An area of some 16,000 acres, or roughly 1/3 of the cotton acreage in Reeves County, Texas, in 1965 was involved in an insect-control program in which 5 types of electric insert traps were utilized to capture lepidopterous insects, primarily the bollworm, Heliothis zea (Boddie) , and the cabbage looper, Trichoplusia ni (Hũbner). However, 4 designs were used in more than 90% of the acreage. Generally, the traps were placed about 550 ft apart on the periphery of a field. The comparison of trapping effectiveness of the 4 major designs of electric insect traps with a standard trap (Gardner fan-type) indicated that: (1) when nightly moth catches averaged less than 100 bollworm or cabbage looper moths, differences in effectiveness were not statistically significant; (2) when nightly catches of bollworm and cabbage looper moths ranged from 120 to 300+ moths per night during the latter part of the season, the differences in the catches of cabbage loopers were not statistically significant. However, though the nightly catches of bollworms by the Agri-Light and Lethalite traps were equal to those of the standard trap, the standard trap caught significantly more moths (18.9% and 69.4%) than the homemade and Agri-Light LS-15 traps, respectively. When the number of Lethalite and LS-15 traps was doubled, bollworm catches increased as much as ]09% and 69%, respectively; catches of cabbage looper moths increased as much as 150% and 96%, respectively.
