Living With Varroa Mite

Modern beekeeping developed in the absence of Varroa Mite, a parasite of honey bees that invaded North America in the late 20th century. Varroa mites are widespread and are an important factor in loss of bee colonies. The parasites feed on the fluids of larvae, pupae and adults, weakening the bees and are vectors for viruses and other pathogens. Clustering of hives, as is the modern practice, facilitates the spread of Varroa mites among hives. Suppressing swarming allows mite populations to increase. In the wild, mite free swarms of bees can establish new colonies that can stay mite free in isolation of other honey bee colonies. Moving bees from around North America to a single region in California for almond pollination can facilitate spread of both mites and disease across the continent. These practices are all problematic for the maintenance of colony health. Preventing colony loss will not be easy if practices to maintain colony health are not economical. A new model needs to evolve.
