Plum curculio (Conotrachelus nenuphar Herbst) is a primary pest of tree fruit east of the Rocky Mountains. Traditionally, plum curculio has been controlled using organophophates, but increased government regulation of pesticides has forced reevaluation of these control strategies. Additionally, the increased popularity of organic tree fruit production has necessitated the need for novel control strategies, as organic tree fruit growers name plum curculio as their biggest insect threat. A number of behavior related strategies have been developed for this pest, including traps baited with plant volatile lures and the use of kaolin clay. Pyganic is an organc insecticide that is currently the best chemical organic growers have to control plum curculio. A strategy that integrated the tools that organic growers already have available has been field tested in apple and cherry. This strategy involves attracting plum curculio to the outer rows nof the orchard and utilizing pyramid traps to monitor their population. When plum curculio catches were sufficient, the outside rows were sprayed with Pyganic. Success of this strategy was measured with comprehensive damage sampling. This strategy may prove to be a viable option for both conventional and organic growers.
