Oviposición diaria de Aedes aegypti en Orán, Salta, Argentina

Abstract

The study aimed to determinate the maximum daily peak of Aedes aegypti oviposition in the city of Oran, northwestern Argentina. Biweekly samplings were taken between November 2006 and February 2007 (spring-summer). The city was divided into three areas (north, center, and south) and households were randomly selected. Two ovitraps were placed outdoors in the selected houses. Ovitraps were replaced every four hours, from morning (8 a.m.) to late afternoon (8 p.m.). The largest number of eggs was recorded between 4 p.m. and 8 p.m. (81%). These fi ndings enhance our understanding of the vector and thus its control such as spraying during the hours of peak oviposition activity.

“…aegypti seasonal abundance was revised. The characterisation of this seasonal abundance was based on different measures of adult activity detected by ovitraps: proportion of positive ovitraps per time period [Buenos Aires ( Vezzani et al 2004 )], number of eggs per period [Córdoba ( Domínguez et al 2000 ), Tartagal ( Micieli & Campos 2003 ), Resistencia ( Stein et al 2005) , La Plata ( Micieli et al 2006) , Orán ( Estallo et al. 2011) , Santa Rosa ( Breser et al 2013) ], and mosquito detection/non detection per period [Neuquén ( Grech et al 2012) ].…”
