Evaluation of Trapped Beetle Repellency, Trap Height, and String Pheromone Dispensers on Japanese Beetle Captures (Coleoptera: Scarabaeidae)
Date of Original Version
Evaluation of trapped beetle repellency, various trap heights, and a string pheromone dispenser were tested on 2 golf courses for capture of Japanese beetle, Popillia japonica Newman, adults. Beetle captures increased significantly when trapped beetles were removed daily from traps. No significant differences in captures were found among traps with 121-, 18.9-, or 7.6-liter collection containers, and there was no interaction between beetle removal and collection container size. Trece traps with funnel rims at a height of 13 cm above ground level captured significantly more beetles than traps with funnel rims at ground level or at 90 cm above ground level. Numbers of beetles collected in traps with a polyvinyl chloride coated string pheromone dispenser were similar to numbers captured in traps using a standard Trece rubber septum pheromone dispenser.
