Abstract The present work designed to study the mutagenic effect of three insecticides: zolone, cidial and hostathion on Musca domestica usmg two protocols, dominant female sterility and isozymes variations for the four enzymes: Me, a-Gpdh, Ldh and Mdh using starch gel electrophoresis. It is clear from all the data gained by these protocols that the three used insecticides have no effects on the fertility of females and have no mutagenic effects on Me enzyme. On the other hand, they have mutagenic effects on a-Gpdh, Ldh and Mdh enzymes when adult Musca domestica flies were treated. Key words: Musca domestica - Dominant female sterility - Isozymes variations Malic enzyme (Me) aGlycerophosphate dehydrogenase (a-Gpdh) - Lactate dehydrogenase (Ldh) - Malate dehydrogenase (Mdh). |
