Abstract
Surface-layer application of a commercial formulation of Bacillus thuringiensis Berliner was evaluated for controlling Indian meal moths, Plodia interpunctella (Hübner), and almond moths, Ephestia cautella (Walker), in corn stored in 2-m3 (ca. 60-bu) capacity bins. The bins were artifically infested, and efficacy was monitored by making weekly moth counts, collecting larvae and pupae in strips and spools of corrugated paper, periodically assaying samples of the grain, and evaluating insect feeding damage at the end of the storage season. The test method proved to be satisfactory, and doses of 100, 125, and 150 mg of B. thuringiensis formulation/kg of com in the 10-cm-deep surface layer reduced moth populations by ≥92%, reduced insect feeding damage by >82%, and prevented webbing of the grain surface.This publication has 1 reference indexed in Scilit:
