1 Integrated Pest Management (IPM)

2 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.

3 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

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

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

6 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

7 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

8 Chemical approach:  Pesticide applications that have minimal risks associated with their use  Using the least amount of chemicals that will still be effective

9 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

10 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

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
