2. Integrated Pest Management (IPM)

3. What is IPM?
Ecosystem-based strategy that focuses on prevention of pests through a combination of techniques.

4. Reasons for IPM
Chemical pesticides can impact the human health and ecosystems
Example: DDT, a pesticide, can accumulate in the fatty tissue of animals and affect bird reproduction

5. Reasons for IPM Insects can become resistant to chemical pesticides
Approximately 500 species of insects are resistant to one or more pesticides

6. How does IPM work?
Reduces the amount of chemical pesticides by using three possible approaches:
1. Mechanical
2. Biological
3. Chemical

7. Mechanical approach:
Limits the pest's access to food, water and harborage sites)
Example – Japanese beetle traps
Cleaning field equipment
Planting certified seed
Quarantines
Proper storage of food/water supplies
Installation of physical barriers
Traps

8. Biological approach: Introduction of a natural enemy of the pest
Release of predators/parasites of an insect or weed
Manipulating the crop to withstand or tolerate pests
Natural breeding method
Genetically modified plants

9. Chemical approach: Pesticide applications
Using the least amount of chemicals that will still be effective

10. Insects use of Pheromones
Pheromones are chemicals emitted by an animal that signals another animal of the same species.
Example: female gypsy moths emit a pheromone to attract a male

11. Advantages & Disadvantages of IPM
Reduce chemicals being used
May reduce # of pesticide resistant insects
Only uses chemicals if necessary
Long term benefits (lower cost for chemicals, better for environment and human health)
Individual using IPM must be educated about the options
Takes more time to initiate than simply “spraying for pests”
Must be closely monitored for best results
Natural enemies of pests may become pests themselves

12. IPM Case Your team will be given a specific situation.
Read about the situation
Develop a specific IPM to sustainable solve the problem
Rough draft on back of you case handout
Final draft on white.
