|Abstract:||Producing package bees (adult bees and a young queen) and nuclei (small colonies, each with brood, adult bees and a young queen) is one strategy for establishing new colonies and replacing those that are weak or dead. Although beekeepers around the world commonly engage in this work using various methods, scientific literature on the subject is scarce. In Canada, there is a growing need to replace and increase colony numbers to satisfy the demand for pollination services and compensate for high winter colony mortality. The main objective of our study was to develop a methodology for producing new colonies that is both more structured and better adapted to the challenges facing today’s Canadian beekeeping industry. One package bee and two nuclei-making techniques were compared at the Deschambault Research Center for Animal Sciences in 2014: A) 1 kg of adult bees + young mated queen, B) one brood frame + adult bees covering frames + young mated queen, C) two brood frames + adult bees to covering frames + young mated queen. In total, 38 new colonies were produced. These colonies were monitored from July 2014 to June 2015, measuring a set of parameters designed to evaluate their strength as well as levels of varroa mite infestation and nosema disease infection. Results showed no significant statistical differences in the development of these colonies. However, the findings confirm that technique B) represents the best multiplication potential and that retrieving bees or brood in hives for making nuclei controls both varroa mite infestations and swarming.|
