Insects-pest is animal populations, which occurred in every possible environment with a varied number of species. The several insects are vectors of different diseases, and cause damages to crop plants. These have been affecting economy and the yield of crop plant and at national and international market. The crop yield losses caused by insects in agriculture, several chemicals have been applie...

Helicoverpa armigera nucleopolyhedrovirus (HearNPV) has proved effective as the basis for various biological insecticides. Complete genome sequences of five Spanish HearNPV genotypes differed principally in the homologous regions (hrs) and the baculovirus repeat open reading frame (bro) genes, suggesting that they may be involved in the phenotypic differences observed among genotypes.

The mitochondrial genome (mitogenome) of the bollworm, Helicoverpa zea (Boddie), was assembled using paired-end nucleotide sequence reads generated with a next-generation sequencing platform. Assembly resulted in a mitogenome of 15,348 bp with greater than 17,000-fold average coverage. Organization of the H. zea mitogenome (gene order and orientation) was identical to other known lepidopteran m...

A recombinant Helicoverpa armigera nucleopolyhedrovirus (HearNPV), Ar1b-HearNPV, was constructed and identified as an improved bio-control agent of Helicoverpa armigera larvae. The HearNPV polyhedrin promoter was used to express the insect-specific neurotoxin gene, ar1b, which was originally isolated from the Australian funnel-web spider (Atrax robustus). RT-PCR and Western blotting analysis sh...

Paenibacillus sp. strain ICGEB2008 (MTCC 5639) is a Gram-positive cellulolytic bacterium, isolated from the gut of Helicoverpa armigera. Here, we report the draft genome sequence of Paenibacillus sp. ICGEB2008. The annotation of the ~5.7-Mb sequence indicated a cluster of genes related to the glycosyl hydrolase family and the butanediol biosynthesis pathway.

Male moths efficiently recognize conspecific sex pheromones thanks to their highly accurate and specific olfactory system. The Heliothis/Helicoverpa species are regarded as good models for studying the perception of sex pheromones. In this study, we performed a series of experiments to investigate the peripheral mechanisms of pheromone coding in two-closely related species, Helicoverpa armigera...

Helicoverpa are important polyphagous agricultural insect pests and they have a worldwide distribution. In this study, we report the bacterial community structure in the midgut of fifth instar larvae of Helicoverpa armigera, a species prevalent in the India, China, South Asia, South East Asia, Southern & Eastern Africa and Australia. Using culturable techniques, we isolated and identified membe...

Quercetin as one of the key plant secondary metabolite flavonol is ubiquitous in terrestrial plants. In this study, the decrease in sensitivity to lambda-cyhalothrin was observed in quercetin-fed Helicoverpa armigera larvae. In order to figure out the mechanisms underlying the decreased sensitivity of H. armigera larvae to lambda-cyhalothrin by quercetin induction, the changes in carboxylestera...

multivariate analyses of the morphological variation in five geographical populations of the pod borer, helicoverpa armigera (hã¼bner), was performed using 15 and 12 landmarks selected from the fore- and hindwings respectively. using their geometric morphometric characters (26 in the forewings and 20 in the hindwings), 287 and 277 images of fore- and hindwings were made respectively. analyses o...

the cotton bollworm, helicoverpa armigera (hübner), is a serious pest on a wide range of economic crops in many parts of the world. in this study, digestive proteolytic and amylolytic activities of h. armigera larvae (3rd to 5th instars) were evaluated on five main host plants including chickpea (cv hashem), cowpea (cv mashhad), soybean (cv 033), navybean (cv dehghan), and corn (cv sc 704) at 2...
