Welcome to the University of Minnesota's electronic textbook of Integrated Pest Management, featuring contributed chapters by internationally recognized experts.

Our concept in creating this site is to provide an electronic alternative or complement to printed textbooks for communicating information on integrated pest management (IPM). Our objectives are to provide:

  1. a venue for easily maintaining and up-dating "state of the art" information from the world's leading experts on all aspects of IPM
  2. a resource economically deliverable anywhere in the world that can be freely downloaded and used by students, teachers, and IPM practitioners
  3. a forum for the international presentation of practical information and theory on IPM
  4. links to the vast and rapidly growing IPM resources available on the Internet including photographs and decision-support software

Since 1996, we’ve used this resource, supplemented with an electronic library of primary references and links to other IPM websites, as the textbook for our teaching of Insect Pest Managment at the University of Minnesota. More recently we have edited the hard copy IPM textbook, Integrated Pest Management: Concepts, Tactics, Strategies and Case Studies. The concept for a print textbook was that it and the online textbook could be complementary and cross-referenced. Thus, the print textbook is focused on theory, i.e., concepts and guiding principles, providing information of general application that will not become quickly dated, whereas information and specific examples that are more time-sensitive or situation-specific are communicated online.

IPM Success Story

Alfalfa Weevil
Hypera postica (Gyllenhal, 1813)
(Coleoptera: Curculionidae)

On three occasions, this destructive pest of alfalfa was accidentally introduced in North America. Alfalfa weevil has been the target of classical biological control efforts since its discovery in North America more than 90 years ago. These efforts have resulted in the establishment of at least 9 exotic parasitiods and egg predators. This once devastating pest is now largely controlled in the eastern U.S. by these natural enemies. See Alfalfa IPM to learn more about this impact.
