  1. 1. Integrated Pest Management (IPM)
  2. 2. What is IPM? <ul><li>Ecosystem-based strategy that focuses on long-term prevention of pests or their damage through a combination of techniques such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties. </li></ul>
  3. 3. Reasons for IPM <ul><li>Chemical pesticides can impact the human health and ecosystems </li></ul><ul><li>Example: DDT, a pesticide, can accumulate in the fatty tissue of animals and affect bird reproduction </li></ul>
  4. 4. Reasons for IPM <ul><li>Insects can become resistant to chemical pesticides </li></ul><ul><li>Approximately 500 species of insects are resistant to one or more pesticides </li></ul>
  5. 5. How does IPM work? <ul><li>Reduces the amount of chemical pesticides by using three possible approaches: </li></ul><ul><ul><li>1. Mechanical </li></ul></ul><ul><ul><li>2. Biological </li></ul></ul><ul><ul><li>3. Chemical </li></ul></ul>
  6. 6. Mechanical approach: <ul><li>Limits the pest's access to food, water and harborage sites (i.e. proper storage of food/water supplies or installation or repair of physical barriers to future pest intrusion use of mechanical devices (i.e. traps) </li></ul><ul><li>Example – Japanese beetle traps </li></ul>
  7. 7. Biological approach: <ul><li>Introduction of a natural enemy of the pest </li></ul><ul><li>Example – Lady bugs feed on aphids and can be introduced to reduce the aphid population on crops </li></ul>
  8. 8. Chemical approach: <ul><li>Pesticide applications that have minimal risks associated with their use </li></ul><ul><li>Using the least amount of chemicals that will still be effective </li></ul>
  9. 9. Insects use of Pheromones <ul><li>Pheromones are chemicals emitted by an animal that signals another animal of the same species. </li></ul><ul><li>Example: female gypsy moths emit a pheromone to attract a male </li></ul>
  10. 10. Pheromones and IPM <ul><li>Pheromones can be utilized to catch or deter insects </li></ul><ul><li>Example: Pheromone “traps”, which contain the pheromone emitted by the female gypsy moth can be set to catch male moths </li></ul>
  11. 11. Advantages & Disadvantages of IPM <ul><li>Reduce chemicals being used </li></ul><ul><li>May reduce # of pesticide resistant insects </li></ul><ul><li>Only uses chemicals if necessary </li></ul><ul><li>Long term benefits (lower cost for chemicals, better for environment and human health) </li></ul><ul><li>Individual using IPM must be educated about the options </li></ul><ul><li>Takes more time to initiate than simply “spraying for pests” </li></ul><ul><li>Must be closely monitored for best results </li></ul><ul><li>Natural enemies of pests may become pests themselves </li></ul>
