Scientific research & other resources on neonicotinoids

Much has been written and is available to the reader online on the subject of neonicotinoids and their linkage to bee poisonings. Among these are the following reports and peer-reviewed papers that the OBA believes to be particularly relevant and useful. We will keep this section updated with new information as it appears.
