According to a new study, humans are to blame for the killing of honeybees.
Researchers found that human practices are the cause for the recent decrease in honeybee population. The study revealed that honeybees are killed by a viral disease unintentionally spread by humans.
Scientists declared that the virus that exists among honeybees is called Deformed Wing Virus. They also found that human trade and transportation of bees caused the propagation of the virus which is now leading to the death of honeybees.
Dr. Lena Wilfert, the lead author of the study, announced that they found proof that human activities have had a major part in the epidemic. She also added that there would have been evidence of conveyance between countries close to each other if the propagation of the virus was naturally caused. Their data showed that virus populations affecting honeybees from New Zealand came from Europe.
This supports the theory that man’s transportation of bees causes the spread of this disease. The researchers analyzed virus samples taken from bees around the world in order to see how it spread. The results showed that the virus traveled from Europe to North America, Australia and New Zealand.
They didn’t find any movement between Asia and Australia. However, they did find evidence of transportation between Europe and Asia. In addition, scientists investigated other species of bees and revealed that the main cause of the virus’s spread was the European honeybee.
Dr. Wilfert said that:
”We must now maintain strict limits on the movement of bees, whether they are known to carry Varroa or not. It’s also really important that beekeepers at all levels take steps to control Varroa in their hives, as this viral disease can also affect wild pollinators.”
Researchers’ main concern is that the deaths of honeybees may have a massive impact on biodiversity as well as human health. Honeybee colonies play an important role in agriculture systems but their transportation around the world has a very high risk. Scientists claim that there will be huge consequences not only for domestic animals but also for wildlife.
The study shows that humans are to blame for the killing of honeybees. However, it wasn’t on purpose. We trade and carry honeybees from one place to another in order to get better hives or honey for more and better pollination to take place.
Scientists still try to find a solution in order to solve this problem. More details of this study are found in the journal Science.
