dc.description.abstract | Blueberry spanworm, Itame argillacearia (Packard), is an important defoliator of wild (syn. ‘lowbush’) blueberry in north-eastern North America. Identification of I. argillacearia sex pheromone(s) could be useful for monitoring, mating disruption or mass trapping, as a way to improve integrated pest management programs for this pest. Thus, the main goal of this study was to identify sex pheromone(s) of I. argillacearia. The courtship, mating and oviposition patterns of I. argillaceara, was studied in the laboratory. GC/MS, GC/EAD and EAG analysis of pheromone gland extracts, in combination with y-tube experiments and two field trapping studies confirmed the chiral-alkenyl-epoxide, (3R,4S)-epoxy-(Z,Z)-6,9-17:H and tri-ene, (Z,Z,Z)-3,6,9-17:H as the major female-produced sex pheromone components. Contech Wing traps® placed at canopy level were effective for capturing male I. argillacearia moths. | en_US |
