Progress of Forest Insect Pasts Monitoring and Prediction in Foreign Countries

本文从理论基础研究和应用技术观点出发,综述了国际上近10年来森林害虫测报的理论基础、应用基础、空间分布型与抽样调查、种群动态与生命表研制、电脑应用数理统计测报、遥感技术、信息素诱测、雷达监测、灯光诱测等先进技术,并对其发展趋势作出评述。

Prediction of forest pests is a scientific basis of decision making in the integratedforest pest management. Now in forest pest prediction great importance is attached to theapplication of sophisticated science theory and modern technology, such as computertechnology and remote sensing technique. The basic research on forest pest prediction is thetheoretical basis for tentative application of advanced science and technology to forest pestpredictoin, and is the prequisite for establishing a scientific monitoring system. Much workhas been done by experts and scholars both at home and abroad. Researches on the disper-sion pattern and dynamic population of insect pests, revelation of the genetic trais of forestinsects in their outbreaks and making clear the regularity of external ecological environmen-tal influence provide scientific data for the prediction. Sampling survey is a laborious work.Now in foreign countries more scientific methods are employed to make a survey of the in-sect population, which are easy, simple and labor saving. Their examples can be used as ref-erence.
