The efficacy of Dryacide (diatomaceous earth coated with silica aerogels) on wheat was tested in the laboratory against adult and immature stages of 4 species of Coleoptera and against immature stages of 1 species of Lepidoptera. The minimum effective level of Dryacide increased in the following order: immature Ephestia cautella and immature Tribolium castaneum; immature Rhyzopertha dominica; adult R. dominica and adult T. castaneum; adult Sitophilus oryzae; adult Sitophilus granarius; immature Sitophilus sp. When treated wheat was milled in the laboratory without prior cleaning, less than 3 percent of the Dryacide carried over into the flour. Commercial cleaning of wheat removed about 98 percent of Dryacide, and none could be detected in the flour. Dryacide treatment did not affect flour quality as determined by the volume of sponge cakes and the production of carbon dioxide by fermenting dough.
