New findings on Varroa Destructor have turned research into their treatment on its head. The varroa destructor mite is the greatest single problem for honeybees (and beekeepers) worldwide. Scientists have now challenged what we thought we knew.
It turns out for the last 50 years we have been wrong about the Varroa Destructor!
The varroa mite was thought to feed on hemolymph (bees blood). New studies show that they feed on bee fat body tissue instead, causing damage more directly. This finding will necessitate a change in the direction of efforts to control this insect.
