That's why I'm heading to south Sussex. I've heard about an experiment happening right now to establish how much pesticide1 bees are really getting in the wild. So I'm joining in Professor Dave Goulson and his team to find out how they are going to do it.-The dispute largely focuses on the fact that's pretty much all these experiments done today, have exposed the bees to the pesticides2 in an unnatural3 way, and what we really don't know is actually what wild bees, natural free-flying bees, are actually exposed to, because in the real world, they have a choice about where they can forage4. There are lots of plains around. They might, for example, be avoidable with pesticides, and if they did, that would mean that actually they might be exposed to less than we think.
To find out how much pesticide wild bees are really exposed to, he set up a series of bumblebees in fields around east Sussex. Each started with just a handful of bees. Three weeks later, they are flourishing. New colonies pecked with nectar and
pollen5 collected from the surrounding fields.
-I'm always told bumblebees sting more painful than regular bees. Is that right?
-I don't know. I mean, there isn't much in it. They both are...
-So what we need to do is to get ...
-A pollen sample, and a nectar sample, and a sample of the wax, and then we've got all samples in. We gonna analyse them all to detect these tiny phases of pesticides.
The bees will have these all pached-up in a day or two. The team will collect samples every few weeks, but this will give them the first real measure of the dose that wild bees are getting. They've chosen to study bumblebees for a good reason, because each colony lives for just one year.
