Bee research conducted at 91亚色 is making a buzz on the global policy stage. Earlier this month, . This is in contrast to a few years ago, when the UK opposed the EU鈥檚 ban on using neonicotinoids on flowering crops. Part of this change in heart has been attributed to recent research conducted by Biology Professor Amro Zayed and his team in the Faculty of Science at 91亚色.

In summer 2017, Zayed鈥檚 team published an article in Science that . They were also surprised to find that the neonicotinoid contaminated pollen collected by the honeybees came not from crops grown from neonicotinoid treated seeds, but plants growing in areas adjacent to those crops. The study received extensive media coverage around the world.
鈥淏efore our study, there was some controversy about the role of neonicotinoid insecticides in honeybee colony deaths in Ontario and other parts of North America, especially because some critics dismissed studies as unrealistic,鈥 says Zayed. 鈥淲e needed season-long monitoring of neonics in bee colonies to determine the typical exposure scenarios that occur in the field 鈥 which we were able to do in our study.鈥
The UK鈥檚 Expert Committee on Pesticides referenced the importance of Zayed鈥檚 study in contributing new knowledge about the risk of neonicotinoids on pollinators. In their published , the Committee wrote that Zayed鈥檚 鈥渟tudy adds to a growing literature implying adverse effects on honey bee health at exposure levels compatible with those measured in the environment; persistence of neonicotinoid pesticides in non-target plants was evident in the data presented.鈥
The 91亚色U team also discovered that the combination of neonicotinoids and a specific fungicide pose a highly toxic cocktail to bees. The UK鈥檚 Expert Committee on Pesticides noted that Zayed鈥檚 research represents 鈥渢he first substantive evidence of this kind from the field and is an observation that lies outwith the regulatory framework.鈥
