Extract

The sex pheromone of the spruce seed moth, Cydia strobilella (L.) (Lepidoptera: Tortricidae), has not yet been identified, but several chemicals were found to be attractive to males (reviewed by Grant et al. 1989). E8-Dodecenyl acetate (E8-12:OAc) at 0.3-3.0 μg doses was the only effective attractant for males in field experiments in British Columbia, Ontario, and Newfoundland (Grant et al. 1989). Our objectives were to (i) confirm that female C. strobilella produce E8-12:OAc as a pheromone component, (ii) determine whether females produce additional pheromone components, and (iii) investigate the die1 periodicity of pheromonal communication.
