摘要
黄脊竹蝗(Ceracris kiangsu Tsai)是我国竹产区的主要食叶害虫。前人在黄脊竹蝗的形态特征、生物学特性以及防治等方面都作了大量研究。但至今尚没有一个系统的防治指标可指导防治该虫的工作。为了提高防治效果,1986～1991年,着重对与防治指标有关的竹蝗食叶量与危害叶量、一般毛竹林分株均叶面积、竹林受害后对新生竹的影响。
Through measurement of the leaf quantity damaged by Ceracris ktangsu and leaf area of Phyllostachys pubecens stand in Taojian County, Hunan Province, and measurement of culms quantity on the sample plots damaged by C. ktangsu and calculation of the controlling costs and value of the young culms on the sample plots, the economic thresholds for the eggs, nymphs, adults of C. ktangsu have been ascertained. After practice, a series of technical measures have been put forward for the control.
