Suppression of Calcineurin Enhances the Toxicity of Cry1Ac to Helicoverpa armigera

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

Battle in the New World: Helicoverpa armigera versus Helicoverpa zea (Lepidoptera: Noctuidae).

PLoS ONE, 2016
The corn earworm Helicoverpa zea (Boddie) and the old world bollworm Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) are allopatric species and occur in important agricultural crops. In maize, both species tend to infest the ear.

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

BMC 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 ...

Transcriptomic analysis of salivary gland and proteomic analysis of oral secretion in Helicoverpa armigera under cotton plant leaves, gossypol, and tannin stresses.

Genomics, 2022
Gossypol and tannin are involved in important chemical defense processes in cotton plants. In this study, we used transcriptomics and proteomics to explore the changes in salivary gland functional genes and oral secretion (OS) proteins after feeding with
