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.
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)
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!
