Honeybee Aggression Linked to Decline in Bumblebee Populations

Researchers at Anglia Ruskin University in Cambridge, England, found that honeybees frequently use aggressive behavior to displace other pollinators from flowers. Their study, published in Ecological Entomology, observed honeybees shoving and chasing rival insects near hives.

Over two years, the team monitored insects feeding on bramble and ivy at five locations within 300 meters of honeybee colonies. They recorded 93 hours of observations focusing on "interference competition," where one insect directly prevents another from accessing food. The study noted that other pollinators avoided honeybees in up to 36% of encounters, and this aggressive behavior is linked to a 14% decline in bumblebee populations.
