    Ipm Ipm Presentation Transcript

    • Integrated Pest Management (IPM)
    • What is IPM?
      • 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.
    • 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 (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)
      • Example – Japanese beetle traps
    • Biological approach:
      • Introduction of a natural enemy of the pest
      • Example – Lady bugs feed on aphids and can be introduced to reduce the aphid population on crops
    • Chemical approach:
      • Pesticide applications that have minimal risks associated with their use
      • 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
    • Pheromones and IPM
      • Pheromones can be utilized to catch or deter insects
      • Example: Pheromone “traps”, which contain the pheromone emitted by the female gypsy moth can be set to catch male moths
    • 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
