摘 要:通过对紫金山不同森林植被类型鳞翅目昆虫种类、种群密度、分布及发生规律的调查,综合了优势种类、本地区历史危害种类、省级历史危害种类,运用有害生物多指标综合评估分析方法,从害虫分布区域、危害程度、受害植物经济重要性、生物生态学特性、防控难度与天敌作用等6个方面16个风险因子对上述可能造成危害的各类鳞翅目害虫进行了危险性分析,确定了4个等级共52种害虫,其中需重点防控的有6种,需密切关注的有10种。Lepidoptera species for different vegetation types,its population density,distribution and occurrence at Zijinshan Mountain area were investigated.According to integrated information of dominant species,the history of the region endanger species and Jiangsu province,the method of multi-criteria evaluation of pests was used to do the risk analysis.Six fields with 16 risk factors,i.e.,the distribution area of pest,harmful levels,the economic importance of endangered plants,biological characteristics,ecological characteristics,the difficulty of prevention and control and effects of natural enemies were considered in the risk analysis.The analysis results showed that all kinds of Lepidoptera pests were harmful.Four levels of 52 species of insects were identified.Among these insects,six species of them need to be prevented and controlled significantly,and 10 of them needs to be paid more attention.
