Integrated Pest Management (IPM)


What is ipm l.jpg

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 l.jpg

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 ipm4 l.jpg

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 l.jpg

How does IPM work?

  • Reduces the amount of chemical pesticides by using three possible approaches:

    • 1. Mechanical

    • 2. Biological

    • 3. Chemical


Mechanical approach l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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

Advantages & Disadvantages of IPM
