Xerces society report on Neonicotinoids.

The Xerces Society is an environmental organization that focuses on invertebrates which are essential to biological diversity. It is an international non-profit organization that advocates for invertebrates and their habitats by working with scientists, land managers, educators, and citizens on conservation and education projects. Core programs focus on endangered species, native pollinators, and watershed health.

This report has some useful information, especially on LD50s, and toxicity of different products. I have been trying to dig out this information and found it here in a series of tables in Chapter 5.

It is not without some bias, lets face it what isn't, but is a much better document than the PANNA report recently published and discussed in the environmental section here.

There is currently a thread open on Bee-L on this report.
