define the term ;-sericulture,mriculture and opiculture

Let me correct you first, it is not Mriculture and Opiculture. The correct terms are, Moriculture and Apiculture.

The rearing and management of the silk worms to obtain silk is called sericulture.

The cultivatation of mulberry trees to increase the silk production is called moriculture.

The  rearing and management of honeybees to get honey and Wax is called apiculture.
