A female-specific odorant receptor mediates oviposition deterrence in the moth Helicoverpa armigera.

Current Biology, 2023
Finding ideal oviposition sites is a task of vital importance for all female insects. To ensure optimal conditions for their progeny, females of herbivorous insects detect not only the odors of a relevant host plant but also chemicals released by eggs ...

Transcription factor CncC potentially regulates cytochrome P450 CYP321A1-mediated flavone tolerance in Helicoverpa armigera.

Pesticide Biochemistry and Physiology, 2023
Insect P450s play crucial roles in metabolizing insecticides and toxic plant allelochemicals. In this study, our results demonstrate that Helicoverpa armigera can adapt to a lower concentration of flavone (a flavonoid phytochemical), and P450 activities ...

Chitosan nanocarriers mediated dsRNA delivery in gene silencing for Helicoverpa armigera biocontrol.

Pesticide Biochemistry and Physiology, 2022
Specific gene silencing by RNA interference (RNAi) involving exogenous double stranded RNA (dsRNA) delivery has potential in Helicoverpa armigera control, a resistant insect pest. Here, ionotropically synthesized cationic chitosan nanoparticles (CNPs, 95

MicroRNAs miR-14 and miR-2766 regulate tyrosine hydroxylase to control larval-pupal metamorphosis in Helicoverpa armigera.

Pest Management Science, 2022
BACKGROUND The cotton bollworm, Helicoverpa armigera, is a worldwide polyphagous pest, causing huge economic losses in vegetable, cotton, corn, etc. Due to the long-term exposure to Bacillus thuringiensis (Bt) toxins, evolution of resistance by this pest

Field-evolved resistance to eleven insecticides and the mechanisms involved in Helicoverpa armigera (Lepidoptera: Noctuidae).

Pest Management Science, 2021
BACKGROUND To understand the ongoing resistance of cotton bollworm, Helicoverpa armigera, the sensitivity of five field populations to commonly used insecticides, i.e. indoxacarb, abamectin, methoxyfenozide, chlorfenapyr, chlorantraniliprole, spinetoram,

Pyrethroid metabolism by eleven Helicoverpa armigera P450s from the CYP6B and CYP9A subfamilies.

Insect Biochemistry and Molecular Biology, 2021
Lepidopteran P450s of the CYP6B and CYP9A subfamilies are thought to play important roles in host plant adaptation and insecticide resistance. An increasing number of paralogs and orthologs with high levels of sequence identity have been found in these ...
