Abstract
     This study was conducted during spring of 2021, (Marsh to May,) to evaluate the suitable diurnal time (early morning (8.00-9.00 am), mid-day (1.00- 2.00 pm) and before sunset (6.00-7.00 pm) and to define the synchronized period (7, 14, 21 days) required to gain high yield of venom from honeybee colonies. The first experiment was conducted to evaluate the diurnal profitable time, to gain the highest yield of dry bee venom. For this purpose, twelve colonies of Carniolan hybrid in similar strength were divided into three equal groups. The results proved that the mean highest amounts of venom collected before sunset was significantly higher (26.9± 1.9 mg/col.) than those collected in either the early morning (17.0± 3.8 mg /col.), or in mid-day (15.0± 2.6 mg/col.). The second experiment targeted suitable synchronized period spent between two successive collections of venom from the same colony. Three tested interval periods were investigated (7, 14 and 21 days, using 24 colonies from the same hybrid in homogenous strength divided to three equal groups. Each group applied in one of the mentioned synchronized periods. The results indicated that collecting venom after 14 days from the first collection gained the highest venom amounts (21.5 ±3.7 mg/col.), with non-significant difference with the 21 days period (20.7± 2.1 mg/col.). However, the collected amounts of venom after 7 days from the first harvesting were significantly less (17.7± 2.2 mg/ col.) than the other periods.
