Dr Nigel Raine, a bee researcher at Royal Holloway, has welcomed the result of an EU vote to introduce a ban of three pesticides believed to be harmful to bees.
He told ITV News it was "good news" and when the ban comes into effect it will be "crucial" to monitor bee populations to make sure it is effective.
He added that "we need to think about what we're going to use instead".
