Biological effect of Bacillus thuringiensis israelensis (Antrol) to house fly

Abstract

The effects of concentrations of bacterial suspension of Bacillus thuringiensis israelensis (Antrol), against adults and larvae of Musca domestica L. by treating their food was conducted under laboratory conditions.Results showed that treating the adults’ food with concentration between 50-1000 ppm led to accumulated mortalities percentages depending on concentration and time, mortalities percentages were 77.78-88.89 after five days of treatment.Results of treating M. domestica larval food by above concentrations led to accumulated mortalities depending on the concentration ranged between 53.53-77%, various mal formation, such as blacking and shrinking the body were depicted. Reduction in pupal weight and reduction in female fecundity and hatchability of the egg compared with control treatment were registered due to the larval food treatment.
