毛竹主要食叶害虫研究进展

Research Advances on the Pests That Eat Leaves of Phyllostachys heterocycla cv. pubescens

通过对毛竹主要食叶害虫 (包括害螨 ,下同 )的种类、危害和分布状况的研究 ,并从生物学特性、生态学特性、防治指标及预测预报、综合治理技术和天敌的种类、生物学及生态学等方面综述了近 2 0年来的研究概况 ,在此基础上 ,提出当前研究和实践中存在的问题 ,主要是 :1对害虫大发生的机理研究不够深入 ;2过于注重对主要害虫的研究 ,忽视对次要害虫的研究 ;3对某些主要害虫、天敌的生态学研究得不够全面 ,且缺乏有效的监测系统和害虫控制措施综合评价系统 ;4综合治理过于依赖化学防治 ,在一定程度上忽视了综合性营林措施的根本效益 ,生物防治研究与实践工作力度不大 ;最后 ,针对存在的问题 ,讨论了将要开展的工作。

This paper summarized the results of studies on the pests that eat leaves of Phyllostachys heterocycla cv.pubescens in recent 20 years,which include pest species,demage and distribution in China from the aspects of biological character,ecological character,protective target,forcast,comprehensive technology,natural enemies,biology and ecology.At the same time,it offered some problems existing in research,which were as follows ①Mechanism research on the outbreak of the pests was not deep enough.②Researches on the subordinate pests were neglected.③Research on pests and natural enemies was not comprehensive and effective supervision system and integrated system for evaluation of 2PM were lack.④Comprehensive cure depended too much on chemical pesticide control measures.Biological and forestry technical measures were neglected.In the end,it discussed some future work towards the present problems
