Abstract

Cytological and other genetic differences among European honey bee (Apis mellifera L.) populations reared in agricultural (Calauan), forested (Forestry, Los Baños), and industrial (Canlubang) areas of Laguna determined by hemocyte and isozyme analyses. The diversity among bee samples was assessed before and after transport as the control and experimental groups, respectively. The total hemocyte counts before and after transport were not significantly different among managed honey bee colonies from the tree areas, but significant differences were noted in the unmanaged colonies at six months after transport. The differential hemocyte counts in the control populations (before transport) were significantly different from the experimental group (after transport). The number of prohemocytes were notably increased after transport, especially in the unmanaged colonies from Canlubang. Isozyme analyses revealed that alkaline phosphatase, acid phosphatase, and malic enzyme were all polymorphic among honey bees from all sampled areas. The observed values for genetic distance suggested that all populations remained genetically similar despite the environmental variation caused by colony transport and the use of different rearing practices.
