Assessing the Risk of Bt Plants vs Conventional ...

The goal of this project is to make a comparative assessment of the effects of Bt plants and conventional insecticides on the persistence and population dynamics of a parasitoid and predator and, in turn, their effects on pest suppression and evolution of insecticide resistance in the pest population. To accomplish this we will use our unique tritrophic system of insects that carry resistance ...

Bacillus thuringiensis (Bt) for Pest Control | Planet Natural

Bacillus thuringiensis (Bt) is a natural occurring, soil-borne bacteria that has been used since the 1950s for natural insect control.It consists of a spore, which gives it persistence, and a protein crystal within the spore, which is toxic. That toxic protein differs, depending on the subspecies of Bt producing it, yielding a variance of Bt toxic to different insect species (or none at all).
