早竹造瘿害虫生态调控技术研发和效果评价

生态调控作为害虫管理的“高级”策略，具有广阔的应用前景。文章依据生态调控的基本原理，研发了植物源诱控技术、功能植物紫云英的利用技术、人工摘瘿和挂瘿防虫技术、早竹抚育时自然天敌保留4项关键技术，对造瘿害虫进行生态调控。生态调控效果评价表明，2018年、2019年和2020年的竹林有虫株率降低率分别为1.79%、2.13%和8.97%，而2019年和2020年的校正虫口减退率分别为31.78%和20.65%，生态调控效果明显。

Development and Effect Evaluation of Ecological Regulation Techniques for Gall-inducing Pests of Phyllostachys violascents

As an“advanced”strategy of pest management,ecological regulation and management has an extensive application prospect.Based on the basic principles of ecological regulation and management,the study integrated four key technologies,including plant volatiles-based attract-and-kill technology,utilization of functional plant milk vetch,artificial gall removing and hanging gall to release natural enemies,and retaining of natural enemies in tending of Phyllostachys violascents forest.The results showed that in 2018,2019 and 2020,the reduction rates of infestation were 1.79%,2.13%and 8.97%,respectively,while the adjusted mortality of gall-inducing pests in 2019 and 2020 were 31.78%and 20.65%,respectively,which indicated the obvious effect of ecological regulation and management.
