V. destructor on a honeybee host — USDA
❝ It isn’t just pesticides and the destruction of habitat that’s making the world’s honeybees very unhappy. One of the biggest threats is Varroa destructor, a disease-spreading parasite that is just as villainous as its name suggests.
❝ Through a chance discovery, scientists from the University of Hohenheim have stumbled on a new method of wiping out this parasitic pest without harming the bees.
The US Department of Agriculture views the Varroa mite as “the major factor underlying colony loss in the US and other countries.” After infiltrating a colony, the mites begin to feed on the bodily fluids of honeybees and their larvae. Along with weakening the bees, the mites also spread viruses, such as deformed wing virus, and can quickly wipe out entire colonies…
❝ “Lithium chloride can be used to feed bees in sugar water. In our experiments, even small amounts of saline solution were enough to kill the mites sitting on the bees within a few days – without side effects for the bees,” Dr Peter Rosenkranz, head of the German State Institute of Apiculture…
