Honeybees produce honey. In USA., 6 million colonies of honey bees produce about 150,000 tons of honey annually, which serves as human food and medicine. In Pakistan honeybee culture is gaining potential as a cottage industry.

The number of silkworms employed in service of man can be imagined by the fact that nearly 23 million kg silk are used in the world every year.
