Studies on the mode of action of insecticides (Orthoptera: Blattidae).

Abstract

Application of aldrin, endrin, lindane and methoxychlor induces pathology in the alimentary canal, Malpighian tubules, fat bodies and central nervous system of the cockroach Periplaneta americana Linnaeus. The pathology is characterized by the development of identical features and does not indicate which insecticide has been used. In view of the development of identical pathology caused by the action of insecticides and the loss of water from the body of the cockroaches, it is supposed that the insecticides by their action cause the withdrawal of water from the tissues and this withdrawal of water in turn induces pathology.
