皱鞘双条杉天牛(Semanotus bifasciatus Sinoauster Gressitt)是为害杉木的一种毁灭性蛀干害虫。杉木严重被害后导致风折、枯死,损失巨大,是目前林业生产上急待解决的问题。1978年我所把皱鞘双条杉天牛列入研究课题,在南靖县林场半山工区设立研究基点,通过三年多来试验,基本上摸清该虫生活史、生活习性及发生发展规律,在此基础上探讨营林技术措施、化学药剂和生物防治途径,从而找出一些行之有效的防治方法。现将试验研究情况综合整理如下:
Semanotus bifasciatus Sinoauster Gressitt is a devastating stem borer for Chinese fir. After the serious damage of Chinese fir, it causes the wind breakage, the withering death and the huge loss, which is the urgent problem to be solved in the forestry production. In 1978, we included the crucuminum double-canelitazone into the research project, set up a research base in the Mid-mountain Work Area of the Forest Farm in Nanjing County, and through more than three years of experiments, basically obtained a clear understanding of the life history, habits, and laws of occurrence , On this basis, to explore the technical measures of forest management, chemical agents and biological control ways to find out some effective prevention and treatment methods. The experimental study is now consolidated as follows:
