Evaluation of trapped beetle repellency, various trap heights, and a s
tring pheromone dispenser were tested on 2 golf courses for capture of
Japanese beetle, Popillia japonica Newman, adults. Beetle captures in
creased significantly when trapped beetles were removed daily from tra
ps, No significant differences in captures were found among traps with
12.1-, 18.9-, or 7.6-liter collection containers, and there was no in
teraction between beetle removal and collection container size. Trece
traps with funnel rims at a height of 13 cm above ground level capture
d significantly more beetles than traps with funnel rims at round leve
l or at 90 cm above ground level. Numbers of beetles collected in trap
s with a polyvinyl chloride coated string pheromone dispenser were sim
ilar to numbers captured in traps using a standard Trece rubber septum
pheromone dispenser.
