Code(Credit) : ASEN 2102 (1-1-0)

Course Objectives

  • By the end of the course, the students will be able to know the influence of ecological factors on insect development and distribution, understand componenets of integrated pest management, know the classification of insecticides, and their use in pest management, and understand the mass multiplication techniques of major bio-agents.

Learning Outcomes

• Biotic and abiotic factors affecting insect ecology
• Pest Surveillance and Pest forecasting techniques
• Pest management methods including recent methods
• Beneficial insects and their mass multiplication techniques

• Acquaintance of insecticide formulations
• Sampling techniques for the estimation of insect population and damage
• Identification of major non –insect pests
• Acquaintance of mass multiplication techniques of important predators

Course Syllabus

Theory

• Insect Ecology: Introduction, Environment and its components.
• Effect of Abiotic factors–temperature, moisture, humidity, rainfall, light, atmospheric pressure and air currents.
• Effect of Biotic factors – food competition, natural and environmental resistance.
• Concepts of Balance of life in nature, biotic potential and environmental resistance and causes for outbreak of pests in agro-ecosystem.
• Pest surveillance and pest forecasting and Categories of pests.
• Host plant resistance

• Components/ tools of IPM, Cultural, Mechanical, Physical, Legislative, Biological (parasites, predators & transgenic plant pathogens such as bacteria, fungi and viruses).
• Chemical control-importance, hazards and limitations. Classification of insecticides, toxicity of insecticides and formulations of insecticides.
• Recent methods of pest control, repellents, anti-feedants, hormones, attractants, gamma radiation and genetic control. Practices, scope and limitations of IPM.
• Transgenic crops
• Insecticides Act 1968- Important provisions. Insecticide act 1969-important provisions.
• Application techniques of spray fluids.
• Phytotoxicity of insecticides.
• Symptoms of poisoning, first aid and antidotes.

• Beneficial insects: parasites and predators used in pest control and their mass multiplication techniques.
• Beneficial insects: Important species of pollinators, weed killers and scavengers, their importance.
Practical
• Study and distribution patterns of insects in crop eco systems –
• Sampling techniques for the estimation of insect population and damage-
• Pest surveillance through light traps, pheromone traps and fore casting of pest incidence
• Calculation of doses/ concentrations of different insecticidal formulations –
• Aquintance of insecticide formulations.
• Compatibility of pesticides with other agrochemicals and phytotoxicity of insecticides
• Aquintance of mass multiplication techniques of important predators; Cheilomenes, Chrsoperla and cryptolaemus.
• Important parasitoids; Egg, larval, and pupal parasitoids Viz., Trichogramma, Apanteles and Tetrastichus.
• Important Entomomorphogenic Fungi Beauveria bassiana and Nuclear Polyhedrosis Virus (NPV) on Helicoverpa and Spodoptera.
• Study of insect pollinators, weed killers and scavengers –
• Identification of major non –insect pests Viz., birds, crabs, snails, slugs and mammalians. House hold and veterinary insect pests.
