In comparison to chlorinated hydrocarbons insecticides of the compound classes organophosphates, carbamates and pyrethroids were tested according to an earlier described soil-test in the laboratory. The following termite-species were used: Heterotermes indicola, Reticulitermes santonensis and in addition Reticulitermes flavipes, Reticulitermes lucifugus, Reticulitermes speratus and Coptotermes formosanus (Rhinotermitidae). The method gives reliable results. Criteria for evaluation are mortality and penetration of the termites into the treated soil. According to this test organophosphates, specially phoxim, have a good potential to replace chlorinated hydrocarbons.
