Abstract
Genetic variation at 26 loci in a natural population of Anopheles aquasalis has been studied by zymogram technique. Average proportion of polymorphic loci is 23% (criterion I) and 34% (criterion II). On the average 8.1% of the genome is in heterozygous condition in each individual. The degree of genetic variability varies from locus to locus. Some enzymes such as AO, alpha-GPDH, 3 loci of HK, 3 loci of LAP, 3 loci of MDH, GOT, 3 loci of ODH and one locus of EST (EST-4), are monomorphic. Of the rest, proportion of heterozygosity varies from the minimum of 0.041 at Xdh-2 to a maximum of 0.493 at Est-2. Similarly, except for the loci Est-2 and Est-3, proportion of heterozygote individuals is extremely low. A. aquasalis has a higher genetic identity with A. evansae (I = 0.625) than with A. argyritarsis (I = 0.543). There seems to be direct correlation between the genetic variability of a species and its capacity to explore diverse ecological nitches.
