黄脊竹蝗(Ceracris kiangsu Tsai)是毛竹林的主要害虫,我国南方毛竹产区常遭大面积危害,严重影响毛竹的生产。过去对此虫的生物学、发生规律及防治方法等曾有人作了不少研究,但对防治指标尚未进行研究,常有盲目进行防治的现象。我们自1987年起开展了这项工作。一、调查结果及分析 (一) 不同眉径及不同龄级的毛竹叶片蓄积量(见表1、图1) Ceracris kiangsu Tsai is a major pest of Moso bamboo forests. Moso bamboo production areas in southern China are often endangered by a large area and seriously affect the production of Moso bamboo. In the past, many studies have been done on the biology, the law of occurrence and the methods of prevention and treatment of the insects. However, no research has been done on the prevention and treatment indicators, and the phenomenon of blind prevention and control has often been followed. We have started this work since 1987. First, the survey results and analysis (A) different brow diameter and age classes of bamboo leaf volume (see Table 1, Figure 1)
