Suppression of Calcineurin Enhances the Toxicity of Cry1Ac to Helicoverpa armigera [PDF]

Frontiers in Microbiology, 2021
Insect resistance to Bacillus thuringiensis (Bt) insecticidal proteins has rapidly evolved with the expansion of the planting area of transgenic Bt crops. Pyramiding RNA interference (RNAi) and Bt in crops is urgently needed to counter the rapid increase

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

Frontiers 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 ...
