This is a list of crop plants pollinated by bees along with how much crop yield is improved by bee pollination. [1] Most of them are pollinated in whole or part by honey bees and by the crop's natural pollinators such as bumblebees, orchard bees, squash bees, and solitary bees. Where the same plants have non-bee pollinators such as birds or ...
Because bumblebees do not overwinter the entire colony, they do not stockpile honey, and therefore are not useful as honey producers. Bumblebees are increasingly cultured for agricultural use as pollinators, among other reasons because they can pollinate plants such as tomato in greenhouses by buzz pollination whereas other pollinators cannot ...
Buzz pollination or sonication is a technique used by some bees, such as solitary bees and bumblebees, to release pollen which is more or less firmly held by the anthers. [1] The anthers of buzz-pollinated plant species are typically tubular, with an opening at only one end, and the pollen inside is smooth-grained and firmly attached.
Honey bees are attracted to nectar and pollen from the staminate and hermaphrodite papaya flowers, but narrow tubes and deep flowers may limit the effectiveness of bees as primary pollinators. [2] Even so, pollen requirements for healthy and consistent fruit motivate growers to locate honeybees within their groves to pollinate in any capacity.
Bombus impatiens, the common eastern bumblebee, is the most commonly encountered bumblebee across much of eastern North America. [3] They can be found in the Eastern temperate forest region of the eastern United States , southern Canada , and the eastern Great Plains . [ 4 ]
Bees do not build nests and instead rely on finding abandoned rodent dens, hollow logs, suitable man-made structures, or tussocks. Queens will hibernate in loose dirt or rotting logs. [8] This bumble bee is very common and has been experiencing steady growth unlike many other bumble bees that are in decline. [10]
Bombus terrestris, the buff-tailed bumblebee or large earth bumblebee, is one of the most numerous bumblebee species in Europe. It is one of the main species used in greenhouse pollination , and so can be found in many countries and areas where it is not native, such as Tasmania . [ 2 ]
Western bumble bees are generalist foragers. [8] Because they do not depend on any one flower type, they are considered to be excellent pollinators. bumble bees are also able to fly in cooler temperatures and lower flight levels than many other bees. [9] Additionally, bumble bees perform "buzz pollination".
