Tropilaelaps: What Beekeepers Need to Know

Tropilaelaps mites are native to Asia and naturally parasitize the brood of the Giant honey bees of Asia. Two species of Tropilaelaps mites are also able to parasitize European honey bees (Apis mellifera). These mites are external parasitic mites that feed on the blood of drone and worker bee pupae, as well as reproduce on honey bee brood. A Tropilaelaps mite infestation causes severe damage to honey bee colonies such as deformed pupae and adults (stunting, damaged wings/legs/abdomens), parasitic mite syndrome, and colony decline. While Tropilaelaps have not yet been found in North America, there is a great deal of concern that if they find their way here it could have a devastating impact on honey bee colonies. This webinar features Dr. Samuel Ramsey, Assistant professor of Entomology at the University of Colorado Boulder, discussing what beekeepers should know about Tropilaelaps. Michigan State University Extension is a steering committee member of the Honey Bee Health Coalition and added closed captioning to the webinar recording.
