Susceptibility of Angoumois Grain Moths to Bacillus thuringiensis123

Abstract

Larvae of Sitotraga cerealella (Olivier) were susceptible to Bacillus thuringiensis Berliner incorporated into a ground diet in gelatin capsules. Doses of 125 and 250 µg of formulated B. thuringiensis/g of diet gave 90–100% control. On wheat, B. thuringiensis did not significantly reduce F₁ adult emergence but the 2nd generation was significantly reduced.
