title: The influence of Bacillus sphaericus on the biology and histology of Phlebotomus papatasi.
abstract: This work was achieved to study the impact of B. sphaericus treatment on some biological aspects of P. papatasi. Contaminated larval food with B. sphaericus (strain-2362) in different concentrations was offered in the laboratory for P. papatasi and also the latent effect on the fecundity of survived females from previously treated larvae. There was a decrease in the survived numbers of immature stages and adults correlated to the concentrations, while there was no obvious change in the larval and pupal durations compared to the control. The fecundity of females survived from previously treated larvae, was sharply decreased. Many variations was noticed in the examined tissues of mid-gut, fat tissues, and Malpighian tubules, although no bacteraemia was detected.
