Abstract
The isozyme and morphological variability in natural populations of the Asian honey bee (Apis cerana Fabricius) from three different geographical areas in the Philippines (Area I: Batangas, Cavite, and Laguna; Area II: Cagayan de Oro; Area III: Bicol) were detected by starch-gel electrophoresis and morphometric analysis. Isozyme polymorphisms were detected for alkaline phosphatase, acid phosphatase, esterase and malate dehydrogenase, as encoded by 13 presumptive loci. Based on the observed proportion of polymorphic loci and average heterozygosity, genetic variability was highest in the Area II population. The genetic and genotypic variabilities between populations from Areas I and III suggest a possible mechanism of subspeciation. Principal component analysis of 31 morphometric characters yielded 4 possible clusters of bee populations. Areas II and III each formed distinct clusters, but Area I was divided into the Batangas-Cavite cluster and the Laguna cluster. The Cagayan de Oro (Area II) population had the highest measurements for most of the size-related characters, whereas the Bicol (Area III) population had the lowest. The isozyme and morphometric analyses of Apis cerana consistently showed considerable divergence between the populations from Areas I and III. However, The Area II population was not as distict from the other populations.
