青岛地区褐梗天牛发生规律研究

为揭示褐梗天牛Arhopalus rusticus(Linnaeus)在青岛地区发生规律,采用林间踏查、设置诱捕器、解析枯死木的方法对青岛李沧地区黑松林内褐梗天牛发生规律及特性进行调查及分析。结果表明褐梗天牛在李沧成虫期为每年4月底5月初至10月上中旬,每年有两个羽化高峰期,分别为6月中旬至8月上旬和8月中旬至9月下旬。实验结果为青岛地区防治褐梗天牛甚至控制松材线虫病蔓延提供了参考依据。

In order to reveal the regularity of Arhopalus rusticus （Linnaeus） in Qingdao, this study adopted the method of step investigation,setting traps and analyzing the dead wood.The results showed that the adult period of A. rust/ctts is at the beginning of May to the middle of October each year. There are two eclosion peaks each year,from mid June to early August and mid August to late September. The experimental results provide a reference for the prevention and control of A. rusticus and even the control of the spread of Pine wilt disease in Qingdao area.
