Bumblebees (Bombus spp.): Bumblebees are large, robust bees known for their distinctive black and yellow coloration. They are important pollinators for a variety of crops.
Bumblebees are among the most charismatic of insects. Their robust frame and fuzziness combined with their charming habit of buzzing dutifully from flower to flower have brought joy to many of their onlookers. But why would you wish to step beyond these casual glances and handle these bees.
- Are active at temperatures near 40°F (5°C), and honeybees become active at temperatures near 60-65°F (15-18°C).
- Are active on cloudy, foggy, and rainy days. Honeybees are less active at low light levels.
- Will fly in winds of up to 40mph (64km/hr).
- Pollinate flowers through a method called “buzz pollination”, a rapid vibrating motion that releases large amounts of pollen onto the bee. In most situations, “buzz pollination” will allow a bumblebee to pollinate a flower in a single visit. A honeybee typically needs to visit a flower between 7-10 times before it is fully pollinated.
- Lack the sophisticated communication system of honeybees, and are less likely to leave your crop for more attractive flowers.
- Unlike honeybees, bumblebees are attracted to flowers with narrow corolla tubes, such as blueberries and cranberries.
- Are much more efficient pollinators than honeybees. They mainly forage for pollen rather than nectar, and transfer more pollen to the pistils with each visit.
- Promote higher rates of cross-pollination, as they forage between plants more randomly than honeybees.
- Visit many more blooms per minute than honeybees.
- Work earlier in the morning and later into the evening hours.
- Work better in tunnels, as they have a better sense of direction.
- Are safer for you and your employees. Bumblebees are non-swarming and much less aggressive than honeybees.
- Can be used in conjunction with honeybees to enhance pollination.
