Effects of Different Nutrition Levels of Persimmon Sap on Laying the Queen Bee Colonies of Apis mellifera
Whatever a hive with high population inter a season of collecting nectar the rate of produce honey will increase as well. To provide energy needs in times of nectar shortage in nature, artificial nectar should be used to replace natural nectar, In order to assess the effects of different levels of nutrition, persimmon sap used as a stimulatory nutrition on laying queen bee rate in the colony in spring 2011, This experiment were conducted based on Completely Randomized Block Design (CRBD) with 5 treatments and 5 replications in wild land in Guilan province on (Apis mellifera). To reduce genetic disorders sister queen with the same age were used. Treatments 1, 2, 3, 4, and 5 were sugar and water syrup 1:1; persimmon sap and water, 3:1; persimmon sap and sugar, 1:2; persimmon sap and white sugar, 1:1 and persimmon sap and sugar, 2:1, respectively. Treatments were used for 60 days. Amount of laying by queen was measured by determined scale. Related data to influence of nutrition on laying of queen showed that there was a significant difference between control treatment and experimental treatment (p<0.05). The most amount of laying was belong to treatment 4 and the least amount was observed in treatment 2.
