Caption: Varroa bee mite (Varroa destructor) on a honey bee leg. Varroa mites are external honey bee parasites that attack both the adults and the brood. It attacks two types of honey bees, Apis cerana (Asian honey bee) and Apis mellifera (Western or European honey bee). Until recently this species was misidentified as Varroa jacobsoni. The mites suck the blood (hemolymph) from both the adults and the developing brood, weakening and shortening the life span of the ones on which they feed. Varroa mites reproduce on a 10-day cycle. Emerging brood may be deformed with missing legs or wings. Untreated infestations of varroa mites that are allowed to reproduce will kill honey bee colonies. The infection and subsequent parasitic disease caused by varroa mites is called varroatosis. Treatment has had limited success. The Varroa mite has been the parasite with the most pronounced economic impact on the beekeeping industry. It may be a contributing factor to Colony Collapse Disorder that is threatening hives throughout North America. The varroa mite is considered one of the most serious honey bee pests and occurs almost worldwide. Hawaii had been one of the few places where the mite was not known to occur but in 2007 it was found on Oahu.
