The measures implemented to reduce the impact of plant protection products on pollinators in France

Abstract

Shortly after the introduction of systemic insecticides, new problems were observed by beekeepers on honeybee colonies. The studies carried out under laboratory conditions have shown sublethal effects on honeybee behavior. However, it was not possible to reproduce under natural conditions the effects described by beekeepers on bee colonies. In addition, studies have revealed that many other factors could also be responsible for the dysfunction of honeybee colonies. Scientists agree that problems observed on the hives are the result of multifactorial effects. Measures concerning apicultural and agricultural practices are therefore necessary to improve honeybee colonies' health and to preserve the diversity of pollinators in France.
