Recent Research on Varroa Destructor

Greg Butler did an awesome job sharing the latest research on Varroa mites. It was once thought that the greatest damage to the honey bee was within the cell during the larval stage of the developing bee, particularly in drone cells. It is now known that the greatest damage is done to the adult bee as findings strongly suggest that Varroa are exploiting the fat body as their primary source of sustenance: a tissue integral to proper immune function, pesticide detoxification, overwinter survival, and several other essential processes in healthy bees. These findings underscore a need to revisit our understanding of this parasite and its impacts, both direct and indirect, on honey bee health.
