A population genetic analysis was conducted on 47 Aedes aegypti collections from Cambodia. Genetic differentiation at seven polymorphic isoenzyme loci was analysed by starch gel electrophoresis. Low (F(ST)=0.024) but significant (P<10(-6)) differentiation was found when all samples were considered. Whatever the grouping of samples tested, differentiation remained significant but low. The role of human activities (ie insecticide treatments or water storage practices) and environmental factors (ie rainfall) in shaping mosquito differentiation are discussed.
