insects. The decline of honey bees has been attributed to a number of factors, but one of the most significant is the use of neonicotinoids, which are widely used in the U.S. to protect crops from pests.
These pesticides have been shown to harm bees by impairing their ability to forage for nectar and pollen. In addition, they have also been linked to colony collapse disorder (CCD), which is characterized by the sudden disappearance of bees from a hive.

What percentage of the world’s crops rely on pollinators?
About 35 percent of the world’s food crops are dependent on animal pollination, and three-fourths of the world’s flowering plants are. Native bees help increase pollination by pollinating flowers, fruits, nuts, seeds, and other plants.
States, honey bees are the most important pollinator, but they are not the only bees that help pollinate crops. below)

such as wasps
as well as birds and mammals
Bees in the U.S. Pollinators are found in all 50 states, the District of Columbia, Puerto Rico, Guam, American Samoa and the Northern Mariana Islands.
They are also found on the island of Hawai’i, which is home to more than 1,000 species, including the Hawaiian honey bee. Hawaiian bee is the largest bee in North America, with a wingspan of up to 2.5 inches (6 centimeters) and a body length of about 1.2 inches.
How many crop plants do bees pollinate?
Bee pollination is used in the production of more than 90 crops. European honey bee2 is the most important of the 3,600 bee species that live in the U.S. In the United States, honey bees are responsible for pollinating about 80 percent of the crops grown in agriculture. European bee is a solitary, solitary bee. It lives in colonies of up to 100,000 bees, and is solitary in that it does not associate with other bees or other species of bees.
European bees do not mate with each other. This means that they cannot interbreed with non-European bees such as the American bumblebee (Bombus terrestris) or the Africanized bee (Bombyx mori), which are also speciesless. Because of this, it is not possible to breed European and American bees to produce a hybrid that would be genetically identical to either of these two species.
How much of our food do bees make?
Pollinators, most often honey bees, are responsible for one in every three bites of food we take, and increase our nation’s crop values each year by more than $15 billion. Due to a variety of factors, honey bees have been in decline in the U.S. for more than three decades.
Honey bees are not the only pollinators that are under threat, but they are by far the most important. According to the United States Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS), the number of honey bee colonies has declined by nearly 50 percent since the mid-1970s.
This decline is due in large part to Colony Collapse Disorder (CCD), which is caused by a combination of diseases, parasites and pesticides. CCD is the result of a complex web of interactions between bees and their environment, which can lead to colony collapse disorder, or “black swan” events, in which millions of bees die in a short period of time.
Do bees make 1/3 of our food?
One third of the food we eat comes from pollination due to honeybees. It is about one in every three bites of food. One third of the pollination is done from one species of bee, the honeybee. The other two thirds are done by other insects, such as butterflies, moths, beetles, ants, and so on.
They pollinate more than 90% of all fruits, vegetables, flowers, nuts and seeds. States alone, they are responsible for the production of over $1 billion worth of fruits and vegetables each year. Honeybees have been around since the beginning of recorded history and are considered to be the oldest living organisms on the planet.
What would happen if all bees went extinct?
Without bees, the availability and diversity of fresh produce would decline substantially, and human nutrition would likely suffer. Crops that would not be cost-effective to hand- or robot-pollinate would likely be lost or persist only with the dedication of dedicated pollinators. States, for example, one-third of the fruits and vegetables consumed by Americans each year are pollinated by bees.
This is equivalent to more than 1.5 billion pounds of fruit and vegetable per year, or enough to feed the entire U.S. population for an entire year. (FAO) estimates that the world’s population will increase from 7 billion today to 9 billion by 2050. As a result, food production will have to be increased dramatically to meet the growing demand for food and other resources.
What percentage of plants are pollinated by insects?
According to the usda, at least 75 percent of flowering plants are pollinated by bees. Bees are responsible for pollinating more than half of the fruits and vegetables grown in the United States. They also pollinate many other plants such as tomatoes; (Check list below)
- Other fruits
The pollination services provided by honeybees are estimated to be worth $1.5 billion annually. .
