Thousands of German bee-keepers are readying claims for compensation after scientists traced the cause of mass deaths among bees: a pesticide that coated maize seed.
German authorities have cracked the bee death mystery
Vast numbers of the insects were killed in the Rhine valley area of Germany's Baden-Wuerttemberg state by the chemical clothianidin, the Julius Kuehn Institute in the northern city of Braunschweig said.
The loss of swarms has worsened a long-term collapse in bee populations in many parts of the world that is blamed on the varroa mite infesting hives.
The research institute said late Friday 29 out of 30 dead bees it had checked had been killed by contact with the pesticide, which is harmless to humans but lethal to fruit flies and the corn rootworm (scientific name Diabrotica virgifera).
Farmers in Bavaria and Baden-Wuerttemberg used massive amounts of the pesticide this year in an effort to counter pests. The institute said it may have blown onto wild plants, fruit trees and rapeseed crops as it was sprayed.
The Baden Apiarists' Association, with 7,100 members, said Saturday it would study a compensation claim against farmers or the pesticide makers and would meet Monday with the state agriculture minister, Peter Hauk.
"The beekeepers have come to a point where they have to deal with securing their existence," said Ekkehard Huelsmann, chairman of the Apiarists' Association.
