DIEGUEZ FERNANDEZ, Lorenzo; CABRERA FERNANDEZ, Sonia María  and  RODRIGUEZ DE LA VEGA, Ricardo. Aedes (St.) aegypti infestation of troughs for animals in a health area. Rev Cubana Med Trop [online]. 2009, vol.61, n.1. ISSN 0375-0760.

INTRODUCTION: Aedes aegypti, important vector of dengue/hemorrhagic dengue, prefer the urban environment for its very unstable development since it provides it with a number of possibilities for its survival. OBJECTIVES: to evaluate the entomological and epidemiological contributions of troughs for animals to Ae aegyti infestation in an urban health area in Camagüey province, Cuba. METHODS: The total number of troughs positive to the mosquito, broken down by type of animal using it, as well as the percentage of positive troughs taken as specific reservoir index were estimated. Also, all the troughs containing pupas and the total number of pupas per type of trough were determined; each of them was characterized. RESULTS: it was observed that troughs represented 4.62 % of positive sites, with a specific reservoir index equals to 0.74 %; 6 troughs were used by chicken, 5 by rabbits and one by monkeys and the other by dogs. Six pupas were detected (0.46 pupa/trough). CONCLUSIONS: these reservoirs that are mainly placed outdoors in shady areas, though they did not give rise to a substantial number of foci, one must be taken it into account to designing new control strategies, which will help in assuring the non-existence of residual eggs in dwellings.
