The evaluation of risk to pollinators by nectar sampling

The two Poll-Ole-GI SUDOE partners in France, units Apis from INRA and Agripop from INRA/CNRS, seek to evaluate risks of insecticides to pollinators by sampling nectar in oleaginous crops.

During spring period, rapeseed crops provide important resources to pollinators in SUDOE regions. The blooming occurs between April and May and flowers contain very attractive nectar which is valuable to honey bees as well as wild pollinators. One of the objectives of the Poll-Ole-GI project is to evaluate toxicological risks to pollinators and the dispersal of agrochemicals in their environment.

In 2018, teams of the Apis unit in Magneraud and the Apis unit in Chizé have conducted nectar sampling in 27 agricultural lands. Samples are collected directly in rapeseed flowers using micro capillary tubes. 49 samples have been collected over 5 days.
