害虫生物防治综合效益评价方法

害虫生物防治效果的评价方法通常采用化学防治效果的计算方法，一般仅体现短期内对目标害虫的致死作用结果，而忽略了天敌在自然界数量增殖后对害虫种群数量的长期而持续的控制效果，以及在保护生态环境、保护生物多样性等方面的评价。判断害虫生物防治计划是否获得成功，目前缺乏广泛认同的评价方法。本文对害虫生物防治效果的评价方法进行了梳理，并分析了各种方法可用于害虫生物防治效果评价的可行性及其优缺点。在此基础上，利用层次分析法建立了一套评价害虫生物防治综合效益的指标体系，并应用此方法结合国内外害虫防治包括生物防治的案例进行了比较分析，初步提出了害虫生物防治项目成功与否的评价方法和标准。

Method for Evaluating the Comprehensive Benefits of Biological Control of Insect Pests

The effects of biological control of insect pests are usually evaluated using the same methods as those for chemical control.However,the methods focus mainly on the short-term lethal efficacy on the target pests,while neglect the long-term and sustainable control effects along with the increase of natural enemy populations is neglected,and the benefits of biological control in protecting environment and biodiversity either.At present,there is a lack of widely accepted method for evaluating the success of biological pest control programs.In this article,the methods for evaluating biological control of insect pests are summarized,and their practical feasibility and advantages and disadvantages are analyzed.Based on these analyses,an index system for evaluation of biological control was established through the analytic hierarchy process.The index system was comparatively applied in some cases of insect pest control,the methodology and criteria were proposed for evaluating the success of biological control programs.
