molecular analysis of divergence in tachinid uzi (exorista sorbillans) populations in india.exorista sorbillans is a tachinid endoparasitoid of silkworm, bombyx mori, and is globally known as uzi. it causes economic injury to the cocoon crop in silkworm cultivating areas of india, except those above 400 m above mean sea level (amsl) in the foothills of the himalayas (darjeeling). it is reported that the sericulture tract of south india became infected with this pest only since 1980 through an accidental transportation of cocoons from west bengal. to ascertain whether the genome of this ...200516175450
wolbachia and reproductive conflict in exorista sorbillans.many arthropods harbour endosymbiotic bacteria of the genus wolbachia. these endosymbionts are transmitted vertically from one generation to the next and are obligatory in several dipterans that have been studied to date. these bacteria induce an array of reproductive isolation mechanisms that are implicated in pest management to evolutionary biology of respective hosts. the uzifly, exorista sorbillans, a tachinid endoparasitoid of the silkworm, bombyx mori l. (lepidoptera: bombycidae), causes e ...200516304620
effects of wolbachia in the uzifly, exorista sorbillans, a parasitoid of the silkworm, bombyx mori.the uzifly, exorista sorbillans (diptera: tachinidae), a parasitoid of the silkworm, bombyx mori l. (lepidoptera: bombycidae), harbours wolbachia (rickettsia) endosymbionts. administration of 0.05 mg/ml oxytetracycline to the adult uziflies removed wolbachia endosymbionts and resulted in different reproductive disorders, such as i) reduction in fecundity of uninfected females, ii) cytoplasmic incompatibility in crosses between infected males and uninfected females, iii) sterility in the crosses ...200517119612
survey of wolbachia and its phage wo in the uzifly exorista sorbillans (diptera: tachinidae).wolbachia are cytoplasmically inherited alpha-proteobacteria well known for inducing a variety of reproductive abnormalities in the diverse arthropod hosts they infect. despite their obligate intracellular lifestyle which usually protects bacteria from phage infection, wolbachia harbor a widespread temperate phage called wo. evidences of horizontal phage transfers indicate that this phage could promote genetic exchanges between strains leading to evolutionary changes in the genomes of wolbachia, ...201121739251
molecular characterization and inhibition analysis of the acetylcholinesterase gene from the silkworm maggot, exorista sorbillans.several organophosphorus (op) insecticides can selectively kill the silkworm maggot, exorista sorbillans (es) (diptera: tachinidae), while not obviously affecting the host (bombyx mori) larvae, but the mechanism is not yet clear. in this study, the cdna encoding an acetylcholinesterase (ache) from the field es was isolated. one point mutation (gly353ala) was identified. the es-353g ache and es-353a ache were expressed in baculovirus- insect cell system, respectively. the inhibition results showe ...201020797321
parasitoids of gangara thyrsis (fabricius) (lepidoptera: hesperiidae) with description of a new species of agiommatus crawford, 1911 (hymenoptera: pteromalidae) from india with notes on biology.in rearing of gangara thyrsis (fabricius) (lepidoptera: hesperiidae) from karnataka and goa, india, six species of parasitoids were observed. one new species of parasitic wasp is described and illustrated: agiommatus thyrsisae n. sp. (hymenoptera: pteromalidae), a solitary parasitoid reared from the egg of g. thyrsis on the natural host plant dypsis lutescens (h. wendl.) beentje & j. dransf. three additional species of parasitic wasps were also reared: anastatus ramakrishnai (mani, 1935) (hymeno ...201627307173
structure and evolution of the mitochondrial genome of exorista sorbillans: the tachinidae (diptera: calyptratae) perspective.the first complete mitochondrial genome (mitogenome) of tachinidae exorista sorbillans (diptera) is sequenced by pcr-based approach. the circular mitogenome is 14,960 bp long and has the representative mitochondrial gene (mt gene) organization and order of diptera. all protein-coding sequences are initiated with atn codon; however, the only exception is cox i gene, which has a 4-bp atcg putative start codon. ten of the thirteen protein-coding genes have a complete termination codon (taa), but th ...201223053992
