Aqueous and dust applications of a lactose formulation of a granulosis virus (ca. 3.2×l07 capsules/mg) were equally effective in protecting wheat against Plodia interpunctella (Hübner), and a dose of 1.875 mg of formulated virus/kg of grain gave good control. Treatment of the surface layer of wheat or corn to a depth of 100 mm was more effective than treatments applied to depths of 33 or 67 mm and was almost as effective as treating the entire grain mass. Grain in the treated layer need not be uniformly treated since the level of insect mortality was unchanged whether the treatment was applied to every kernel or to only part of the kernels.
