Dr. David Onstad from DuPont Pioneer will be presenting a seminar as part of the Department of Entomology's spring semester seminar series.
Abstract. Empirical and modeling studies have shown that the positive and negative influences of natural enemies on the durability of insecticidal traits are determined by the timing of attack, the reaction to pest density, and the specificity of attacks on pest phenotypes. This brief survey will highlight some of these lessons. The effects of insecticidal traits on natural enemies and the complexities of negative cross-resistance will not be addressed. The potential for positive integration for IPM will be identified.
