A dangerous variant of the deformed wing virus is on the rise worldwide. The virus infects honeybees, causing their wings to atrophy and the animals to die. The new variant, which has already replaced the original strain of the virus in Europe, is spreading to other regions of the world and causing entire bee colonies to collapse. This has been shown in a study by an international research team led by Martin Luther University Halle-Wittenberg (MLU), which analyzed data on the spread of virus variants over the past 20 years. The paper appeared in the International Journal for Parasitology: Parasites and Wildlife.
