Stronger pesticide regulations likely needed to protect all bee species, say studies

Pesticide regulations designed to protect honeybees fail to account for potential health threats posed by agrochemicals to the full diversity of bee species that are even more important pollinators of food crops and other plants, say three new international papers co-authored by University of Guelph biologists.

As the global human population grows, and as pollinators continue to suffer declines caused by everything from habitat loss to pathogens, regulators need to widen pesticide risk assessments to protect not just honeybees but other species from bumblebees to solitary bees, said environmental sciences professor Nigel Raine, holder of the Rebanks Family Chair in Pollinator Conservation.

“There is evidence that our dependency on insect-pollinated crops is increasing and will continue to do so as the global population rises,” said Raine, co-author of all three papers recently published in the journal Environmental Entomology. MORE
