Fitness of Bt-resistant cabbage loopers on Bt cotton plants. [PDF]
Plant Biotechnol J, 2017 SummaryDevelopment of resistance to the insecticidal toxins from Bacillus thuringiensis (Bt) in insects is the major threat to the continued success of transgenic Bt crops in agriculture. The fitness of Bt‐resistant insects on Bt and non‐Bt plants is a key parameter that determines the development of Bt resistance in insect populations.

Modeling the evolution of resistance in cotton bollworm to concurrently planted Bt cotton and Bt maize in China [PDF]
Ecological Modelling, 2021 Abstract BackgroundTransgenic maize expressing toxins derived from the bacterium Bacillus thuringiensis (Bt) may be commercially planted in northern China where Bt cotton has been planted for more than two decades. While Bt maize brings additional benefits for insect control, it complicates the resistance management of cotton bollworm (CBW ...
