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

Bee health research advanced by discovery of parasite-free colony

From Farm Futures

An international team of researchers has discovered honey bee colonies in Newfoundland, Canada, that are free of the invasive parasites – like the Varroa mite – that affect honey bees elsewhere in the world.

The populations allow the researchers to investigate honey bee health, both with and without interfering interactions from parasites.
