Trap crops, along with delayed uniform planting and pinhead square treatments, greatly reduced overwintered boll weevil populations in a Laveen, Arizona community-wide IPM program. Thirty four trap crops, planted fifteen days ahead of the regular crop, had as many as 15000 damaged plants peracre before insecticide treatments were initiated. Five insecticide applications at 3-day intervals were used to destroy weevils before the trap crops were plowed under at the time pinhead square treatments were initiated in regular planted fields. Damaged square infestations were 2 to 11 times lower throughout the season in 1987 compared to 1986 while average lint yields increased from a low of 840 pounds in 1985 to 1344 pounds in 1987.
