Assessment of manipulations in domesticated bee colonies on production and quality of queen bee
Author(s): Neeraj Kumar
Abstract: For development of simpler method of queen raising, studies on manipulations in colony viz., placing dummy board in between & side of the colony and use of double chambers with queen excluder for queen production and quality were carried out at University Apiary, RPCAU, Pusa during autumn season of 2016-17. In the colonies that were placed with dummy board after 5-frame had more number of drone cells and queen cells being 1979.00, 3.00 in Apis mellifera and 538.33, 2.00 in Apis cerana, respectively. The 5-framed colony showed superiority over all the parameters studied except period of emergence to mating than 4-framed colony being number of drone cells 1635.33, 417.67 and queen cells were 2.67,2.00 in both the species respectively. However, the success of queen remained same in both the species whereas the number of eggs laid per day differed widely, 1325.67, 1203.33 in A. mellifera and 896.67, 807.00 in Apis cerana in 5 framed and 4 framed colonies, respectively. When half of the colony was made queen less, the two species showed distinct variations in different parameters The number of drone cells were 1357.67 in Apis mellifera and 479.33 in Apis cerana. The number of queen cells formed were 3.33 in A. mellifera and 2.67 in Apis cerana. The numbers of successful queens were also more (2.0) in Apis mellifera and 1.33 in Apis cerana. The eggs laid per day were also more (1012.67) in Apis mellifera than Apis cerana (757.67). Dummy board proved better when provided in middle of the colony than placed in the side of colony because when half of the colonies were made queenless placing dummy board in middle produced more (3.33,2.67) queen cells in Apis mellifera and Apis cerana, respectively. The performance of queen produced in double brood chambers with queen excluder colony were better having body weight being 179.33-mg and 127.6-mg and eggs laid per day were 1243.33 and 832.67 in Apis mellifera and Apis cerana, respectively.
