Technique for Evaluating Residual Toxicity of Pesticides to Motile Insects

Abstract
A-general method useful in evaluating residual toxicity of pesticides to motile arthropod species while minimizing pesticide fumigation effects is described. Data obtained using the method are presented. Both the pesticide tolerance to acephate and longevity are compared for adults of the citrus thrips, Scirtothrips citri (Moulton); Aphytis melinus DeBach, an aphelinid parasitoid; and Cryptolaemus montrouzieri Mulsant, a coccinellid predator.
