Abstract
Studies were undertaken to determine the effect of the control of tarnished plant bug, Lygus lineolaris (P. de B.), on birdsfoot trefoil, Lotus corniculatus L., seed production. The study of populations of the tarnished plant bug in six fields in New York throughout the growing season indicated that a large increase in numbers of this insect occurred toward the last of June. Insecticide applications were made experimentally in mid-June to prevent this build-up. A method was developed whereby the seed yields in pounds per acre could be estimated by counting the number of legumes persent in 20 one-square-foot areas. Treatments with aldrin, parathion, DDT, and toxaphene significantly increased seed yields from birdsfoot trefoil when applied to control the tarnished plant bug. These increases in seed yields occurred in experiments having check plots that averaged 16 or more tarnished plant bugs in 25 net sweeps. However, in some untreated plots the tarnished plant bugs were considerably more numerous.
