Credit: 2(1+1)

THEORY:

General account on nature and type of damage by different arthropods pests: Scientific name, order, family, host range, distribution, biology, nature of damage and management of insect pests of Cereals-Rice –  Paddy stem borer, Green leaf hopper, Brown plant hopper, White backed plant hopper, Gall midge, Paddy grasshopper, Blue beetle, Caseworm, Armyworm, Gundhi bug, Hispa, Leaf folder. Sorghum – Shoot fly, Stem borer, Aphids, Delphacids, Grasshopper, Earhead midge, Earhead caterpillars. Maize – Shoot fly, Stem borer, Armyworm, Cob earworm. Bajra – Shoot fly, Blister beetle. Wheat – Stem borer, Aphids, Termites. Minor millets. Pulses – Pigeon pea, chickpea, mungbean, urdbean, cowpea, pea. Pigeon pea – Pod borer, Plume moth, Pod fly, Spotted pod borer, Leaf webber, Mites. Chickpea – Gram pod borer, Aphids, Cutworm. Mung and Urdbean – Aphids, Leaf eating caterpillar, Semilooper, Pod borer. Cowpea and Pea – Aphids, Blue butterfly, Pod borer. Oilseeds -Groundnut – Leaf miner, Hairy caterpillar, Tobacco leaf eating caterpillar, Aphids, Thrips, White grub, Pod sucking bug.  Castor – Semilooper, Capsule borer, Jassids, Tobacco leaf eating caterpillar. Sunflower – Capitulum borer, Hairy caterpillar, Jassids, Thrips, Whitefly, Stem borer. Safflower- aphids, Capitulum borer, Guzia weevil. Mustard – Aphids, Sawfly, Leaf webber. Linseed – Gall fly. Soybean – Stem fly, Girdle beetle, Leaf miner, Tobacco leaf eating caterpillar, Whitefly, Semilooper, Gram pod borer. Sesamum –Til hawk moth, Gall fly, leaf eating caterpillar.  Niger –Semilooper, Gram pod borer. Fiber crops –Cotton – Aphids, Jassids, Thrips, Whitefly, Mealy bugs, Spotted bollworm, American bollworm, Pink bollworm, Tobacco leaf eating caterpillar, Leaf folder, Semilooper, Red cotton bug, Dusky cotton bug, Grey weevil. Sunhemp and Mesta – Sunhemp hairy caterpillar. Sugarcane crops – Early shoot borer, Internode borer, Top shoot borer, Whitefly, Pyrilla, Woolly aphids, Mealy bug, Scale insect, Termites, White grub. Non-insect pests of above crops – Crabs, Snails and Slugs,  millepedes, Mites, Rats and squirrels. Stored grain pests – Biology and damage of Primary and Secondary pests. Primary store grain pests- Internal feeders – Rice weevil, lesser grain borer, pulse beetle and Angoumois grain moth. External feeders – khapra beetle, Indian meal moth. Secondary store grain pests – Rust red flour beetle, Saw toothed grain beetle, Long headed beetle. Primary and Secondary store grain pests – Rice moth. Non insect pests, mites, rodents, birds and microorganisms associated with stored grain and their management. Preventive and curative methods of stored grain pests. Storage structure and methods of grain storage and fundamental principles of grain store management.

PRACTICALS:

Identification of different type of damage. Identification and study of life cycle and seasonal history of various insect pests attacking crops and their produce. Field crops: Cereals-Rice, Sorghum, Maize, Bajra, Wheat  and  Miner millets. Pulses- Pigeon pea, Chickpea, Mung bean, Urd bean, Cowpea and Pea. Oilseeds: Groundnut, Castor, Sunflower, Safflower, Mustard, Linseed, Soybean, Sesamum and Niger. Fibre: Cotton, Sunhemp and Mesta. Sugar crop: sugarcane. Non insect pests of field crops. Store grain pests. Non insect pests, mites, rodents, birds and microorganisms associated with stored grain and their management. Preventive and curative methods of stored grain pests. Storage structure and methods of grain storage and fundamental principles of grain store management.
