ABSTRACT

Introduction. Aedes aegypti surveillance has largely relied upon larvae indices however this has been strongly criticized as they provide scanty information to determine dengue risk of transmission.
Objetives. To determine the most productive Ae. aegypti pupae water containers, the emerging daily numbers of Ae. aegypti adult females, as well as the mosquito spatial distribution in the area of study.
Material and Methods. A survey was carried out in the whole La Lisa municipality to collect the immature mosquito stages in different water containers. Daily numbers of emerging females was calculated, and temperature and rainfall data were also collected.
Results. A total of 527 water containers had figures of 1268 Ae. aegypti (986 larvae and 282 pupae) during the year of study. They were distributed in 53 different habitats, lower tanks or tins for water storage were the most productive for the pupae stages in the study. The highest adult female emerging rate occurred during July-August and the lowest between October-December. A significant positive relation was found for temperature, rainfall and the number of habitats but not for daily emerging females.
Conclusions. The study proposes to use pupae surveillance for the Ae. aegypti control program in Cuba to focus on the most productive mosquito water containers.
