During investigations; homology model of 3D-structure was built for sequence of polyhedrin protein of Helicoverpa armigera nucleopolyhedrovirus, containing 246 amino acids (Accession: ACI05106.1 GI: 205946055), and evaluated through multiple tools/ applications to judge extent of accuracy in light of existing crystal structure.

Resistance Mechanisms of Helicoverpa armigera
2016The cotton bollworm, Helicoverpa armigera, is one of the major agricultural pest species in the Old World and recently also of the New World. This noctuid moth species is highly polyphagous and possesses a huge geographical distribution and the ability to quickly evolve resistance to insecticides from different chemical classes.

2.4. Effect of GHQ (9) on growth and development of H. zea larvae Since gossypol (1) and related terpenoids are important components in the plant’s arsenal of terpenoids that protect it from herbivorous insects, it seemed appropriate to test the toxicity of GHQ (9) to insects.

Genetically engineered crops expressing insecticidal toxins from Bacillus thuringiensis (Bt) have improved the management of targeted lepidopteran pests and reduced the use of insecticide sprays. These benefits explain an increasing adoption of Bt crops worldwide, intensifying the selection pressure on target species and the risk of resistance ...

BACKGROUND The cotton bollworm Helicoverpa armigera is a worldwide insect pest with the ability to develop resistance to many insecticides. Indoxacarb, a sodium channel blocker, is an important insecticide that is used to control H. armigera.

Patterns of endothermic warm-up and flight thresholds were determined for Helicoverpa punctigera and H. armigera. Both species utilise endothermic mechanisms of heat gain to raise thoracic temperature (T(th)) to a level at which flight is possible. Endothermic warm-up, accomplished by wing shivering, was possible from a minimum of 3-5-degrees-C.

The two closely related moth species, Helicoverpa armigera and H. assulta, are sympatric in China. Both species use a mixture of (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-9-hexadecenal (Z9-16:Ald) as their sex pheromones but in widely different ratios. Hybridization and backcrossing experiments between H. armigera and H.
