Entomology experimental unit

The Entomology experimental unit develops methods to evaluate the effects of agricultural practices on pollinating insects. The challenge is to improve agricultural practices to protect pollinating insects within the framework of sustainable agriculture.

Wild or domestic, bees contribute to the pollination of 80% of species of flowering plants required for food. Bee populations are declining worldwide and numerous species are in danger. The causes of this decline, of which studies have focused mainly on the domestic bee, are multiple and interrelated. Studying bees and their interactions with their environment should provide keys to stopping this decline.
In all, 11 permanent staff work at the Entomology experimental unit located in Magneraud.


• Develop methods for evaluating the unintentional effects of pesticides on bees,
• Evaluate the effects of food resources provided by the agricultural environment and the landscape on the development of bee colonies


• Palynology laboratory to identify through microscopic observation the floral origin of the pollen brought back by the worker bees,
• Botanical and palynological database of over 400 nectar and pollen plants (http://guenievre.magneraud.inra.fr/entomologie/),
• 800 m² of laboratories and air-conditioned rooms for rearing insects,
• Indoor apiary of 10 beehives kept active during winter and an external apiary of 150 beehives,
• Ecobee facility for the observation of bees in an open environment in a 46 000 ha Plaine & Val de Sèvre workshop zone managed by the Inra/CNRS Agripop unit.
