Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers at Penn State who analyzed seasonal trends of parasite and virus transmission in bees. The study — published in the journal Ecosphere — found that honey bees consistently had higher levels of viruses than bumble bees. Additionally, while both types of bees had lower virus prevalence in the winter, only bumble bees experienced negligible levels by spring.

Winters can be tough on managed honey bee colonies, with beekeepers in the United States reporting that one-third of their colonies die each winter. A new study by Penn State researchers has found that using not one but multiple pest treatments may be important for helping bees make it to spring. The researchers found that beekeepers who used a combination of treatments for Varroa mites — tiny parasites that can weaken and spread diseases to honey bees — had higher winter colony survival than those who used only one type of treatment, acc...
