Pollination Successful fruit set is essential in many horticultural and agricultural crops . Pollination, the key to fruit setting, is usually carried out by insects, animals, or by mechanical means . Historically, honeybees have been considered to be the best pollinators of agricultural and horticultural crops . However, in the late 1980’s it was discovered that bumblebees are far more effective than honeybees under many conditions . Bumblebees can be used effectively for the pollination of a variety of protected and open field crops . Why bumblebees? • Bumblebees are highly effective in pollinating crops in glasshouses/greenhouses, polytunnels and outdoor crops . • Bumblebees are less sensitive to low temperatures and low light intensity . • Bumblebees are more inclined to stay in the crop and they visit more flowers per minute . • Bumblebees are more inclined to work in adverse weather conditions . • Bumblebees are non-swarming and less aggressive . • Bumblebees do buzz pollination .
