浙江衢州毛竹林低改后害虫种群变动分析

自20世纪80年代始，衢州市各县(市、区)逐渐推广毛竹低产林改造技术，为竹林增产增效打下了基础。但是，由于改制后的毛竹林地被挖锄，天敌资源锐减，竹林中年年有笋，立竹上终年披叶，使竹子害虫食物条件改善，致使竹子害虫种类、数量增加，危害逐年加重。通过害虫种群变动分析，可以为开展竹林病虫害综合防治提供有效的应对措施。

Analysis on Insect Species in Low-Yield Moso Forest in Quzhou, Zhejing after Transformation

Since 80s, transformation technology of low-yield Moso forests has been carried out in Quzhou city, Zhejiang province, it made a base for output increasing. But, after the transformation, Moso forests were dug, the resources of natural enemies reduced.Bamboo shoot grows every year, and leaves cover all the year round, the condition of insect edibles improved, therefore, the insect variety increased and its damage becomes more serious. The efficiency measures should be provided for carrying out integrated pest control in Moso forest by insect dynamics analysis.
