Toxicidad Y Efecto Esterilizante de Algunas Combinaciones de Los Quimioesterilizantes Sexuales Afolato Y Tepa Sobre Musca Domestica (L) 1

Abstract

Spanish

Chemical sexual sterilants present properties which make them useful for control or eradication of harmful insects. Because the combined action of two or more of them has apparently not been studied, neither from the toxicological nor from the sterilizing point of view, a research was carried out with the objective of determining this action.

For this purpose the house fly Musca domestica (L.) was reared and maintained in the laboratory and the pupal stage was treated topically with some combinations of Apholate and Tepa.

The results obtained indicate that under the conditions of this experiment, both products exhibit toxicity, being the one observed with Tepa greater, and that the joint supply activates the lethal effect. Further, the toxic action in reference can be represented by means of a statistical model. The combinations of Apholate and Tepa utilized, have an antifertilizing action on the flies emerged from the treated pupae and at the same time reduce the longevity, being this effect greater in the males than in the females.
