ABSTRACT
Eighteen enzymatic loci were analysed in Aedes aegypti populations from four neighbourhoods in the city of Manaus. The analyses showed that the Downtown population was the most polymorphic (p = 55.6 percent) with higher observed and expected mean heterozygosities (Ho = 0.152 ± 0.052; He = 0.174 ± 0.052, respectively). The least variability was detected in the Coroado and Cidade Nova populations, both with polymorphism of 44.4 percent. The latter population presented the least observed heterozygosity (Ho = 0.109 ± 0.037). Wright's F statistics showed that the mean value of Fis was higher than that of Fst (Fis = 0.164 > Fst = 0.048), and from analysis of molecular variance (AMOVA) it was found that 95.12 percent of the variability is found within populations indicating a certain intra-population differentiation possibly of the microgeographic structure resulting from some barrier in the random coupling. Although the four populations were similar genetically (D = 0.003 to 0.016), the 4.88 percent differentiation was significant
