    News & Events August 2022 - Meet us at the CSEE-ESA conference in Montreal ​ Find the poster presenting our project and some preliminary results during the poster session on Monday August 15, 5-6:30 pm. May 2022 - The 2022 pitch begins! ​ It's spring, and bumble bee queens are emerging from hibernation. This is the period during which we initiate the various field studies: captures of bumble bee queens and evaluation of their health (with WPC), setting up studies in greenhouses to identify the associations of cultures favorable to bumblebees and interesting for agricultural producers.

July 2021 - pollen for native pollinators ​ Reproduction of wild-caught bumblebee queens is underway as part of our project on the benefits of native plant pollen for bumblebees in Quebec and Ontario.

Some resources may only be available in French, but please do not hesitate to contact us if you would like to know more. Serres et pollinisation, toute une organisation ! The pollination of crops in greenhouses requires the use of commercial hives of bumblebees (Bombus spp .). They are often carriers of diseases, which will be transmitted to wild bees, several species of which are already endangered. In addition, these commercial bumblebees, often limited by the diversity of food available in the greenhouse, can develop behavioral disorders, reducing pollination efficiency. ​ Solutions exist! » Large format poster ​ Sources (EN) : Article 1 - Article 2 - Article 3 ​ Sunflower has medicinal properties for bees, including bumble bees Research carried out by Prof. Lynn Adler's team has shown that sunflower pollen has medicinal value allowing honey bees (Apis mellifera ) and bumble bees (Bombus impatiens ) to heal, by getting rid of important intestinal parasites. But there are other plants with medicinal properties, such as thyme, purple digitalis or even linaria. Those plants, however, are not native to Northern America. Our research will now seek to identify native plants with similar properties. We are for instance investigating the medicinal values of Jerusalem artichoke (Helianthus tuberosus ), which belongs to the same family than the sunflower, or of the Canadian impatiens (Impatiens canadensis ) ​ Sources (EN): - Article 1 - Article 2 - Article 3 - Poster in pdf (c) Solange Barrault & Mathilde Tissier In pollinators' boots Pollinators are essential for agriculture and our food security. The production of our fruits, vegetables, seeds (strawberries, tomatoes, blueberries, sunflowers ...) depend on pollinators. In Canada, 70% of the pollination work is done by bees ... mostly wild bees! ​ Poster in pdf ​ (c) Poster: Solange Barrault & Mathilde Tissier

    Solutions for Farmers & Food for Bees News & Events La pollinisation des cultures en serres nécessite l'utilisation de ruches commerciales de bourdons (Bombus sp .), souvent porteuses de maladies, qui vont être transmises aux abeilles sauvages, dont plusieurs espèces sont déjà menacées. De plus, ces bourdons commerciaux, souvents limités dans la diversité alimentaire disponible en serre, peuvent développer des troubles comportementaux, réduisant l'efficacité de pollinisation. ​ Des solutions existent ! » Affiche grand format ​ Pollinator-friendly measures useful for farmers Are you a farmer or a beekeeper in Quebec or Ontario? We would like to know your opinion on the measures that you think are adapted to protect wild pollinators (bumblebees and other native bees) on farmlands. We invite you to answer this short anonymous survey of 5min. ​ Your answers will guide us in our scientific research, in order to propose developments favorable to relevant pollinators in the context of commercial production. Survey Current projects Multidisciplinary science for sustainable development: reconciling agriculture and the preservation of native pollinators in Canada In addition to this, you need to know more about it. Promote the health and nutrition of native pollinators Promote 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. ​ Image: a sunflower in a cornfield. Sunflowers have interesting nutritional and medicinal values ​​for pollinators. We are now looking to identify other plants with similar properties and adapted to our climate in Canada. 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. Qui sommes nous ? We are a group of conservation researchers and practitioners in Quebec, Ontario and Massachussets, working closely with producers, agronomists, entrepreneurs and policy makers. We seek to identify solutions for a sustainable agriculture that combine the socio-economic reality of farmers with the ecological and nutritional needs of native pollinators.
