Effect of different seasons on some honey bee activities under Nasr City conditions - (Cairo) Egypt

This study was carried out at the apiary of the Plant Protection Department- Faculty of Agriculture - Al-Azhar University- Cairo during year (2013&2014). Colonies of carniolan F₁ hybrid were used. The results showed that the largest monthly mean of the sealed worker brood area (in.²)/colony recorded (370.0, 369.2 and 292.2) in spring for the colonies without traps (control), with fixed trap three days and without three days (3&3) consequently and colony with fixed traps, along the whole time of the investigation period, respectively. While the smallest monthly means of the sealed worker brood area (in.²)/colony recorded (146.4, 140.9 and 121.3) in autumn for control and another two treatments, resp. Spring season is the best season for the monthly means of the stored pollen area (in.²)/colony (137.3, 111.8 and 88.8) for control , and another two treatments resp. Whereas, the smallest monthly mean of the stored pollen area (in.²)/colony recorded (28.2, 22.2, and 12.6) in autumn for control and another two treatments resp. The spring season is the best, where the monthly means of the stored honey area (in.²)/colony were (600.0, 480.2 and 338.3) for control, and another two treatments, respectively. The smallest monthly means of the stored honey area (in.²)/colony recorded (70.4, 65.0 and 44.6) in autumn for control and another two treatments resp. the other two seasons are ranked in between in the three activities. All data obtained were statistically analyzed and discussed.
