CIReine - Conception d’Indicateurs de qualité des Reines d’abeilles

Abstract : The objectives of this project were to develop early and non-invasive indicators for queen’s quality. In the same time, it proceeded (1) to the development of an electronic device to record the activity of queens inside the hive and to (2) test the relevance of different simple indicators (weight, colony dynamics) in connection with the performance of the colonies. It also contributed (3) to the development of sets of genomic markers to ensure the quality of queen mating with drones. This work began with the evaluation of the glues used for marking bee queens by beekeepers. The results of this study guide beekeepers towards less harmful glues for their bees. Then various experiments, gradually, allowed developing a system to automatic record the position of a queen inside her colony thanks to a RFID technology. This very innovative system has resulted in the creation of six devices that are thus available to apidologist researchers for their future research on the behavior of bees. Experiments that have made it possible to finalize the device already bring some useful knowledge, the absence of differences between daytime and nocturnal activity for example. It turns out, however, that the activity of a queen within her colony is relatively little related to the dynamics of it. The follow-up of nearly 300 queens throughout the project made it possible to study and disseminate knowledge on the impact of the dynamics of a colony, linked to the queen spawning, on all beekeeping performances. The link between colony dynamics and dynamics of Varroa infestations has been studied in detail and raised the importance of monitoring infestations on highly populated colonies in season, which, if they appear ideal for producing honey, are also subject to very strong varroas infestations. Unfortunately, simple and easily accessible criteria for beekeepers, such as the weight of queens, remained too unreliable to predict the quality of queens. The search for genetic markers to know the origin of the males which fertilized the queens should soon lead to a product available to beekeepers. It will allow breeders and conservatories to ensure the quality of their fertilization areas.
