Abstract
Field studies were conducted to determine the effect of (Z)-11-hexadecen-1-ol (Z11-16∶ OH) on capture of tobacco budworm (TBW),Heliothis virescens (F.), males when added to two-component (HV-2) and six-component (HV-6) pheromone blends dispensed from a polyvinyl chloride (PVC) substrate. Numbers of males caught in traps baited with PVC dispensers containing 0.25% Z11-16∶ OH, relative to total pheromone content, were significantly higher than numbers caught with dispensers containing noZ11-16∶ OH. Catches of TBW were also increased significantly in some tests whenZ11-16∶ OH was formulated in the bait at a 1% concentration. Catches were significantly reduced with dispensers containing 5.95%Z11-16∶ OH compared with those containing noZ11-16∶ OH. There were no differences in catch between traps baited with HV-2 vs. HV-6 or HV-2 + 0.25%Z11-16∶ OH vs. HV-6 + 0.25%Z11-16∶ OH when formulated in PVC substrate.
