We have completed our annual survey for the insecticidal response of field populations of the Asian citrus psyllid (ACP) to a panel of insecticides with various modes of action. In years 2009 through 2012, we began to see a drop in susceptibility to all major insecticide classes in a number of ACP populations across central and southern Florida. In the surveys conducted in 2013 and 2014, we found a reversal in the LD50 response of all field populations to levels that were not significantly different from the reference laboratory strain. However, most population dose-response curves were significantly different from the laboratory strain and between one another in both years, suggesting that there is divergence in insecticide response between populations that may have a genetic basis. These results indicate that certain populations of ACP may be primed for resistance development if insecticide use does not continue to be managed strategically and conservatively. We will continue to monitor the insecticidal response in ACP closely. This year we added two additional sites in the survey for select insecticides, and plan to add additional ones next year as well to further our understanding of the natural and induced response of ACP to insecticidal exposure. Overall, it appears that rotations have been effective in decreasing the incidence of insecticide resistance in populations of ACP.
