Abstract
MONTADA DORTA, Domingo; LEYVA SILVA, Maureen; CASTEX RODRIGUEZ, Mayda and SILVA LEYVA, Yenly. Efficacy of indoor treatment with cypermethrin, lambda-cyhalothrin and chlorpiriphos for the regulation of Aedes aegypti in the City of Havana. Rev Cubana Med Trop [online]. 2010, vol.62, n.3, pp.230-236. ISSN 0375-0760.
INTRODUCTION: in dengue outbreaks or epidemics, the chemical pesticides play a fundamental role to control disease-borne adult mosquitoes and to support the Vector Control program in Cuba. OBJECTIVE: to find out the effectiveness and the efficiency of insecticidal formulations in use for the control of Aedes aegypti mosquito in three strains from the City of Havana. METHODS: bioassays followed the methodology recommended by the World Health Organization. Efficacy and efficiency were compared in the studied insecticides between the cold spraying and the thermal spraying. A standardization test was applied to verify the nature of each variable; one three-factor ANOVA to see any differences among the mortality means and the Kruskal-Wallis test to find out difference among the mortality values for each type of treatment with respect to the preparation of one liter of mixture (efficiency), for a significance level of p< 0,05. RESULTS: When comparing the mortality figures reached with both types of treatment, it was evinced that there was a highly significant difference between them, the most favourable results corresponded to thermal spraying, which proved the efficacy of this treatment and its efficiency (effectiveness/cost). CONCLUSIONS: there exists a highly significant difference between the formulations, which favors Galgothrin 25 EC.
