Abstract
The evolution of resistance to crops engineered with Bacillus thuringiensis toxins, and the effects of natural enemies thereon, has not been widely experimentally investigated. Selection experiments using Plutella xylostella will measure the effects of single and multiple toxins on the evolution of (1) Bt resistance and (2) correlated responses in resistance to natural enemies and novel Bt toxins. The effects of interactions between a pathogen (a granulosis virus) and Bt toxins on relative fitness of resistant and susceptible insects will be investigated, and also the effect of Bt-pathogen interactions on the rate of evolution of resistance in density controlled microcosms, and in microcosms with density dependent virus mortality.
