绿竹两种链蚧的综合防治试验

密竹链蚧、绿竹链蚧是绿竹的主要害虫,为有效防治这两种害虫,选用不同的方法进行防治,研究表明:对危害绿竹的密竹链蚧、绿竹链蚧两种害虫的林间化学防治应以高效氯氰菊酯与敌敌畏、乐果、啶虫脒的混配剂或单一药剂注射防治为好;林业措施防治中,抚育间伐、施肥培土、抚育间伐+施肥培土、人工刮除等4种措施效果都较好,在生产中因地制宜加以组合利用,可有效控制害虫发生;保护、助迁和利用绿竹林中丰富的各种自然天敌进行生物防治,对害虫抑制作用明显。

Integrated Control of Two Bambusaspis Species of Dendrocalamopsis oldhami

Experimental results showed that Dendrocalamopsis oldhami was damaged by two pest species： Bambusaspis miliaris and Bambusaspis notabile, which were controlled by using beta cypermethrin mixed with dichlorvos, dimethoate, acetamiprid together or by individual injection as woodland chemical control methods. Intermediate cutting, fertilization and earthing up, intermediate cutting combined with fertilization and earthing up, as well as artificial curettage were better methods as forestry controlling measures. In forestry production, it could control pest damage effectively to adjust measures to local conditions. The inhibition effects were evident when controlling the pests by biological control methods through protecting, helping migration and exploiting various natural enemies in the plantation ofDendrocalamopsis oldhami.
