MOLECULAR STUDIES ON THE EFFECT OF SOME NATURAL BIOLOGICAL PESTICIDES IN EXPERIMENTAL ANIMALS

Abstract

Most of the chemicals that are used as pesticides are not

highly selective but are generally toxic to many nontarget species, • including humans, and other desirable forms of life that coinhabit the environment. In recent years, it has become increasingly apparent that exposures to pesticides far from the source of application are also possible. This results from the translocation of the chemicals from their sites of application through the various media of the environment. The present study was conducted to investigate the genotoxic potentiality of two biopesticides Avermectin and Diple 2x (Bacillus thuringiensis"B.f'), registered as natural pesticides in Egypt. Different assays were employed in this work including cytological and molecular techniques.
