and then click on the "download PDF" link

The reason for me posting this is that Lennard Pisa was a member of
bee-l and may still be on the list so for a change we could discuss
the paper directly with the author.

Some of the other authors, such as Belzunces and Bonmatin have been
studying neonics for over 25 years.
