How to prevent bee cystic larvae?

Cystic larvae disease is caused by cystic larvae virus. The 2-3-year-old larvae are mainly infected, and the incubation period is 5-6 days. The diseased larvae usually die after sealing. The dead larvae have a raised head, white, odorless, and can be easily pulled out of the nest with pliers. The tail has a small sac filled with fluid. After the insects die, the nest lid is dark black, concave and perforated. "Flower arranging seeds" were found on the spleen. Every morning, as the bees begin to collect, the worker bees will be seen pulling the carcasses of the diseased insects out of their nests and scattering them on the ground at the entrance of the hole. From this, a basic diagnosis of the disease can be made. If possible, further electron microscopy and serology can be performed.

Prevention and control should be strengthened, and measures such as disease-resistant breeding, prevention and disinfection of bee tools and feed, and strengthening of bee colony feeding and management should be adopted to reduce the incidence of bee colonies. For bee colonies that have already been sick, the nest can be cleaned with broken seeds and treated with drugs.
