title: Isozymes of Culex p. fatigans. I. An esterase locus in linkage group III and its variability in natural populations.
abstract: Acrylamide gel electrophoresis revealed 19 frequent and 4 rare sites of esterase activity in various Brazilian populations of Culex p. fatigans. One pair of allozymes designated as Est-1 F and Est-1 S was selected for detailed investigation. Est-1 locus shows independent assortment from linkage group I marker, sex, and linkage group II markers, yellow and ruby, and therefore is assigned to linkage group III. Gene frequencies of Est-1 F varied from 0.49 to 0.92 in various Brazilian populations. Inhibition studies suggest that Est-1 F and Est-1 S are ali-esterases.
