Laboratory Studies with Bacillus thuringiensis Berliner and Its Possible Use for Control of Plodia interpunctella (Hbn.)1

Abstract

The Indian-meal moth, Plodia inter punctella (Hbn.), is a serious pest of stored grain and cereal products and is often encountered in Nebraska in both stored wheat and corn. In many elevators and storage bins, populations of this insect develop annually and control measures are required. Infestations developing in bins of wheat and shelled corn are usually limited to the surface areas and the exposed grain mass. When unshellcd corn is infested, the infestation is often found throughout the entire grain mass. In addition to attacking stored wheat and corn, Metcalf et al. (1951) report that this insect feeds on dried fruits, nuts, seeds, roots, herbs, and many other products.
