Eggs laying activity of honeybee queens,raised in bee hive types:12 frame Dadan Blatt (DB-12), hive 10 frame Dadan Blatt (DB-10), hive Langstrot Ruth (LR), Roger Delon (RD) and Farrar was estimated. Bee colonies reared in LR hives, had the highest egg laying rate, followed by those reared in DB-12 hives and DB-10 hives respectively. The bee colonies reared in RD and Farrar hives had the lowest rate of egg laying. Eggs laying dynamics had 2 pronounced peaks. The first peak was observed in mid – June, while the second one was observed following the end of the main foraging season and was probably due by supplemental feeding of sugar to the bee colonies.
