Varroa destructor mite
The most serious pest of modern beekeeping is Varroa destructor, an Asian mite that jumped from the eastern hive bee Apis cerana to the western bee Apis mellifera when commercial beekeeping brought the two bee species into contact. The mite causes severe winter losses in heavily infected bee yards. Here, a mite rides on the abdomen of a worker bee.
