Cranberry Tipworm (CTW), Dasineura oxycoccana Johnson), is a key pest of rabbiteye blueberries (Vaccinium ashei Reade) in southeastern United States. Larvae feed on young meristematic tissues and developing buds. In an attempt to develop an integrated approach for control of CTW, I studies four commonly used rabbiteye varieties for susceptibility, and screened reduced-risk and conventional insecticides. Premier appears to be a more susceptible variety, and several reduced-risk insecticides show potential for controlling CTW.
