Abstract
The effectiveness of bait traps to capture adult Glischrochilus quadrisignatus (Say) was evaluated for 5 years. Traps comprised of 2.85-1. cans baited with ripe bananas, an insecticide, and a small amount of water captured from 21000 to 58000 beetles/trap when placed around the periphery of tomato fields at a density of 5 traps/ha from spring to fall. The largest numbers were trapped during the 5-week interval from mid-July to mid-August when newly developed adults emerged from the soil.
