      Dear Dave,
      This is one paper of a few.  Try googling with google scholar.

      Organic is not necessarily pesticide free. And some pesticides that are approved for organic use are toxic to bees. There's some gain by organic practices, but it's not automatic, and bee losses can occur if the pesticides are wrongfully used.
