophosphate resistance in Anopheles is invariably based on changes in substrate specificities and increased turnover rates of a small subset of insecticides. The up-regulation of both glutathione S-transferases and monooxygenases in resistant mosquitoes is due to the effects of a single major gene in each case. The products of these major genes up-regulate a broad range of enzymes. The diversity of glutathione S-transferases produced by Anopheles mosquitoes is increased by the splicing of different 5' ends of genes, with a single 3' end, within one class of this enzyme family. The trans-acting regulatory factors responsible for the up-regulation of both the monooxygenase and glutathione S-transferases still need to be identified, but the recent development of molecular tools for positional cloning in Anopheles gambiae now makes this possible. (+info)
Cytochrome P450 monooxygenases and insecticide resistance in insects. (6/4849)Cytochrome P450 monooxygenases are involved in many cases of resistance of insects to insecticides. Resistance has long been associated with an increase in monooxygenase activities and with an increase in cytochrome P450 content. However, this increase does not always account for all of the resistance. In Drosophila melanogaster, we have shown that the overproduction of cytochrome P450 can be lost by the fly without a corresponding complete loss of resistance. These results prompted the sequencing of a cytochrome P450 candidate for resistance in resistant and susceptible flies. Several mutations leading to amino-acid substitutions have been detected in the P450 gene CYP6A2 of a resistant strain. The location of these mutations in a model of the 3D structure of the CYP6A2 protein suggested that some of them may be important for enzyme activity of this molecule. This has been verified by heterologous expression of wild-type and mutated cDNA in Escherichia coli. When other resistance mechanisms are considered, relatively few genetic mutations are involved in insecticide resistance, and this has led to an optimistic view of the management of resistance. Our observations compel us to survey in more detail the genetic diversity of cytochrome P450 genes and alleles involved in resistance. (+info)
An overview of the evolution of overproduced esterases in the mosquito Culex pipiens. (7/4849)Insecticide resistance genes have developed in a wide variety of insects in response to heavy chemical application. Few of these examples of adaptation in response to rapid environmental change have been studied both at the population level and at the gene level. One of these is the evolution of the overproduced esterases that are involved in resistance to organophosphate insecticides in the mosquito Culex pipiens. At the gene level, two genetic mechanisms are involved in esterase overproduction, namely gene amplification and gene regulation. At the population level, the co-occurrence of the same amplified allele in distinct geographic areas is best explained by the importance of passive transportation at the worldwide scale. The long-term monitoring of a population of mosquitoes in southern France has enabled a detailed study to be made of the evolution of resistance genes on a local scale, and has shown that a resistance gene with a lower cost has replaced a former resistance allele with a higher cost. (+info)
Predicting insecticide resistance: mutagenesis, selection and response. (8/4849)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)

A bag-of-words approach for Drosophila gene expression pattern annotation
Background: Drosophila gene expression pattern images document the spatiotemporal dynamics of gene expression during embryogenesis. A comparative analysis of these images could provide a fundamentally important way for studying the regulatory networks governing development. To facilitate pattern comparison and searching, groups of images in the Berkeley Drosophila Genome Project (BDGP) high-throughput study were annotated with a variable number of anatomical terms manually using a controlled vocabulary. Considering that the number of available images is rapidly increasing, it is imperative to design computational methods to automate this task. Results: We present a computational method to annotate gene expression pattern images automatically. The proposed method uses the bag-of-words scheme to utilize the existing information on pattern annotation and annotates images using a model that exploits correlations among terms. The proposed method can annotate images individually or in groups (e.g., ...

Very disappointed. Prior to ordering, I discussed my requirement with a female representative from your company, wherein I asked if you had medium-sized escargots. She said no, but insisted that the next size up, quote large were considered medium. I discussed this at length with her, as I am very familiar with escargots, and know that the larger they are, the less tender they become. She kept insisting, however, that the large were consistent with medium-size. I gave in and accepted, ordering two cans of large escargots. Upon delivery, I immediately noticed that they were labeled very large. I called to voice my dissatisfaction, but this time a gentleman said they didnt even carry large, but instead went from petit to very large. Quite the contradiction from the first representative who insisted you carried large. I caved in and said we would go ahead and try the very large. Well, as I suspected, they were indeed rubbery and not acceptable. Very disappointed. By the way, I dont know ...

A Screen for New Trithorax Group Genes Identified little imaginal discs, the Drosophila melanogaster Homologue of Human...
We propose that the six genes previously classified as Polycomb group genes in which loss-of-function or antimorphic mutations show intergenic noncomplementation with mutations in trithorax group genes and increase the penetrance caused by double heterozygosis of mutations in trithorax group genes belong in a distinct group (Table 6). We propose that this group be called the ETP (Enhancers of trithorax and Polycomb mutations) group. Loss-of-function mutations in this group of genes enhance the dominant phenotype caused by Polycomb mutations like mutations in Polycomb group genes but also enhance the phenotype caused by heterozygosity for double mutations in trithorax group genes such as ash1VF101 trxb11 and brm2 trxe2 like mutations in trithorax group genes. Jürgens (1985) estimated that there were ∼40 genes in the Polycomb group based on the enhancement of the Polycomb mutant phenotype by a sample of deficiencies. We suggest that this number may be an overestimate. Many of the genes in which ...

Functional interactions of neurogenic genes of Drosophila melanogaster. | Genetics
The neurogenic genes of Drosophila melanogaster are involved in the decision of ectodermal cells to take on a neural or an epidermal fate. We present evidence in support of the notion that six of the neurogenic genes are functionally related. We studied the phenotype of embryos lacking one of the neurogenic genes in the presence of an increased dosage of the wild-type allele of another neurogenic gene. Our analysis also included the Hairless locus, whose function is related to that of the neurogenic genes, as well as to many other genes. The effects observed were asymmetric in that triploidy for a given gene modified the phenotype of loss of the function of another gene, but triploidy of the latter gene did not modify the phenotype of loss of the function of the former gene. These asymmetries allowed us to establish a polarity of gene interactions, as well as to order the genes according to the assumed ability of some of them to modify the activity of others. In this sequence, almondex is the ...
Female remating in Drosophila ananassae: bidirectional selection for remating speed - Cogprints
In Drosophila ananassae, artificial selection was carried out for fast and slow remating speed for 10 generations. Response to selection resulted in rapid divergence in remating time in each of two replicates of both fast and slow lines. There were significant differences in mean remat-ing time in females among fast, slow, and control lines. Regression coefficients for both fast and slow lines are significantly different from zero. The realized heritability over 10 genera-tions of selection is from 0.26 to 0.33 for two replicates of fast line and from 0.23 to 0.27 for two replicates of slow line. These findings suggest that female remating time in D. ananassae is under polygenic control. Remating frequency of females showed a correlated response in both fast and slow lines. At generation 10, correlated response to selection was also investigated. Mating propensity of D. ananassae of fast and slow lines was observed in an Elens-Wattiaux mating chamber. Fifteen pairs per test showed that on the ...
Loyola eCommons - Undergraduate Research and Engagement Symposium: Genome Annotation of Contig1 in Drosophila ananassae
DNA packaging affects a genes availability for transcription. Typically, loosely-packed euchromatic regions are gene rich and exhibit higher levels of gene transcription, while densely-packed heterochromatic regions are gene poor and exhibit less gene transcription. The 4th chromosome, or F Element, of Drosophila is unique, as it contains ~80 genes and is heterochromatic in nature, yet these genes are actively transcribed. Thus, Drosophila species provide an ideal model system for exploring how genes are accessed in heterochromatic regions and how well these mechanisms are conserved over millions of years of evolution. Working alongside the Genomics Education Partnership (GEP), genes of the F Element and the control D Element are being annotated across Drosophila species to identify unique features of genes on the F Element. My work has focused on contig1 of Drosophila ananassae. We have annotated the coding spans (CDS) of contig1, which contains five genes located on the autosomal euchromatic 3L
The Fab-8 boundary defines the distal limit of the bithorax complex iab-7 domain and insulates iab-7 from initiation elements...
The Drosophila bithorax complex Abdominal-B (Abd-B) gene specifies parasegmental identity at the posterior end of the fly. The specific pattern of Abd-B expression in each parasegment (PS) determines its identity and, in PS10-13, Abd-B expression is controlled by four parasegment-specific cis-regulatory domains, iab-5 to iab-8, respectively. In order to properly determine parasegmental identity, these four cis-regulatory domains must function autonomously during both the initiation and maintenance phases of BX-C regulation. The studies reported here demonstrate that the (centromere) distal end of iab-7 domain is delimited by the Fab-8 boundary. Initiators that specify PS12 identity are located on the proximal iab-7 side of Fab-8, while initiators that specify PS13 identity are located on the distal side of Fab-8, in iab-8. We use transgene assays to demonstrate that Fab-8 has enhancer blocking activity and that it can insulate reporter constructs from the regulatory action of the iab-7 and iab-8 ...

CriticalDance Forum • View topic - Rafael Amargo - flamenco
The dancing illustrates the poems from the book of poetry Federico Garcia Lorca wrote on his prodigious trip to New York. The Spaniards are fiercely proud of, and knowledgeable about, their poet and the manuscript of Poeta has been embroiled for years in litigation as to its ownership. The manuscript was finally sold at Christies in London in the summer. The poems are pre-filmed readings by famous Spanish actresses. Amargo uses film to good effect. One of the most poignant scenes is the silhouette of the elegant actress Marisa Paredes (who has appeared in Almodovar films and so is also well-known outside of Spain) reading the poem Jewish Cemetery against a backdrop of masses of gravestones. Other poems are read against the striking skyline of Manhattan. The use of film is complementary and unobtrusive. Your eye moves comfortably from the dancers to the flamenco singers and guitarists (as with most flamenco, the music is part of the scenery and the musicians are located on stage) and the to ...

- We have investigated the expression of homologs of the Drosophila Pax group III genes paired, gooseberry and gooseberry-neuro in short germ flour beetles and grasshoppers. (biologists.org)
- During Drosophila embryogenesis, paired acts as one of several pair-rule genes that define the boundaries of future parasegments and segments, via the regulation of segment polarity genes such as gooseberry, which in turn regulates gooseberry-neuro, a gene expressed later in the developing nervous system. (biologists.org)
- Using a crossreactive antibody, we show that the embryonic expression of Pax group III genes in both the flour beetle Tribolium and the grasshopper Schistocerca is remarkably similar to the pattern in Drosophila . (biologists.org)
- This early expression of pairberry1 is reminiscent of Drosophila paired and represents the first evidence for pair-rule patterning in short germ grasshoppers or any hemimetabolous insect. (biologists.org)
- In phylogenetically derived long germ insects such as Drosophila, this genetic hierarchy functions to define and pattern all segments almost simultaneously within the blastoderm. (biologists.org)
- Thus, crucial questions arise as to which components of the Drosophila segmentation hierarchy are shared by different short germ insects and how they might function in the short germ context. (biologists.org)
- Segment polarity genes were originally defined by their loss-of-function phenotypes in Drosophila, which reveal patterning defects within each segment of the embryonic cuticle ( Nüsslein-Volhard and Wieschaus, 1980 ). (biologists.org)
- Consistent with their phenotypes, most of these genes are expressed in Drosophila just before and throughout the morphologically segmented germ band stage in a segmentally reiterated pattern. (biologists.org)
- Pair-rule genes were also originally defined by their loss-of-function phenotypes in Drosophila , in which regions of the embryonic cuticle are deleted with a two-segment periodicity ( Nüsslein-Volhard and Wieschaus, 1980 ). (biologists.org)
- In Drosophila , all three of these genes are expressed in stripes of a two-segment periodicity before the onset of gastrulation. (biologists.org)
