Development of diagnostic tools for monitoing insecticide resistance in California populations of the Asian citrus psyllid, Diaphorina citri

Insecticides are a critical component of management programs for populations of Asian Citrus Psyllid (ACP) in California citrus.  The development of insecticide resistance could seriously curtail the effectiveness of current control strategies, and it is imperative that a monitoring program be established to detect resistance at an early stage.  Our goal is to develop toxicological and molecular diagnostic tools for the detection of resistance to the major chemical classes used for ACP control.   Our progress in achieving that goal is summarized in this presentation.
