太原市油松小蠹虫及其综合防控技术研究

Study on Pine Bark Beetles in Taiyuan and Their Comprehensive Controls

小蠹虫是一类重要的森林害虫,多为次期性害虫。通过调查,在太原市为害油松的主要种类是松六齿小蠹、松八齿小蠹和松十二齿小蠹;成虫扬飞期分别出现在5月份、7月份、8月份、9月份,是防治的关键时期;引起小蠹虫成灾的原因除自然因素外,主要是人为因素,所以防控小蠹虫要以虫情测报为基础,以检疫和林木管护措施为主导,并辅以生物、人工、化学等综合防控措施。

Pine bark beetles are important forest pests that induce serious harmfulness in later years.In Taiyuan,the species of pine bark beetles include sixdentate bark beetle,eightdentate bark beetle,and twelvedenate bark beetle.Flying period of the adult is in May,July,August and September.The period is the key period of control.Except for natural factors,the reasons of beetle happening are also due to artificial factors.Therefore,the controls of beetles depend on pest forecast,focus on quarantine and protection of forest plant,add biological,artificial,chemical methods.
