The buzz grows about pesticides

There is growing evidence that common pesticides are playing a significant part in the recent decline of bees all over the world.

It is a worrying trend because bees are the most important pollinators of many wild flowers and agricultural crops. Disease may be causing some colonies to collapse, but recent studies have shown that chemicals in pesticides known as neonicotinoid, commonly sprayed on crops, are also harming bees.

This is backed up by a new study at Royal Holloway, University of London, which looked at the impact of multiple pesticides on bees. The results, published in  Nature, showed that exposure to low levels of multiple pesticides had subtle yet significant effects on the behaviour of  bees and the performance of colonies. Bees exposed to two pesticides performed worse than those exposed to one,  proving much less effective in bringing back pollen.

The study concluded that long-term exposure to low levels of multiple pesticides   This suggests that current methods of regulating pesticides are inadequate because they only consider lethal doses of single pesticides.

You can support the Bee Cause campaign by signing an online petition, which calls on the Government to suspend the use of neonicotinoid pesticides.
