Abstract

Laboratory experiments were conducted to measure the susceptibility of larvae of the sandfly Phlebotomus papatasi Scopoli to the insect pathogen Bacillus sphaericus applied to the larval breeding medium. B. sphaericus had no effect on larvae aged 30 ± 2 days old, but larvae aged 13 ± 2 and 20 ± 2 days were highly susceptible and a clear dose response effect was detected. When B. sphaericus was left in the rearing medium for 18 days there was a significant increase in larval mortality, indicating persistence and possibly recycling. The results support the feasibility of employing B. sphaericus in the integrated control of sandflies.
