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

Abstract

Aedes aegypti (L.) (Diptera: Culicidae) has recolonized many areas of Argentina. The purpose of this study was to determine the seasonal patterns of oviposition activity for this mosquito vector and the association between this factor and climate in an urban area (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 the 2 neighborhoods Ciudadela and El Bosque. Peak oviposition activity by Ae. aegypti occurred in the summer. The number of eggs laid was positively correlated with temperature and precipitation levels.
