Developing and Analysing Pest-natural Enemy Systems with IPM Strategies

摘要

Integrated Pest Management (IPM) is an effective, long term, environmentally sensitive approach to pest management. IPM relies on a combination of biological, cultural, and chemical tactics that reduce pests to tolerable levels by augmenting natural enemies, spraying pesticides, trapping or harvesting the pests when they reach an Economic Threshold (ET, Figure 1). ET is an important concept in IPM which is usually defined as the critical density of pests in the field when control actions must be taken to prevent the economic injury level (EIL, Figure 1) from being reached and exceeded. The EIL is defined as the lowest pest population density that will cause economic damage.
