Biologia de Anofelinos Amazônicos. VI. Variabilidade Enzimática em ANOPHELES DARLINGI Root. (DIPTERA, CULICIDAE)

Abstract

We have, related preliminary results on protein polymorphism in two natural populations of Anopheles darlingi from the Amazon region (Ariquemes, state of Rondonia, and the Highway PA-422, in the state of Para). Fοr the esterases there were observed variations in the locus Est-2in the Ariquemes population, while while locus was onomorphic in the Highway PA-422 population. In the later population we found individuals showing the genotype. Est2*F/Est2*F. The allele frequency Est2*Fhas been estimated at 0,80 in the population of, Ariquemes, this value being much higher than the one related to our previous study on the Highway BR-174 (Manaus/Boa Vista) which was 0,48. The results concerning leucine-aminopeptidases (LAP) suggest that this enzyme is controlled by three apparently monomorphic loci in the both populations.
