Bioticand abiotic factors have been reported to affect the larvicidal efficacy of Bacillus thuringiensis israelensis (Bti) and Bacillus sphaericus (Bs), although the extent to which they are affected has been poorly documented. This paper studies the effect of sunlight exposure on the efficacy of a new larvicide formulation based on both Bti and
1The Bacterium and Their Crystalline Parasporal Bodies. Bacillus thuringiensis is a bacillus-shaped, Gram-positive, aerobic, and spore-forming bacterium that lives in numerous habitats, including soil, water, plant leaves, dead insects, and necrotic animal tissues (Höfte and Whiteley 1989; Knowles and Dow 1993; Roh et al. 2007; Thisis particularly important for any pesticide formulations to be used in drinking-water in containers in view of the direct exposure of humans. 5. CONCLUSIONS. Bti itself is not considered to pose a hazard to humans through drinking-water. Bacillusthuringiensis subsp. israelensis is the most widely used microbial control agent against mosquitoes and blackflies. Its insecticidal success is based on an arsenal of toxins, such as Cry4A, Cry4B, Cry11A, and Cyt1A, harbored in the parasporal crystal of the bacterium. A fifth toxin, Cry10Aa j0VUk3Z.
