Populations of Anopheles triannulatus from Macapá (AP), Aripuanã (MT), Ji-Paraná (RO), and Manaus-Janauari Lake (AM) were studied using 16 enzymatic loci. The results of the isozyme analysis showed that the population of Macapá presented higher polymorphism (56.3%). The lowest variability was observed in the population of Manaus (p = 25.0; Ho = 0.077 +/- 0.046). The results of Wright's F statistics showed unbal...
Four populations of Aedes aegypti from Manaus were studied, using allozymes and RAPD loci, to determine intra- and interpopulation genetic variability and differentiation and to compare genetic structure parameters assessed with both markers. Five RAPD primers produced 52 polymorphic fragments, whereas only seven of 18 isozyme loci were polymorphic. The population from Praça 14 was the most polymorphic (P= 94.2...
Our group analyzed species of Anopheles of the subgenus Nyssorhynchus (An. darlingi, An. marajoara, An. oswaldoi, An. benarrochi, An. triannulatus and An. rangeli) and a single species of the subgenus Anopheles (An. mattogrossensis), originating in the Amazon, based on the mitochondrial DNA control region. The fragment had 381 pb and the nucleotide composition in A+T ranged from 85.8 to 89.5%. DNA polymorphism ...
An isoenzymatic comparative analysis of the variability and genetics differentiation among Anopheles species was done in populations of An. (Nys.) intermedius and An. (Ano.) mattogrossensis of the Anopheles subgenus, and of An. darlingi, An. albitarsis and An. triannulatus of the Nyssorhynchus subgenus, with the aim of detecting differences between both subgenera and of estimating the degree of genetic interesp...
