• The apple clearwing moth, Synanthedon myopaeformis (Borkhausen), (Lepidoptera: Sesiidae) is a serious pest of apple trees in British Columbia (BC) in Canada. Due to its recent introduction to BC and the lack of natural predators, the development of an attract and kill formulation using SPLAT® to control this pest in BC was initiated. SPLAT droplet shape and pheromone dose affected male moth attraction to traps; SPLAT droplets molded into hemispheres baited with 1- or 10 mg of sex pheromone were the most attractive. The addition of codlemone, the sex pheromone of a sympatric species, the codling moth (Cydia pomonella, L.) (Lepidoptera: Tortricidae), and the pyrethroid insecticide, cypermethrin, did not affect attraction of male apple clearwing moths to sex pheromone released from SPLAT. The use of visual cues characteristic of female apple clearwing moths enhanced male moth close-range orientation to pheromone-baited SPLAT and increased the number of contacts made to droplets.
