THEORY:

Importance of beneficial insects.

Bee keeping, pollinating plants and their cycle, bee biology, commercial methods of rearing. Equipment used. Seasonal management. Bee enemies and disease. Bee pasturage, bee foraging and communication. Insect pests and diseases of honey bee.

Types of silkworm.Voltinism and biology of silkworm. Mulberry cultivation, mulberry varieties and methods of harvesting and preservation of leaves. Rearing, mounting and harvesting of cocoons. Pests and diseases of silkworm, their management, rearing appliances of mulberry silkworm and methods of disinfection.

Species of Lac insect, morphology, biology, host plant, lac production – seed lac, button lac, shellac, lac- products.

Identification of major parasitoids and predators commonly being used in biological control. Insect orders bearing predators and parasitoids used in pest control and their mass multiplication techniques, important species of pollinators, weed killer and scavengers with their importance.

PRACTICAL:
