15 April 2015 New publication linking imidacloprid to honey bee colony death

 

In this new article, the authors fed honey bee colonies with pollen substitute containing 3 different concentrations of imidacloprid, from common field-realistic (5 ppb) to worst case scenario (100 ppb). The authors could thus demonstrate a dose-effect relationship between exposure of honey bee colonies to imidacloprid and queen failure, increase in varroa mites and winter mortalities.

 

These interesting results with exposing colonies to a single pesticide (whereas in the environment they are exposed to many more) is one more evidence of neonicotinoid's toxicity to honey bee colonies.
