I'm new to this forum ... and was interested to read this thread.
I'm a beekeeper, and was delighted to see that the neonictinoides should now be banned (despite the UK vote against). A two year moratorium will be helpful ... but I have heard that the pesticide could remain in the soil for a long time ... so it may be difficult to really judge the effects.
The bees have had a hard time of it lately. The poor summer has meant that many queens were not properly mated ... and the long winter / cold spring have also contributed to winter losses.
What we really need now is a warm settled spell to allow those hives which have survived to begin to get going.
Final point ... can I put in a plea for dandelions? A useful early pollen source for honey bees ... and a pretty, sunny flower too!
