摘要：

Allozymic variability was analyzed for 8 samples of the floodwater mosquito Aedes albifasciatus (Macquart) obtained in October and November 1993 from marsh and pasture habitats along the Mar Chiquita ecosystem in central Argentina. Expected mean heterozygosity among 17 loci was low. F-IS values were negative for all polymorphic loci, and mean F-ST values were low, indicating high levels of gene exchange and the absence of subpopulations within the 25-km-wide study area. Genetic homogeneity throughout the area suggests that outcrossing occurs frequently as a result of dispersal among sampled sites.
