SummaryThe beekeepers of Luxembourg were asked for: 1. the honey bee (Apis mellifera) colony losses they experienced over winter; and 2. aspects their beekeeping practice in May 2011 2012. Results on magnitude winter managed colonies are reported for first time, some factors potentially related to such as varroa control methods, agricultural land use at level municipalities hive types employed investigated. The number lost was 938 out 5,580 2010/11 1,172 5,382 2011/12, corresponding national...
Abstract Honeybees (Apis mellifera L.) have an extreme polyandrous mating system. Worker offspring of 19 naturally mated queens was genotyped with DNA microsatellites, to estimate male reproductive success 16 drone producing colonies. This allowed for estimating the on both colony level and individual drones. The experiment conducted in a closed population isolated island exclude interferences drones from unknown Although all colonies had produced similar numbers drones, differences among...
Abstract Twenty managed honey bee colonies, split between 5 apiaries with 4 hives each, were monitored the summer of 2011 and spring 2013. Living bees sampled in July 2011, 2012, August 2012. Twenty-five, medium-aged bees, free varroa mites, pooled per colony date, to form one sample. Unlike France Belgium, Chronic Bee Paralysis Virus (CBPV) has not been found Luxembourg. Slow (SBPV) Israeli Acute (IAPV) levels below detection limits. Traces Kashmir (KBV) amplified. Black Queen Cell (BQCV),...
Abstract Co-evolution between parasites and their host can lead to dramatic changes in the life history of species. In this study we tested male mating success 31 honeybee (Apis mellifera) colonies infested with brood parasitic mite Varroa destructor analysed consequences sexual reproduction on colony survival a closed population Mediterranean island. We found that which successfully reproduced via males had significantly increased mortality during following season. They also showed higher...
