Not a Pretty Sight

Oct 9, 2009

It's not a pretty sight--the Varroa mite attacking a honey bee.

Beekeepers are accustomed to seeing the reddish-brown, eight-legged parasite (aka "blood sucker") in their hives.

UC Davis bee breeder-geneticist Susan Cobey, manager of the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, is among those who've declared war on the mites.

She's carrying out an intensive and comprehensive breeding and selection program aimed at developing honey bees that are resistant to pests and diseases.

The Varroa mite is a serious pest of honey bees worldwide, spreads diseases,  and can weaken and destroy the colony. It is no doubt one of the culprits involved in colony collapse disorder, a mysterious phenomenon characterized by honey bees abandoning the hive.

Here's what the Varroa mite looks like attacking an immature bee.
