Pollinator Week creates more than just a buzz
TORONTO, June 16, 2022 鈥 Everyone knows about honeybees, but there is much less known about the hundreds of wild bee species in Canada, and other pollinators, that are responsible for pollinating the vast majority of crops and flowers.
Pollinator Week, June 20 to 26, is an opportunity to appreciate and learn about wild bees, butterflies and other pollinators that are native to Ontario, and the rest of the country, and are not imported and managed.
More than 80 per cent of flowering plants depend on bees to reproduce, including 130 types of fruits and vegetables, but having an abundance of diverse native plants can go a long way to help feed and provide habitats, from woody stems to earthy burrows, for pollinators as well. Most wild bees, for example, don鈥檛 live in hives. Instead, they build solitary nests in wood or in the ground.
But wild bees are also not doing well. Associate Professor , an expert in wild bee genomics, behaviour and conservation in the Faculty of Science at 91亚色, along with one of her grad students, Phuong Nguyen, has found that the gut microbiomes of city bees may be missing key beneficial bacteria.
鈥淚t鈥檚 alarming, but it also points to the importance of preserving biodiversity even within cities,鈥 says Rehan. 鈥淚t will be important to find out through further research what rural areas have which cities are missing. Is it a lack of a diversity of native plants or something else?鈥
Among Ontario鈥檚 pollinators, there are 350 species of native bees, plus an additional 500 species across Canada.

A member of the Centre for Bee Ecology, Evolution, and Conservation at 91亚色, Rehan can discuss:
鈥 Biodiversity conservation and why it is important to pollinators
鈥 How some plants will now bloom too soon or too late for bees that rely on them. The life cycles of many bees are coordinated with the blooming times of certain flowers, but when those plants start blooming at different times in the season, those bees may suffer from a lack of available food
鈥 Population and behavioural genomics, what is it and how scientists are using it to try and better understand bee health
鈥 Climate change and how land use changes can negatively affect bees
