To sensitize about the use of nematodes for the biological control of insects, other arthropod and invertebrate pests of crops.
Beneficial nematode fauna- predators, parasites of insects, molluscs and other pests; Entomophilic nematodes- important groups, types of nematodeinsect associations; taxonomic characteristics of nematode parasites of insects.
Host-parasite relations and life cycle of mermithids, entaphelenchids, thelastomids, sphaerularids, allantonematids and Iotonchids.
Entomopathogenic nematodes- Steiner nematids and Heterorhabditids, their mor phological characteristics, taxonomic status, biology, nematode-bacterium symbiosis and virulence mechanism.
Entomopathogenic nematodes- mass multiplication techniques, formulations, field applications and efficacy, success stories.
Entomopathogenic nematodes- Ecological considerations, compatibility with various agrochemicals and their use in IPM.
Isolation of EPN from soil by baiting; Collection of insects and detection of nematodes; General morphology and taxonomic outline of EPN; General microscopic features of Mermithids, Rhabditids, Thelastomatids, Diplogasterids, Tylenchids etc.; Killing, fixing, preparation of permanent mounts of EPN; Isolation and culturing of symbiotic bacteria; Formulation of EPN and symbiotic bacteria; Laboratory bioassay of EPN/bacteria against insects.
