Abstract
DUQUE, JONNY E and NAVARRO-SILVA, MARIO ANTÔNIO. Larval susceptibility of Aedes (Stegomyia) albopictus (Diptera: Culicidae) from Sao Paulo, Brazil to Bacillus thuringiensis var israelensis H-141. Rev. Colomb. Entomol. [online]. 2005, vol.31, n.2, pp.199-201. ISSN 0120-0488.
The susceptibility of Aedes albopictus larvae, originating from "Vale do Ribeira llha Cumprida" Sao Paulo, Brasil. was determined under laboratory conditions. The product used was Bacillus thuringiensis var israelensis H-14 Vectobac-AS with 1,200 internacional toxic units (TU) per milligram. An Aedes aegypti Rockefeller colony from CDC (Center for Disease Control) of Puerto Rico was used as a reference. Lethal concentrations determined for Ae. albopictus were LC50= 0.12 ppm and LC95= 0.28 ppm and for the reference species Ae. aegypti they were LC500.07 ppm and LC95 0.17 ppm. It is concluded that Ae. albopictus presented a different response to the bioinsecticide than Ae. aegypti.
