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 ...
Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees.
The alkali bee, Nomia melanderi, [1] is a ground-nesting bee native to deserts and semi-arid desert basins of the western United States. It was described by Theodore Dru Alison Cockerell in 1906. While solitary, these bees nest near each other and can form extremely dense aggregations in areas with favorable conditions.
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 ...
As many other pollinators, these bees collect nectar, pollen and resin from plants however, the Euglossine bees’ males also collect scents to create a right mixture of smells to attract females. They are also known as orchid bees and have four stages to complete, eggs are curved in shape that will hatch approximately 3 days.
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. Also, it may not be ...

Andrena prunorum, otherwise known as the purple miner bee, is a species of solitary bees in the family Andrenidae. [1] It is commonly found in the continental United States as well as much of North and Central America. [2] [3] Andrena prunorum is a spring-flying, ground-nesting bee that serves as a ubiquitous generalist in ecological settings ...
