Efficacy of Selected Insecticides for Plant Bug Control in Arkansas, 2004

摘要

RESEARCH PROBLEM - The tarnished plant bug [Lygus lineolaris (Pialisot de Benuvois)] is a major pest of cotton. The insect causes damage by feeding on plant tissue and can reduce yields if left uncontrolled. The purpose of this experiment was to testthe effectiveness of 36 treatments in three locations for control of the tarnished plant bug. BACKGROUND INFORMATIONTarnished plant bugs are troublesome pests in cotton (Hollingsworth et al., 1995; Kharboutli et al., 1998; Robbins et al., 1998). Plant bugs feed on a variety of plant fruiting structures including squares, blooms, and bolls. Typically they damage youngsquares by puncturing and feeding on the tissue. In white flowers the damage will cause a "dirty" appearance from bugs feeding on the anther of the bloom. When plant bugs feed on young bolls, they puncture the boll wall, which can result in damaged lintand seed. Boll feeding usually results in the formation of wart-like scars and causes off-color lint. The purpose of the experiments was to see how well various chemicals would perform with regard to plant bug control.
