 Over 2 years of study, Randolf has shown that these doses neonicotinoids do affect bees' higher cognitive¹ processes, especially their memory of the landscape around them.-We tested about 200 bees, both controlled bees and pestcide-treated bees, and we've found that controlled bees are just fantastic. They find home quickly. They use victualler and landscape memory and they do fine. Now the treated bees depending on doses aim to subsistence, we find that they are kind of more confused. They usually do quite well, when they fly along with the victualler, but when they need to refer to the landscape memory, then usually they are lost. They change their behavior in a very sound way, so that simply means to me that neonicotinoids are endangered to honey bees.

It's work like this that lies behind European Commission² ban. But one thing I've learned in this detective story is that it's all too easy to jump to conclusions. Despite this research though, neonicotinoids are still at the center of a huge controversy³.

The UK government did not support the EC ban on neonicotinoids. It said there wasn't enough evidence to justify⁴ it.
