AbstractInsecticide resistance management (IRM) is a component of integrated pest management (IPM) that has the goal of forestalling resistance development to all insecticides. Since the advent of the organochlorine insecticides in the 1940s, an average of about one class of insecticide has been lost every 10 years because of resistance. Effective insecticides are necessary for optimum IPM and are too important and too expensive a resource to be lost so rapidly. By adhering to the principles of IPM and utilizing other IPM components such as biological and cultural control, IRM has the potential of conserving the susceptibility of pests to insecticides. Although initial attempts of IRM appear to be successful, it is imperative that research to undergird IRM be greatly accelerated.
