Dimorfismo sexual alar en Aedes (Stegomyia) aegypti (Diptera: Culicidae) de venezuela

Abstract:

The spread of dengue (DENV) is linked with the presence of Aedes aegypti (Linnaeus, 1762), management and prevention of DENV depend mainly on the control of mosquito vectors. Only the females have blood-sucking habits and vectorial capacity for spread virus, therefore, the discrimination between males and females is especially important in eco-epidemiological studies. Recently, wing shape has been used to describe sexual dimorphism in insects of medical importance using geometric morphometrics. In this study was used 80 wing structures (males, n= 40 females, n= 40) as a morphologic marker to determine sexual dimorphism in Ae. aegypti. Configurations coordinates (x, y) were recorded from 19 Landmarks and lined by a Generalised Procrustes analysis. Discriminant analysis (AD) was performed to test differences in wing shape of each individual group (male or female), and Kruskal-Wallis test to determine differences in the isometric size (CS) according
