Abstract

welve colonies of Apis cerana F. from four different sites (Forestry, UPLB; Bucal, Calambal Banca-banca Victoria; Majayjay, Laguna) were examined by starch gel electrophoresis at the esterase (Est) loci. Esterase was polymorphic in all populations. The main zone of enzymatic activity exhibited bands that varied in mobility. The phenotypes observed were EstS, EstM, EstF. The variants were controlled by three alleles at the same loci for the slow, intermediate and fast forms respectively. The gene frequencies of the populations were EstS 0.65, EstM 0.09, EstF 0.25 (population 1), EstS 0.50 EstM 0.20, EstF 0.30 (population 2), EstS 0.64, EstM 0.07, EstF 0.28 (population 3), EstS 0.53, EstM 0.07,EstF 0.36 (population 4). Genetic identity (I) and genetic distance (D) were estimated. I values range from 0.9678 - 1.00, while the genetic distances between population range from 0.0770 - 0.9835 indicating homogeneity of the different populations.
