Insecticide resistance in Bemisia tabaci - Current status and implications for management

Resistance in Bemisia tabaci to organophosphates (Ops), carbamates, pyrethroids and endosulfan is widespread and the use of previously synergistic OP/pyrethroid mixtures appears to be selecting for new or modified resistance mechanisms. Resistance to the newest and most promising whitefly insecticides such as buprofezin, pyriproxyfen and imidacloprid has already been detected in localised areas. Considering the extent to which whiteflies are transported between countries the implications for countries and cropping-systems that receive these invaders are critical.
