Topic 1: Forest Pest Control

Background Information

Knowledge of topics such as entomology, plant pathology, forest entomology, ecology, etc. are required in order to successfully manage and control forest pests. Forest entomology and pathology are the foundation of forest pest control which is based on ecological theory, ecological health principles, advanced biological pest management tools and control technologies and strategies, scientific pest control, and maintenance of ecosystem health.

A major theme in the World Environment and Development Conference in 1992 is to keep the health and integrity of global ecosystem. A healthy forest ecosystem is always stable and sustainable and can maintain its organized structure and autonomies. It also maintains resilience which includes the resistance to pests and recovery ability after being damaged and disturbed.

In the long history of humanity’s attempts at pest management, management theory by the “struggle” has gradually transformed into “scientific management”. Management strategy has gradually transformed from “simple pest control” to “integrated control” to “comprehensive management”. Recently, Liang and Zhang (2005) also put forward a new strategy of forest pest control, named “ecological control of forest pest (ECFP)”. The ECFP is aimed at maintaining the whole function of forest ecosystem. ECFP mainly includes biological control, cultivation of resistant species, site preparation, as well as dynamic monitoring of pests. The combination of these practices can help restrict the growth and development of pests and reach the goal of ecosystem equilibrium. The usage of chemical fertilizer and insecticides should be reduced or replaced by other control measures. There are also some stages in the process including analyzing, integrating, optimizing, designing and implementing the above mentioned practices, etc. The final goal is to make full use of all kinds of beneficial functions of various bio-resources in the system.
