The relationships between produced drone honey bee brood and certain meteorological factors (mean daily temperature, mean daily relative humidity, sunshine hours and wind velocity), honey bee colony activities during natural growth period, and the effect of the four meteorological factors on drone flight activity and their relation to pre-oviposition period of queens during natural mating periods were studied from 1 January to 31 May 2003 in Egypt. The drone honey bee brood area was maximum on 7 March, and minimum at the end of May. Positive correlations were found between produced drone honey bee brood and both bee population and produced worker brood. Correlations were negative between drone honey bee brood and each of stored pollen, uncapped honey and capped honey. Drone honey bee brood area was negatively correlated with daily temperature, but positively correlated with daily relative humidity. All above-mentioned factors affected drone honey bee brood production by 85%. Significant differences in drone flight activity were found among most day-hours. The number of flight drones during the whole natural mating period was maximum at 14.00 h, and minimum at 11.00 h. Drone honey bee flight activity was positively correlated with both daily relative humidity and sunshine hours, but was negatively correlated with both daily temperature and wind velocity. These factors affected drone honey bee flight activity by 31.5%. Pre-oviposition period was shortest on 1 April, and longest on 1 May, indicating that April can be considered the best time for queen mating.
