Multidisciplinary science for sustainable development: reconciling agriculture and the preservation of native pollinators in Canada
News & Events
Pollen collection for the 2025 season begins!
May 2025
Spring is here, and with it, the first blooms! We're starting to collect various pollens in order to learn more about their nutritional values for pollinators and to assess their complementarity with the main crops of Quebec and Ontario. The stars of the moment: willows! Collecting began even earlier in France, with hazelnuts already in bloom at the end of February in the north-east of the country. The French teams also collected pollen from maples and willows, which will enable us to compare the nutritional value of pollen from different countries.

Psst! We're also preparing a series of fact sheets to help you make the best choices and associations with your own plants. Stay tuned!
Our approach
Promoting the health and nutrition of native pollinators
Promoting the health and sustainability of agricultural production
Consideration of the economic and social reality of farmers
The establishment of sustainable agriculture requires integrating the interests of all stakeholders. This entails considering the needs and obstacles faced by producers when initiating research projects. We conduct surveys and interviews with farmers in Ontario and Quebec to assess their main interests and limitations in implementing bumblebee-friendly management practices. These surveys will also allow us to integrate their suggestions and recommendations to identify plants and associations of high agro-economic value to include in our experiments on the health and performance of bumblebees.
Nutritional complementarity of cultivated and native plants for bumblebees
Monocultures restrict pollinators to a monotonous, often deficient diet, increasing the risk of disease and reducing pollination and reproductive performance. We seek to identify the best combinations of plants (cultivated or cultivated-indigenous) providing a nutritious pollen resource adapted to bumblebees over an annual cycle, in order to target the combinations to be favored in agricultural environments to fight against malnutrition and decline of colonies.

Improving the health of bumblebees in greenhouses to preserve wild pollinators
Commercial bumblebees are used on a large scale for the pollination of greenhouse crops. However, they often have a low resistance to diseases, and may thus pose an additional threat to wild bees, by increasing the transmission of parasites. We want to test to what extent the establishment of sunflower strips, whose pollen possesses medicinal values, operates as a simple and effective solution to reduce the parasitic load of commercial bumblebees in greenhouses before they enter in contact with wild bumblebees and other native bees.
