Abstract

Spatial and temporal distribution of breeding sites of Aedes albopictus (Diptera: Culicidae) in Havana, Cuba.

Abstract

Introduction: Aedes albopictus is a mosquito native to the forests of Southeast Asia which has spread to all continents in recent decades. The species was first reported in Cuba in the province of Havana in 1995. Objective: determine the spatial and temporal distribution of breeding sites of Ae. albopictus in the municipalities of the province of Havana in 2011 and 2012. Methods: sampling was conducted of all containers with water in residential areas and vacant lots of urban and suburban zones of all municipalities in the province of Havana. Results: presence of Ae. albopictus was reported in 13 of the 15 municipalities in the study area, revealing not only its introduction but also its spread in the area. The greatest presence of Ae. albopictus was found in peripheral municipalities like Playa, La Lisa, Boyeros, Arroyo Naranjo, Cotorro, Guanabacoa and Habana del Este. An increase in the total number of samples was observed in 2012 with respect to 2011. In both years there was an increase from June to October. Again in both years, the greatest number of samples of Ae. albopictus with more than one culicid species was found in the rainy season (May to September). Conclusions: the presence and distribution of Ae. albopictus in Havana was confirmed. Favorable ecological conditions and the availability of breeding sites play a decisive role in such presence and distribution.
