Plant Metabolites Drive Different Responses in Caterpillars of Two Closely Related Helicoverpa Species

open access: yesFrontiers in Physiology, 2021
The host acceptances of insects can be determined largely by detecting plant metabolites using insect taste. In the present study, we investigated the gustatory sensitivity and feeding behaviors of two closely related caterpillars, the generalist ...

Identification of a Conserved Prophenoloxidase Activation Pathway in Cotton Bollworm Helicoverpa armigera

open access: yesFrontiers in Immunology, 2020
Melanization is a prominent insect humoral response for encapsulation of and killing invading pathogens. It is mediated by a protease cascade composed of a modular serine protease (SP), and clip domain SPs (cSPs), which converts prophenoloxidase (PPO ...

Hybridization and introgression between Helicoverpa armigera and H. zea: an adaptational bridge

open access: yesBMC Evolutionary Biology, 2020
Background Invasion of organisms into new ecosystems is increasingly common, due to the global trade in commodities. One of the most complex post-invasion scenarios occurs when an invasive species is related to a native pest, and even more so when they ...
