Abstract

The pollen content, and some physico-chemical characteristics of honeys from Trigona sp., Apis cerana F. and Apis inellifera L. were compared. Honey samples were obtained from hived colonies in Magcasile, Guinobatan, Albay. Cocos sp. (75.56%) and Mimosa sp. (24.63%) were the primary pollen sources of the three bee species. Secondary pollen source were Cycas sp. (0.06%) for Trigona sp , Rutaceae (0.07%) and Leguminoceae (1.7%) for Apis mellifera. There was an overlap in the pollen preferences of the three bee species. The acidity ( pH ) varied . The most acidic honey was from Trigona sp. (3.3), followed by Apis cerana (3.8) and Apis mellifera (4.1). The conductivity (mV) of honeys from A. cerana, A. mellifera and Trigona sp. was 5.4, 5.6 and 5.7 respectively. The moisture content in A. cerana (40.6%) , A. mellifera (35%) and Trigona honeys did not conform with the international standard, which is 18%. The reducing sugar of Trigona honey ( 48.3 g/100g honey) was below the standard set by the International Commission for Bee Botany (1982). The amount in A. cerana and A. mellifera honeys were 66.6 g / 100 g honey and 62.1 g/100g honey respectively. The apparent sucrose content of all the honey samples were minimal compared with the standard (55g/100g honey).
