Resumo: Sugarcane bagasse is a renewable resource that can be used to produce biopesticide for the control of mosquito vectors. In the present study, we demonstrated that cane processed bagasse could be used to produce Bacillus thuringiensis serovar israelensis (Bti) for control of mosquito vectors viz: Culex quinquefasciatus, Anopheles stephensi and Aedes aegypti. Biochemical studies indicated that the Bti spore/crystal toxins produced from the test culture medium (Bagasse, BG + Soybean, SB) are higher than that from the conventional medium (Nutrient Yeast Extract Salt Medium, NYSM). The bacteria produced in these media (NYSM, BG, SB, BG+SB) were bioassayed against the mosquito species and the toxic effect was found to be effective. Cost-effective analysis indicates that the use of BG and SB, as bacterial culture medium, is successful and economical, for production of this mosquito pathogenic bacillus.
