If young bees have deformed wings and larval bees die in the cells before hatching, one thing is certain: The honey bee colony is in great danger. Varroa mites and Varroa-transmitted viruses are usually the cause of this disaster. A study in the German Main-Kinzig district, carried out by the Frankfurt University Bee Research Institute, shows how this parasite can be efficiently kept in check.
// The Varroa mite is one of the biggest challenges beekeepers face in Europe and North America.
// Beekeepers participating in a five-year-long field study, only had overwintering losses of less than 10 percent
// To prevent resistance mechanisms, beekeepers need to alternate active components.
The eight-legged Varroa mite is only 1.6 mm in size but looks threatening under the electron microscope.
