Distribución espacial y temporal de los sitios de cría de Aedes albopictus y Aedes aegypti (Diptera:culicidae) en Pinar del Río, Cuba.

Introduction. The spread of dengue is attributed to the expanding geographic distribution of the four serotypes of dengue and the spread of its mosquito vectors, Aedes aegypti and Aedes albopictus. Ae. aegypti reinfestations began in the 90s in several provinces of Cuba along with the introduction of Ae. albopictus in 1995. Objective. Determine the spatial and temporal distribution of Ae. aegypti and Ae. albopictus breeding sites in Pinar del Río province, Cuba from 2003-2010. Materials and Methods. Larval collections were made throughout the province, following the methodology of the Ae. aegypti control program. Results. Ae. aegypti presence increased in 13 (92.8%) of all municipalities in the province in 2010, while Ae. albopictus was found in 100% of the municipalities in the province in 2008. Both species were distributed in significant quantities across municipalities located in the south-central part of the province, in areas with: grassy plains, major urbanization, and areas with main transport routes. Increased mosquito presences were found from July to October, coinciding with higher positive values in standing water in ground level tanks and in small artificial containers, although at different rates. Ae. albopictus showed a preference for breeding in larvae traps. Ae. aegypti and Ae. albopictus showed both low association between them and with other species of mosquitoes. Conclusion. Ae. albopictus populations are expected to become endemic in the province, replacing Ae. Aegypti, in a large part of the province, requiring continuing studies by the researchers.
