BISSET, Juan; MARQUETTI, . María del Carmen; LEYVA, Maureen y RODRIGUEZ, Magdalena. Distribution and size of adult Aedes aegypti associated with the breeding sites. Rev Cubana Med Trop [online]. 2008, vol.60, n.1, pp. 0-0. ISSN 1561-3054.
INTRODUCTION: At present, environmental studies are conducted to find new strategies for the control of Aedes aegypti. OBJECTIVES: To classify Aedes aegypti breeding sites into various categories and to determine their risk factors; to determine the size of females from pupas collected in situ and to learn about the vector distribution. METHODS: this research work was carried out in Playa municipality. All the premises and water containers were inspected from where the pupas were taken to determine the size of emerged females. RESULTS: Containers were classified into 5 categories: water storage containers, artificial containers left in house yards, troughs for animals, natural breeding sites and tyres. Two thousand five hundred and six premises were visited and inspected and 57 of them (2.27 %) were positive to the mosquito for a index per house of 2.27; a container index of 0.53 and Breteau´s index of 2.79. The highest average measures in wing length of 332 females and the highest risk factor values were found in troughs for animals and tyres (3.07 ± 0.104 y 3.31 ± 0.95 mm) for an average of 2.95 ± 0.25 mm, and 2.15 and 5.31 respectively. No significant difference was found (ANOVA test, p= 0.09) when comparing the female wing length measurements gathered from the different container categories. CONCLUSIONS: Aedes aegypti females showed variable sizes. This vector was spread all over the studied area.
