Researchers in Pennsylvania believe that they have discovered a combination of impact factors that have caused the death of bee populations, including the suppression of the bees' immune system by bees. The researchers published their findings on the online version of Proceedings of the National Academy of Science on May 17th. The crab bee is called a bee sting, commonly known as a bee sting, and it is a kind of parasite on the bee body. This kind of cockroach is only dark and brown with a needle. This bee sting may have originated from oriental or Chinese bee populations and spread to the United States in 1987. One of the symptoms of bees being infected by this mite is that the wings have become deformed. Sometimes the seemingly healthy bee colonies are sick and the entire hive collapses within two weeks. Native Chinese honeybees did not suffer from these problems because they had some dressing practices that could drive out the mussels. Although the researchers knew that this kind of beggar was the cause behind the death of the bee population, the mechanism leading to death was still unclear. Now, Yang and Diana L. Cox-Foster believe that bee stings, ornithitis virus, and bacteria cause the death of colonies. Once a cockroach begins to bite a developing bee, all later cockroaches will use the same food intake. Other researchers have demonstrated that harmful and harmless bacteria can infect this feeding site. Distortion wing virus is a kind of endemic disease in bees in the United States. But a separate orphaned wing virus can neither cause the wings to deform after the bees come out of the cocoon, nor can it cause the group to die. The combination of bee sting and infestation with the winged virus can indeed cause about a quarter of the newborn bees to appear distorted, but it cannot cause a sudden collapse of the beehive. This means that there are other factors associated with causing bee stings to be so harmful to swarms. Yang and Cox-Foster analyzed the effects of bee stings on the bees' immune system. They injected heat-killed E.coli into bees that were infected with the virus (breeding bee sting or no sting). This dead bacterium was used to trigger an immune response (similar to a human vaccine) for bees. They examined the ability of honeybees to make honey-disinfecting compounds (glucose oxidase, GOX) and other immune-related compounds. The researchers also measured the amount of virus in each bee. They were surprised to find that when the bees came in contact with bacteria, the virus in the breeding bee rapidly increased to very high levels. The level of virus in bee-free bees did not change when the bees injected bacteria. This tick also suppresses other immune reactions in the bees, making the bees and colonies more susceptible to infection. Bee stings can infect larvae from adult bees. This virus can also be transmitted through many different routes.
