CAMARGO-NEVES, Vera L F de; RODAS, Lílian A C; CABRAL, Gisele  and  PAULIQUEVIS JR, Clóvis. Evaluation of Lambdacialotrin efficacy for Lutzomyia longipalpis control. BEPA, Bol. epidemiol. paul. (Online) [online]. 2007, vol.4, n.43, pp. 04-11. ISSN 1806-4272.

The authors present results from a study on evaluation of Lambdacialotrin (Demand 10 CS®, Syngenta) efficacy for density control of Lutzomyia longipalpis, obtained from two cities (Araçatuba and Birigui) of the region of Araçatuba, in the west of the State of São Paulo which are under insecticide pressure since 1987. Biologic wall proof, according to WHO guidelines were performed: in 0, 3 and 30 days after insecticide application. Lambdacialotrin was applied in 0,03g ia./m wall concentration evaluating the possible need to add to the solution the adhesive spreading aide Iharaguens® (Ihabras SA), obtaining the volume of 50 mL of the product for 8L of the solution. This mixture was applied in three stripes, with an area of 2,10m2 each, employing pulverizing pump of previous compression, model Guarany®. Operational procedures were evaluated, as homogeneity of the syrup, beak clotting, odor and stain and trickling effects. Adhesive spreading aide was added, when trickling of the syrup was observed in the area. Efficacy was evaluated by mortality rate obtained after 24 hours, after exposition of 15 to 20 specimens/cone of L. longipalpis, during one hour. Difference in the susceptibility of the strains of the vector was noted, depending on wall finishing, number of days after application and strain origin.
