Abstract

Pollen pellets for the Asian honey bee. Apis cerana F. and the Italian honey bee. Apis mellifera L. during the peek pollen season from several areas of the country were analyzed and compared. Pollen types were identified and their frequency of occurrence in the samples were determined.

Twenty pollen species from seventeen families were identified from fourteen sites. Of these, Mimosa pudica L. Cocos nucifera L. Ageratum sp. Acacia sp.. Myrtaceae and Aeachynomene sp. were identified as important pollen types. Leucaena leucocephala (Lam) de Witt.. Muntingis calabura L. species from compositae. Tilliaceae. and Moraceae were the secondary pollen sources. Seven types were identified as important minor pollen sources and nine types were minor sources.

Dendrogram analysis of the data revealed the presence of three main clusters and four isolated areas. The first cluster is characterized by the predominance of Mimosa pudica L. The second cluster is predominated by Mimosa L. and Cocos nucifera L. The third cluster is characterized by the presence of Ageratum sp. as the predominant pollen type.

Similarity indices were computed for the Apis cerana F. and Apis millifera L. samples in all areas. Pollen foraged by both types of bes had the least similarity in Benguet indicating low competition in the area: and the highest similarity in Tagaytay indicating high competition in the pollen foraged by both bees in this area.
