Harvard study links pesticide use with colony collapse

Scientists in the past have been cautious about the connection between pesticides and honey bee collapse. However, lead author of the Harvard report, Chensheng (Alex) Lu has dismissed all caution and has made it clear that:

There is no question that neonicotinoids put a huge stress on the survival of honey bees in the environment. The evidence is clear that imidacloprid is likely the culprit for Colony Collapse Disorder via a very unique mechanism that has not been reported until our study.
