French researchers estimate that 73% of the increased colony collapse in 1994-2004 in areas of extensive agriculture in France has been caused by imidacloprid.

Abstract
Debates on causality are at the core of controversies as regards environmental changes. The present paper presents a new method for analyzing controversies on causality in a context of social debate and the results of its empirical testing. The case study used is the controversy as regards the role played by the insecticide Gaucho®, compared with other supposed causal factors, in the substantial honeybee (Apis mellifera L.) losses reported to have occurred in France between 1994 and 2004.
