Plain Language Summary
This two-page note gives an overview of the research into the development of Bacillus thuringiensis (Bt) by the Canadian Forest Service. This CFS success story highlights the early work on Bt, including how it works and how to measure potency and current research into improving the timing and application of treatments for insect pests such as the spruce budworm, gypsy moth and eastern tent caterpillar. Several models have been constructed that will help optimize spray applications. A database of Bt toxin specificity enables researchers to share information and improve the toxicity of the pathogen. This biological pesticide is an important part of integrated pest management in Canada and throughout the world and supports the government’s mandate to protect Canada’s natural resources from disturbances.
