IPM Nature and approach with biological control.pptx

Insect pest management is a comprehensive strategy, often referred to as Integrated Pest Management (IPM), that uses a combination of biological, cultural, mechanical, and chemical controls to reduce pest populations to acceptable levels while minimizing risks to people and the environment

1. Prepared by Dr. Neelesh Raypuriya Department of Entomology College of Agriculture, Indore Rajmata Vijayaraje Scindia Krishi Vishwavidyalaya, Gwalior Topic: Integrated Pest Management

2. Key points of IPM Integration Harmonious use of multiple methods to control single pests or pest complexes Pest An organism detrimental to humans, including: invertebrates, vertebrates, weeds, and pathogens Management Decisions based on ecological principles and economic and social considerations

3. Three important components of IPM Economic injury level Lowest population density that will cause economic damage Economic threshold Population size large enough to trigger an action to prevent an increasing pest population from reaching the economic injury level General equilibrium position Average density of a population over time

4. Basic principles of integrated pest management Identification of key pests and beneficial organisms Monitoring of pest Defining the management unit i.e . Agroecosystem Development of management strategy Establishing Economic thresholds (Loss and Risk) Developement of Assesment techniques Evolving descriptions of predictive pest models

5. Methods of monitoring Visual inspection Pheromone traps Sticky traps Sweep nets

14. Cultural methods Use of resistant varieties Crop rotation Crop refuse destruction Tillage of soil Variation in time of planting or harvesting Pruning or thinning and proper spacing Judicious and balanced use of fertilizers Crop sanitation Water management trap crops

15. Mechanical methods

16. Physical methods

17. Biological control

18. Genetic methods Use of sterile male technique

19. E stablishing economic thresholds (loss and risk) Level of pest population that action should be taken to prevent harm Action threshold is based on visual damage or health Economic threshold is the level at which cost of harm (yield) exceeds cost of control
