Abstract

The authors confirmed pesticide toxicosis of honey bees in 151 cases during a five year period (2007-2011). A suddenly occurring mass bee death is always ground of suspicion for toxicosis. The suspicion is further confirmed by the presence of an exceptional number of shivering, unable to fly, proboscis stretching bees in hives and in their closer surroundings. The toxicosis becomes even more evident when huge bee losses with identical symptoms are observed in the near-by apiaries and also turns out that pesticides were used within the flight of the bees in the past days. 222 honey bee samples and 129 plant samples were sent for veterinary diagnostic laboratory examination. The presence of contagious diseases was excluded and 12 different pesticides were detected (by GC-MS, GC-NPD and HPLC) in 151 honey bee samples. In 64 cases the plant samples contained the same pesticide(s) as the honey bees from the given poisoning case, thus confirming the dependence of an effect upon a cause, namely the application of pesticides upon bee poisoning. Poisonings are most frequently caused by chloropyriphos and dimethoate (organophosphate chemical family), fipronil (phenylpyrazole chemical family) and six types of synthetic pyrethroids. The recited cases call attention to the fact that the application of pesticides in agriculture causes very often huge expenses linked to honey bee poisonings. The overall losses could be minimised by respecting the rules mentioned in licences and users guide.
