Honeybee mite raises the risk of bee virus. Yours sincerely: Sophie Hedges
The bloody virus, which spreads a dangerous virus among bees, also plays an indirect role in the infestation of wild bees, new research shows.
The Varroa destructor cell lives in bees and can spread a deformed wing virus (DWV) through the hive. of the last century. Since then, it has spread worldwide through the human-induced movement of infected honey bees and has become a viral vector.
Researchers say their findings highlight the need for beekeepers to treat bee colonies affected by mites to protect wild bees.
"We compared areas where bees had Varroa destructor mites with tickless areas," said Dr. Robin Manley of the Center for Ecology and Conservation at Exeter University, Penryn Campus, in Cornwall, who found higher levels of the virus in the wild bees and the infected bees share their environment with the bees who feed on the same flowers and carry the virus
A large number of bees in the UK and many other countries live in hives kept by beekeepers, Dr. Manley said the study has raised an important point for them. "Some beekeepers prefer not to "There is a global epidemic of DWV, partly caused by the spread of the Varroa destructor mite," said Professor Wilfert of the University of Ulm , Germany
the virus seriously affects colonies of bees, there are fewer studies on the impact on wild bees, but previous studies have shown that they can reduce their lives. bees and wild bee populations.
There are different strains of DWV, and the Exeter study supports the view that DWV-B assumes the most prevalent DWV-A strain. DWV-B is known to be more harmful to honeybees, but it is still unclear whether and how strains affect wild bees differently
