WERMELINGER, Eduardo D. et al. Toxicity of Bacillus species to larvae of Lutzomyia longipalpis (L. & N.) (Diptera: Psychodidae: Phlebotominae). An. Soc. Entomol. Bras. [online]. 2000, vol.29, n.3, pp.609-614. ISSN 0301-8059.

A study was conducted to compare the susceptibility of third instar larvae of Lutzomyia longipalpis (L. & N.) (Diptera: Psychodidae: Phlebotominae), the vector of the American visceral leishmaniasis to two strains of Bacillus thuringiensis serovar israelensis, one strain of Bacillus sphaericus (all pathogenic to Diptera Culicidae) and a strain of B. thuringiensis ser. morrisoni (pathogenic to larvae of Anticarsia gemmatalis (Hübner) (Lepidoptera: Noctuidae)). Larvae of L. longipalpis showed similar susceptibility to the two strains of B. thruringiensis ser. israelensis, while B. sphaericus and B. thuringiensis ser. morrisoni showed low and no larvicidal effect to this vector, respectively.

Keywords : Insecta; microbial control; leishmaniasis.
