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 ...
Bumblebees generally visit flowers that exhibit the bee pollination syndrome and these patches of flowers may be up to 1–2 km from their colony. [62] They tend to visit the same patches of flowers every day, as long as they continue to find nectar and pollen there, [63] a habit known as pollinator or flower constancy. While foraging ...
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
The term “pollinator syndrome” describes plant characteristics that might appeal to a specific type of pollinator, including color, scent, flower shape, and more. Bees see the world around us ...
It is believed that because solitary bees have very large, lipid-rich eggs the pollen provides the lipids and amino acids required for making these eggs. Pollen consumption is larger in younger females, and primarily occurs in the afternoon and evening as pollen collected early in the day goes toward larval provisioning.
The bees are directly exposed to the chemicals in two ways: by consuming nectar that has been directly treated with pesticide, or through physical contact with treated plants and flowers. Pesticides can impact the B. hortorum colonies by reducing brood development and also impairs their memory, preventing them from remembering the locations of ...
In other cases, generalist bees are just as, if not more, effective; pollination effectiveness may have less to do with female pollen provisioning and more to do with male mating competition. [9] In some cases, generalist Bombus species are more effective pollinators of Malvaceae flowers than the specialist P. bombiformis .
