Abstract:Nearly 8000 acres in Illinois were treated in 1966 with 4 low-volume aerial applications of 80% wp carbaryl at a rate of 1 lb per gallon per acre, to determine the effect of such applications on an isolated infestation of Popillia japonica Newman. The size of particles deposited on cards and foliage varied within a given tank of spray mixture. Percentage kill of caged adult beetles exposed to residues (1-7 days old) on foliage was high, but some adults lived more than 24 hours. Most beetles (95%) exposed to 8 to 14-day-old residue died in 3 days, and most beetles exposed to 21 to 28-day-old residues died in 7 days. Captures of adult beetles in bait traps averaged 74 per trap in 1966, 2 per trap in 1967, and II per trap in 1968 throughout the area. In 1967 and 1968, when no sprays were applied, the populations of beetles were greatly reduced, but we could not determine how much of the reduction should be attributed to the treatment applied in 1966 (though we believe it was a major factor), since seasonal factors such as extreme deficiency in rainfall (as in 1966) influence the size of populations.
