Study on the bacterial midgut microbiota associated to different Brazilian populations of Lutzomyia longipalpis (Lutz & Neiva) (Diptera: Psychodidae) Neotropical Entomology
Gouveia,Cheryl; Asensi,Marise D.; Zahner,Viviane; Rangel,Elizabeth F.; Oliveira,Sandra M.P. de.
The bacterial community associated with the midgut of three Brazilian Lutzomyia longipalpis (Lutz & Neiva) populations, two from endemic areas for visceral leishmaniasis (Jacobina, Bahia State and São Luís, Maranhão State) and one from a non-endemic area (Lapinha Cave, Minas Gerais State), was identified. Five groups, 35 females each, from each population were separated; a total of 175 females per collecting area were analyzed. The species identification was based on molecular and traditional bacteriological methods. All bacteria were either affiliated to non-Enterobacteriaceae, such as Acinetobacter, Burkholderia, Flavimonas, Pseudomonas and Stenotrophomonas, or and to Enterobacteriaceae, such as Citrobacter, Enterobacter, Escherichia, Klebsiella,...

Methodology for bioassay entomopathogenic Bacillus against sand fly (Diptera, Psychodidae, Phlebotominae) larvae Zoologia
Wermelinger,Eduardo Dias; Zanuncio,José Cola; Rangel,Elizabeth F.; Cecon,Paulo R.; Rabinovitch,Leon.
The objective of this research is to present a method to bioassay entomopathogenic Bacillus species against sand fly (Diptera, Psychodidae, Phlebotominae) larvae. The vector Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera, Psychodidae, Phlebotominae) and some Bacillus strains were used in laboratory to develop this method. Some characteristics of this method are commented and the importance to develop a standard method to test pathogenicity of Bacillus species against phlebotomine larvae is also discussed.

Toxicity of Bacillus species to larvae of Lutzomyia longipalpis (L. & N.) (Diptera: Psychodidae: Phlebotominae) Anais da SEB
Wermelinger,Eduardo D.; Zanuncio,José C.; Rangel,Elizabeth F.; Cecon,Paulo R.; Rabinovitch,Leon.
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.
