New Formula of Pollen Supplemental Diets to Study Honey Bee (Apis mellifera carnica) Attractiveness

Abstract

The present work aimed to examine the attractiveness of ten new pollen supplemental diets to honey bees (Apis mellifera) through evaluating the consumption rate, besides their efficiency in supporting the colony through measuring colony growth (sealed workers brood area). Twelve materials were used and mixed with honey bee in different proportions forming diets taking numbers from 1 to 10. These materials were flours of: gram seeds, beans seeds, pea seeds, fenugreek seeds, coriander seeds, cumin seeds, anise seeds, white kidney beans seeds, caraway seeds, rice seeds, fennel seeds and oats. Diets were consumed at rates that were comparable to the control (sugar candy). Generally differences among consumption rates of supplemental pollen diets were highly significant. The highest consumed amounts were recorded in colonies fed on diet (1); 47.42gm/ colony in average, mix. (2); 43.35 gm/ colony in each week. While the lowest consumption rate (27.3 gm/ colony) in each week was recorded for diet no. 10 in average. There was a significant relationship between the amount of diet consumed and the increase in workers sealed brood area. Where colonies fed with mixture diets from gram seeds (Diet 2), dried pea with rice, fennel and fenugreek (Diet 3), dried beans seeds with fennel seeds (Diet 4) and oats, rice, anise seeds (Diet 1), showed 53.71%, 38.44%, 35.98% and 5.85% more brood area than control ones.
