Genetic heterogeneity of the dengue vector Aedes aegypti in Martinique

Trop Med Int Health. 2004 May;9(5):582-7. doi: 10.1111/j.1365-3156.2004.01241.x.

Abstract

In Martinique, Aedes aegypti, the vector of dengue viruses has been the target of insecticide control for more than 35 years. Despite significant control efforts, dengue has become a major disease of public health concern. We conducted a population genetic analysis based on isoenzyme variations combined with an estimation of infection rate to a dengue virus among 26 Ae. aegypti samples. Aedes aegypti samples could be differentiated for their susceptibility to dengue infection (infection rates ranging from 42.8% to 98.6%) and showed important genetic variation (significant F(ST) values).
