Resumen
CARDENAS CASTRO, Estrella; ROZO BAUTISTA, Álvaro y LUGO VARGAS, Ligia. Larval Mortality in Culexquinquefasciatus and Anopheles albimanus (diptera: culicidae), Caused with a Bacillus sphaericus (bacteria: bacillaceae) Granulated Product in Experimental Conditions. Rev. Med. Vet. [online]. 2012, n.23, pp.23-32. ISSN 0122-9354.
The purpose of this study was to assay a series of concentrations of a granulated product prepared with Bacillus sphaericus on Culexquinquefasciatus and Anopheles albimanus larvae in laboratory conditions. Eleven concentrations (20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 500 ppm) were used on An. Albimanus larvae and eight concentrations ten times smaller (2, 4, 6, 8, 10, 12, 14, 16 ppm) were used on Cx. quinquefasciatus larvae. Sixty (60) larvae and a control with 20 larvae were used per concentration. The time of exposure was of 48 hours at a laboratory temperature of 28 ± 2 °C. LC50 and LC95 were determined through the Probit tests. A LC95 of B. sphaericus was found between 6,45 and 7,28 ppm for Cx. quinquefasciatus larvae; whereas LC95 was observed between 450.56 and 466.76 ppm in An. albimanus larvae.
