To assess the ecological effects of Bt-cotton cultivars (ZMSJ and ZMKCKC, expressing Cry1Ac/Cry2Ab and Cry1Ac/EPSPS, respectively), laboratory experiments were performed to evaluate the transmission of Cry1Ac protein in the food chain and the effects of Bt toxin on the ladybeetle predator Propylaea japonica through its herbivorous prey Aphis gossypii. Trace amounts of Cry1Ac protein (3.0ng/g fresh ...

- ... Use of plant secondary metabolic compounds is an important method for insect pest control. In this study, the survival, development, and reproduction of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) MEAM1 cryptic species were compared over two consecutive generations on three cotton cultivars of different gossypol levels. Both cotton cultivar and generation significantly affected the fitness ...
