DESCRIPTION OF COURSES
ENT 604 INSECT NUTRITION AND HOST PLANT RESISTANCE (2L+1P) III
To familiarize the students with types, basis, mechanisms and genetics of resistance in plants to insects and role of plant resistance in pest management. nutritional physiology and their application in entomology.
History and importance of resistance, principles, classification, components, types and mechanisms of resistance.
Insect-host plant relationships; theories and basis of host plant selection in phytophagous insects.
Chemical ecology, tritrophic relations, volatiles and secondary plant substances; basis of resistance; induced and acquired resistance.
Factors affecting plant resistance including biotypes and measures to combat them.
Screening techniques; breeding for insect resistance in crop plants; exploitation of wild plant species; gene transfer; successful examples of resistant crop varieties in India and world. Role of biotechnology in plant resistance to insects.
Insect nutrition - role of vitamins, proteins amino acids, carbohydrates, lipids, minerals and other food constituents; extra and intra-cellular micro-organisms and their role in physiology, artificial diets.
Screening techniques for measuring resistance, measurement of plant characters and working out their correlations with plant resistance; testing of resistance in important crops; bioassay of plant extracts of susceptible/resistant varieties; demonstration of antibiosis, tolerance and antixenosis.
