Abstract

Pollen sources of the wild bee (Apis cerana) In selected areas of the country (Lips, Bay, Calauan, Mudspring, College of Forestry, and Palawan) were determined by collection and analysis of the pollen loads of the wild bees in each site. Twenty five pollen grains were identified, three of which were considered most important pollen sources. The botanical and geographical origin of the pollen grains were determined. The pollen load spectrum of the honey samples were subjected to cluster analysis to determine the degree of similarity among the sites. In terms of pollen spectrum, Palawan collection is the most unique, showing the lowest similarity index to the rest of the sampling sites. Cluster analysis of the monthly collection of honey In College of Forestry (COF) reveals the seasonality of the major pollen plants in COF. Except for Mudspring, all of the honey samples from the remaining sites are unifloral. The pollen density of all the honey samples from the six sites ranges from 20,000 to 100,000 pollen grains per 10 g honey (Class II).
