Interpretive Summary: The Japanese beetle is a serious pest of horticultural crops throughout most of the eastern United States, and an important quarantine concern in areas where it still may become established. Trapping systems have long been used to follow changes in the beetles distribution and to help suppress beetle populations. There is a continuing interest in examining the effects of new formulations of lures and trap placement on the captures of Japanese beetle adults. It was found that daily removal of beetles from trap canisters, and a funnel height of about 13 cm above the ground resulted in the greatest trap efficiency. In addition, it was shown that a new polyethylene coated string dispenser for Japonilure, the Japanese beetle pheromone, was comparable to standard pheromone dispensers now in use. The information obtained from this study will allow scientists, regulatory officials, and homeowners working with Japanese beetle lure systems to operate those traps with new formulations of pheromone and under conditions that maximize captures.

Technical Abstract: Effects of removal of trapped beetles, various trap heights, and a new string pheromone lure were tested on a golf course for capture of Japanese beetle (Popillia japonica Newman) adults. Captures increased significantly when trapped beetles were removed daily from traps. There were no significant differences in captures between traps with 7.6, 18.9, and 121 liter collection containers and standard TreceR traps. 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. The numbers of beetles collected in traps with a new polyethylene coated string pheromone dispenser were not significantly different than those from traps utilizing a standard Trece rubber septa pheromone dispenser.
