| Summary: | ABSTRAK
Bioinsecticides, mainly developed from Bacillus tburingiensis H-I4 and B. spbaericus 1593, seems to be most promising alternatives to chemical insecticides for controlling mosquito-borne diseases, due to their safety and specificity.
The objectives of the present research was to test the sensitivity of Aedes aegypti mosquito larvae to standard powders of B.f. H-14 (IPS 82) and B.s. 1593 (RB 80) under laboratory conditions following procedures standardized by the Institute Pasteur (Paris).
Probit analysis of the mortality data of the test insects indicated that Ae. aegypti larvae were much more sensitive to.B. t. H-14 than to.8.s 1593. It was suggested, therefore, that B.t. H-14 formulations could be alternatively applied to Ae. aegypti control.
