Honey bee pollination alone adds more than $15 billion in value to agricultural crops each year in the United States. Over the past few decades, there has been a significant loss of pollinators, including honey bees, native bees, birds, bats, and butterflies, from the environment.
If only a few species of plants depended on Loss of pollinators is especially devastating because there are so many plant species rely on them. More than 87.5% of angiosperms , over 75% of tropical tree species, and 30-40% of tree species in temperate regions depend on pollination and seed dispersal.
Honey bees pollinate many plant species that are not native to their natural habitat but are often inefficient pollinators of such plants; if they are visiting ten different species of flower, only a tenth of the pollen they carry may be the right species. Other bees tend to favor one species at a time, therefore do most of the actual pollination.
Pollinators are vital for functioning ecosystems, but many are endangered. One simple way to help is by hosting native plants. ... There are many to choose from, Carpenter said, and they don’t ...
Pollinator decline is the reduction in abundance of insect and other animal pollinators in many ecosystems ... although there is absolutely no evidence this has ...
Pollination is effected by the reverse procedure, in which one of the pollinia becomes trapped within the anther slit. Large-bodied hymenopterans (bees, wasps) are the most common and best pollinators, accounting for over 50% of all Asclepias pollination, [12] whereas monarch butterflies are poor pollinators of milkweed.

“Many popular fruits, nuts, and legumes require pollination, so increasing the number of pollinators that visit your garden can increase crop yields,” says Justine Kandra, horticulturist at ...
In many such cases, various native bees are vastly more efficient at pollination (e.g., with blueberries [4]), but the inefficiency of the honey bees is compensated for by using large numbers of hives, the total number of foragers thereby far exceeding the local abundance of native pollinators.
