Management of honey bee colonies may contribute to Varroa populations, study shows

Close proximity of honey bee colonies may contribute to Varroa population growth and virus transmission, according to an article recently published in Environmental Entomology. Varroa just detach from their current host and hitch a ride to another colony on a visiting foraging bee.

Varroa mites don’t reproduce very fast. A female mite will produce one to three offspring; infestations take several years to reach levels that would threaten the hive. However, in managed honey bee colonies, varroa populations increase rapidly, causing beekeepers to apply up to seven miticide applications per year. Continue reading
