Integrated Pest Management (IPM)
What is IPM? Ecosystem-based strategy that focuses on prevention of pests through a combination of techniques.
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
Reasons for IPM Insects can become resistant to chemical pesticides Approximately 500 species of insects are resistant to one or more pesticides
How does IPM work? Reduces the amount of chemical pesticides by using three possible approaches: 1. Mechanical 2. Biological 3. Chemical
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
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
Chemical approach: Pesticide applications Using the least amount of chemicals that will still be effective
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
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
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. Will be presented
