Bee wintering management
The wintering period is the period of high death of bees. In addition, Zhejiang has more rain and fog this year. The death of bees is more serious than in previous years. Recently, there have been bee deaths throughout the country, and the province has also received Cixi and Tonglu counties one after another. Shangri-La City, Shaoxing City, Jiande City and other places reflect the deaths of bees. Most bee deaths occurred in November-December, and a few died from the beginning of October. Most of the death bees were accompanied by bee-sweeping, kissing, and spreading wings. . There are many causes that cause bee deaths, such as bee viruses, bee stings, and spore-worm diseases. At present, the specific causes of death of bees are not clear, and there are no specific medicines. Indiscriminate use of drugs can easily affect the quality and safety of bee products. Therefore, all beekeepers should attach great importance to strengthening the management of the bees during the wintering period and focus on the following aspects: The first is to strengthen the bee farm disinfection. For bee farms where the bees have died, the dead bees should be cleaned up promptly and harmlessly treated (burned or buried). At the same time, beekeeping sites, beehives, nest spleen, and beeware should be thoroughly disinfected. The beehive bees can be cleaned and disinfected with 1%-2% sodium hypochlorite solution or 1%-3% caustic soda solution. Nested spleen can be disinfected with 4% formalin solution. The beekeeping site can be sprayed with 1% bleach solution and 10%. -20% lime water disinfection. The bees where no bees have died are also required to disinfect the beekeeping site. The second is the timely management of bee stings. When the bee colony is damaged, the disease resistance of the bee will decrease, making the bee more susceptible to other pathogens (such as viruses, bacteria, sporozoites, etc.). Therefore, regardless of beekeeping deaths in beehives, the disease should be completely cured, especially during the overwintering period, and during periods of spring propagation and spring propagation. The third is early spring work of bee. The death of bees during the wintering period has been observed in previous years. According to a survey conducted last year, early spring propagation can effectively reduce the death of bees. Therefore, it is recommended that the bees who died from bees be bred in advance. The fourth is to provide high-quality winter feed. In the onset season, it is necessary to ensure that the bee colony feed is sufficient. For bee colonies with insufficient feed, it is necessary to provide subsidies for feeding. When feeding on subsidies, it is best to use high-quality honey spleen, and protein feed is best to use bee pollen.
