Dear fellow beekeepers,

on Frebruary 16, 2011, the dutch toxicologist Dr. Henk Tennekes gave a lecture at the Institute of Public Health, University of Heidelberg (Germany). This lecture is about "Toxicity as function of exposure time - Risk profile of neonicotinoid insecticides".

It was originally given in german, but yesterday I visited him to record an english version of his lecture for the international beekeeping community.

You can see and listen to this video on youtube:

Greetings from Germany,
