Integrated Pest Management (IPM)
What is IPM?
EcosystemEcosystem-based strategy that focuses on long-term longprevention 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 ² 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 ´trapsµ, 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 pestsµ Must be closely monitored for best results Natural enemies of pests may become pests themselves
