UC Riverside Study Shows Managed Bees Spread and Intensify Diseases in Wild Bees

Wild pollinators are in decline across many parts of the world. To combat this, managed honey bees and bumblebees are frequently shipped in to provide valuable pollination services to crops.

But does this practice pose any risk to the wild bees?

An entomologist at the University of California, Riverside led a research team that has examined the evidence by analyzing the large body of research done in this area to come to the conclusion that managed bees are spreading diseases to wild bees.

“Even in cases when the managed bees do not have a disease, they still stress local wild bees, making them more susceptible to disease,” says Peter Graystock, a postdoctoral researcher in the Department of Entomology and the lead author of the study.

Many countries have inadequate – or no – laws for bee movements. The globalized trade in bees has enabled almost free movement of diseases around the world.
