CHANG CAMERO, Yalina et al. Aedes aegypti larvae found in reservoirs during the operational use of Bactivec biolarvicide. Rev Cubana Med Trop [online]. 2013, vol.65, n.1, pp.90-98. ISSN 0375-0760.

Introduction: the detection of breeding sites of Aedes aegypti is an important factor for the implementation of control strategies. Objective: to identify the reservoirs where Aedes aegypti mosquito was observed during the period of operational use of Bactivec larvicide in Mariel municipality. Methods: during the period of operational use of Bactivec biolarvicide from May 2008 to 2009, breeding sites positive for this mosquito were searched for in urban and semiurban areas of the people's councils Boca/Mojica/Henequen, Mariel, Sabana/Zayas, Quiebra Hacha y Cabanas. All the positive reservoirs were identified in those areas where they were collected and the percentage of involvement of each type of reservoir with respect to the total amount of positive samples was estimated. Results: thirty five types of reservoirs used as the breeding site of the mosquito were identified. The useless disposable reservoirs accounted for 54.28%, water storage reservoirs for 14.29 and the useful ones for 11.43 %. The presence of the dengue vector in natural breeding sites and in polluted waters reached 8.57 %. Conclusions: the useless reservoirs turned to be the most used by the Culicidae for egg-laying, following by the water storage ones which were treated with biolarvicide. Aedes aegypti was heavily present in polluted waters, which were also treated with Bactivec.
