A study published in Nature shows that low-level exposure to a combination of two pesticides is more harmful to bumblebee colonies than either pesticide on its own.

Low doses of pesticides have subtle effects on individual bees and can seriously harm colonies. The authors hope that his work will feed into consultations on pesticide regulations that are happening now in Europe.
