Integrated pest management regulates pests by using a variety of control measures, including mechanical, cultural, biological, and chemical. IPM has extended beyond insects to management of all pest populations: weeds, disease organisms, and mammals. Implement a treatment strategy using mechanical, cultural, biological, or chemical controls, or a combination of these strategies. A threshold is the point at which action should be taken. Assess and consider economic or aesthetic injury thresholds. Monitor and scout insects to determine insect types and population levels. Early proponents of IPM suggested using five basic strategies to improve insect management: Integrated pest management was first suggested by entomologists because insects were the first group of pests to prove difficult to manage with chemicals alone. Pests are much less likely to survive a program that uses many different methods of reducing their populations. An IPM plan allows some level of pests in the environment. Integrated refers to the fact that all control measures (mechanical, cultural, biological, and chemical) are considered and used as appropriate. This new approach was described as integrated pest management (IPM). Scientists began to develop a new approach to pest control. Instead, overuse of pesticides caused the development of resistant pests. It became clear that pesticides alone would not solve all pest problems. Pests susceptible to a pesticide were quickly killed, leaving resistant ones to breed and multiply. When modern pesticides were first developed, they were used extensively. We will be more successful in managing unwanted species when we realize that these organisms follow predictable patterns that we can use to our advantage. Only humans consider certain species pests when they occur where they are not wanted. What we call "pests" are part of a natural system at work. Many cultivated plants are not as competitive as many of our natives, weeds, or pests cultivated plants survive only with the constant help and intervention of the gardener. A weed growing in a lawn represents the first stage in a sequence of events that, if allowed to continue, could eventually result in a forest. After planting a garden or establishing a lawn, the natural process of plant succession begins to reestablish native and nonnative plants. Insects and weeds, however, play a role in the ecosystem. Many people hurry to pull, hoe, or spray every weed they see. It can be tempting to look for a quick solution to an insect feeding on a garden plant. Pests in a garden or landscape may include insects and mites, weeds, plant diseases, mammals, and birds. Pests as Part of a Natural System Skip to Pests as Part of a Natural System
