What does IPM do?

Employs a Sustainable Approach

Integrated pest management, or IPM, is a sustainable approach that emphasizes ecosystem-based strategies that result in economical and long-term solutions to pest problems. The objective for IPM practitioners is to minimize risks to human health and the environment from the pest management actions implemented. IPM is a holistic approach that seeks to manage pests by using methods that are effective, economically sound, and ecologically compatible. IPM practitioners base decisions on information that is collected systematically as they integrate economic, environmental, and social goals.

Integrates Multiple Tactics in a Variety of Settings

IPM promotes the use and integration of multiple tactics such as biological control, use of resistant varieties, behavioral modification, and mechanical and cultural controls for pest management. A special emphasis is placed on prevention of the pest problem and on control by natural enemies of the pest organism. Preventive steps, for example, would include using mesh screening in greenhouses or in homes to prevent insect pest entry. Control by natural enemies encompasses examples such as aphids being killed by ladybird beetles or Japanese beetle grubs being killed by Tiphia parasitic wasps. The principles of IPM can be applied in a variety of settings, such as agricultural crops, residences and buildings, urban landscapes, forests, recreational areas, and other managed ecosystems.

Selects the Proper Tools

Early proponents of the IPM approach noted that reliance on natural enemies of the pests was necessary and that chemical pesticides would play a role only when this and other preventive steps failed. Taking steps to manage pests using an IPM approach promotes a sustainable form of pest management. In this case, the tools to manage the pest are selected so that they pose the least risk to the environment and to human health. Thus, in IPM the application of pesticides is done only when necessary to avoid damage to the managed resource or to protect human health. Pesticides are used only after documenting that they are needed according to established guidelines. Moreover, steps are taken to promote the action of pests' natural enemies and to protect them. Noted entomologist Carl Huffaker emphasized that "when we kill off the natural enemies of a pest, we inherit their work".

Educates People in Connecticut

The College of Agriculture and Natural Resources is home to UConn's Integrated Pest Management program. The Connecticut IPM program educates growers and the general public on environmentally sound pest management tactics. The goals of the program are to provide information on how to effectively control pests using a variety of pest management methods. IPM educational programs provide information on pest management alternatives through field training, conferences, workshops, and publications. Regular pest alerts are also provided through email and the IPM Web site.

Employs Many Methods

  • Cultural controls: Sanitation, crop rotation, planting time selection
  • Physical and mechanical controls: Sticky traps, fences, row covers
  • Host plant resistance: Use of resistant varieties.
  • Behavioral modification: Use of insect pheromones, use of scare tactics
  • Biological control: Use of beneficial organisms like insect predators, insect pathogens and antagonists of plant pathogens.
  • Pesticides: Use of conventional chemical pesticides and biorational pesticides
  • Regulatory or legislative prevention: Quarantine programs
