Genetic Basis for Variability of Cry1Ac Expression Among Commercial Transgenic Bacillus thuringiensis (Bt) Cotton Cultivars in the United States

Study shows that genetic background has a major effect on Cry1Ac expression in Bt cotton cultivars. It also provides a summary of studies pointing to limitations in Bt cotton's control of many lepidopteran pest.

Influence of Pesticide Applications on Pest and Predatory Arthropods Associated with Transgenic Bt Cotton and Nontransgenic Cotton Plants

"The use of Bt cotton did not lead to a reduction in total numbers of insecticide sprays in the course of 3 years because additional sprays were required against sucking pests."
