IMPACT OF NATURAL AND SUPPLEMENTARY FOODS ON CERTAIN PHYSIOLOGICAL AND PRODUCTIVITY CHARACTERS OF HONEYBEE COLONIES

Abstract

The present study was carried out in the apiary of Plant Protection Research Institute at El-Quanater, Qaluobia Governorate, over the course of three years, 2019, 2020 and 2021. 5.1. The activity of collecting pollen in the study area during four seasons (autumn, winter, spring and summer) in the year 2019/2020 Four random colonies of the apiary colonies were used, and the pollen-collecting trap was installed on each colony, where the traps were installed one week and raised the next week as an indicator of the period of abundance and scarcity of pollen grains in the study area, and the results were as follows: 5.1.1. In the autumn season: The obtained results indicated that the amount of bee pollen collected during autumn season, started on the first of October until the middle of December, in the weeks of collection were 16.62, 31.87, 37.54, 16.55, 17.41 and 15.61 (gm/ week) in the first, second, third, fourth, fifth and sixth week, respectively with an average of 22.60 g/ colony/week. 5.1.2. In the winter season: Results clarified that the largest amount of pollen collected during the winter season was in the last week of March 7-14 was 55.39 g with a significant difference between it and the weeks preceding it, followed by the fourth week, followed by the fifth, then the third, and the least of them was the first week. The quantities were (46.51, 35.86, 31.47, 14.52, 8.57 g), respectively with an average of 32.05 g/ colony/week.
