Seasonal oviposition activity of Aedes (Stegomyia) aegypti (Diptera: Culicidae) in San Miguel de Tucumán, Northwestern Argentina

Abstract

Aedes aegypti has recolonized many areas of Argentina. The purpose of this study was to determine the seasonal patterns of oviposition activity of this mosquito vector and the association between oviposition and climate in an urban area of Tucumán province with a history of dengue transmission. We collected 9,476 eggs by ovitraps in San Miguel de Tucumán with the highest abundance of eggs observed in Ciudadela and El Bosque neighborhoods. Peak oviposition activity by Ae. aegypti occurred in the summer. The number of eggs laid was positively correlated with temperature and precipitation levels.
