The transcriptome reveals the potential mechanism of 20E terminating diapause in cotton bollworm, Helicoverpa armigera.

ABSTRACT:

Background

Diapause is a crucial adaptive strategy employed across numerous insect species, endowing them to survive in unfavorable environments. Helicoverpa armigera, one of the most destructive pests globally, undergoes diapause in the pupa stage, which is essential for its survival during the overwintering period and ultimately determines the following year's population density. 20E is a primary hormone that regulates the process of pupae diapause. However, a comprehensive analysis of the mechanisms by which 20E regulates the initiation and termination of diapause in H. armigera remains lacking.

Results

In the present study, exogenous 20E was initially administered to diapausing pupae, and the results demonstrated that 20E markedly enhanced the development and eclosion ra
