Bio/Research
Development of botanical insecticides and antifeedants. Collaborating with university and industrial partners, we have investigated the development of botanical insecticides derived from the neem tree (Azadirachta indica), from medicinal plants and timber species of southeast Asia and Central America, and from tall oil, a byproduct of the pulp and paper industry. Studies have included isolation and identification of active principles, modes-of-action against pest insects, effects on natural enemies and fish, and efficacy under greenhouse and field conditions. We are currently collaborating on the development of essential oil-based pesticides for EcoSMART Technologies Inc. (USA).
Behavioral and physiological effects of plant defensive chemicals on insects. We have investigated the effects of mixtures of plant chemicals on insect feeding and on the development of resistance to botanical insecticides. Studies have characterized habituation to feeding deterrents in caterpillars, the metabolism of plant defensive chemicals by herbivorous insects, and the pharmacokinetics and fate of plant chemicals in insects.
