ENT 602 ADVANCES IN BIOLOGICAL CONTROL                                                                                 (2L+1P) II

Objective
To appraise the students with advanced techniques in handling of different bioagents, modern methods of biological control and scope in cropping system-based pest management in agro- ecosystems.

Theory

UNIT I
Scopes of classical biological control and augmentative biocontrol; introduction and handling of natural enemies; nutrition of entomophagous insects and their hosts, dynamics of biocontrol agents vis-a-vis target pest populations.

UNIT II
Mass culturing techniques, immature stages of parasitic and predatory insects, insectary facilities and equipments, basic standards of insectary, viable mass-production unit, designs, precautions, good insectary practices.

UNIT III
National and international guidelines on natural enemy introduction; success stories of classical biological control, scope of fortuitous biological control due to liberalization in global trade in agriculture; international standards for testing side effects of pesticides on natural enemies; quality control parameters of parasitoid and predators, status of commercialization and field use of parasitoid and predators of important insect pests of crops, and beneficial insects and weeds.

UNIT IV
Colonization, techniques of release of natural enemies; recovery evaluation, conservation and augmentation of natural enemies; survivorship analysis and ecological manipulations; large-scale production of biocontrol agents, bankable project preparation.

UNIT V
Scope of genetically engineered microbes and parasitoids in biological control, and genetics of ideal traits in biocontrol agents for introgression and for progeny selections breeding techniques of biocontrol agents.

Practicals
Mass rearing and release of some commonly occurring indigenous natural enemies; assessment of role of natural enemies in reducing pest populations; testing side effects of pesticides on natural enemies; effect of semiochemicals on natural enemies, breeding of various biocontrol agents, performance of efficiency analyses on target pests, project document preparation for establishing a viable mass production unit/insectary.
