Pesticides damage survival of bee colonies, landmark study shows

The world's largest ever field trial demonstrates widely used insecticides harm both honeybees and wild bees, increasing calls for a ban

Widely used insecticides damage the survival of honeybee colonies, the world's largest ever field trial has shown for the first time, as well as harming wild bees.

The farm-based research, along with a second new study, also suggests widespread contamination of entire landscapes and a toxic "cocktail effect" from multiple pesticides.
