When I began writing this website in 2009/2010, there were convincing studies linking honey bee deaths to neonicotinoids, but though convincing, they were relatively few. Since then, many, many more studies have signalled the worrying risk that neonicotinoids pose to pollinators and other non-target invertebrates.
Here is a sample of just some of the studies, summarized elsewhere on this website.
Apologies for the inconsistant manner in which these studies are listed and referenced, owing to a combination of the way in which this website has evolved over time (and as volume of evidence has increased), the insufficient resources and technical skills on my part to plan and manage it!) and the simple lack of time available to me. Hence the need to opt for speed and convenience, and so I am guitly of 'copying and pasting' from elsewhere on this site.
Nevertheless, studies are listed here, sometimes with papers available to download, and you may be able to acquire
further studies by researching yourself on the internet. In addition, 1,121 studies up to 2014 were examined and referenced in the The World Wide Integrated
Assessment of the Impact of Systemic Pesticides on Biodiversity and Ecosystems.
