Journal ArticleDOI

Songdou Zhang,Shiheng An,Zhen Li,Fengming Wu,Qingpo Yang,Yichen Liu,Jinjun Cao,Huaijiang Zhang,Qingwen Zhang,Xiaoxia Liu +9 more
TL;DR: This study establishes an accurate method for normalizing qRT-PCR data and serves as a reference for further study on gene transcription in H. armigera and other insects.
Journal ArticleDOI
Assessment of cotton aphids, Aphis gossypii, and their natural enemies on aphid‐resistant and aphid‐susceptible wheat varieties in a wheat–cotton relay intercropping system
TL;DR: In this article, the role of four winter wheat varieties that were resistant or susceptible to wheat aphid, Sitobion avenae Fabricius (Homoptera: Aphididae), in conserving arthropod natural enemies and suppressing cotton aphids in a wheat-cotton relay intercropping system in northern China was evaluated.
Journal ArticleDOI
Effects of Bacillus thuringiensis toxin Cry1Ac and Beauveria bassiana on Asiatic corn borer (Lepidoptera: Crambidae)
TL;DR: Not only were larval growth and development delayed, but pupation, pupal weight and adult emergency also decreased when larvae were fed on artificial diet containing purified Cry1Ac toxin.
Journal ArticleDOI
Effects of the Cry1Ac toxin of Bacillus thuringiensis on Microplitis mediator, a parasitoid of the cotton bollworm, Helicoverpa armigera
TL;DR: The growth of H. armigera larvae was delayed and its pupal rate and pupal weight decreased when they were fed on a diet containing Cry1Ac toxin, and the longevity of female and male parasitoids was not significantly affected when newly emerging wasps fed on honey solutions containing three different concentrations of Cry1ac toxin.
Journal ArticleDOI
Host age preference of Microplitis mediator (Hymenoptera: Braconidae), an endoparasitoid of Mythimna separata (Lepidoptera: Noctuidae)
TL;DR: The results of this study suggest that 2nd and 3rd instars of M. separata would be the best host stages for mass production of Microplitis mediator in the laboratory and thebest host instars to target for effective control in field releases.
