In this presentation, Dr. Samuel Ramsey explains his groundbreaking research revealing that Varroa mites feed on honeybee fat body tissue rather than their blood. He demonstrates that these parasites have been misunderstood for decades due to translation errors from early Russian studies and their hidden feeding locations on the underside of the bee's abdomen. Through forensic microscopy and fluorescent imaging, Ramsey proves that mites consume the fat body, an organ essential for detoxification, immunity, and winter survival. This discovery challenges the long-held belief that mites are merely "hitchhikers" during their phoretic phase, showing they are actually causing continuous damage. Ultimately, Ramsey highlights that visual inspections of a bee's thorax are unreliable for monitoring infestations since most mites remain tucked between abdominal plates. His work suggests that modern beekeeping management must account for the severe physiological toll this specific tissue loss takes on hive health.
