Case Study 1: Honey is widely used and therefore beekeeping for making honey has become an agricultural enterprise. Since bee-keeping needs low investments, farmers use it as an additional income-generating activity. In addition to honey, the beehives are a source of wax that is used in various medicinal preparations. The local varieties of bees used for commercial honey production are Apisceranaindica, commonly known as the Indian bee, A. dorsata, the rock bee, and A. florae, the little bee. An Italian bee variety, A. mellifera, has also been brought in to increase the yield of honey.
The Italian bees have a high honey collection capacity. They sting somewhat less. They stay in a given beehive for long periods and breed very well. For commercial honey production, bee farms or apiaries are established. The value or quality of honey depends upon the pasturage, or the flowers available to the bees for nectar and pollen collection. In addition to an adequate quantity of pasturage, the kind of flowers available will determine the taste of the honey.
