Insecticide Resistance in Western Flower Thrips

Karen L. Robb; Julie P. Newman; Judy K. Virzi; Michael P. Parrella

Leaf dip bioassays were used to determine the breadth of tolerance of three pesticides for western flower thrips (WFT) populations collected from greenhouses with minimal (’sD’ strain) and intensive insecticide use (’sB’ strain), and from a susceptible colony where no pesticides were applied for 1 yr prior to the study (‘UC’ strain). Additionally, five doses of three pesticides were applied topically. In the bioassays insecticide treatments were more efficacious against the ‘UC’strain than the field-collected strains; topical applications showed increased resistance levels in the’ sB’ strain.
