星天牛行为及控制技术研究Ⅱ.星天牛控制技术的研究

在对沿海防护林木麻黄主要蛀干害虫星天牛(Anoplophorachinensis(Forster))行为和发生规律研究的基础上,针对新造林和现有林虫害发生的不同特点,通过林间虫情调查进行预测预报,运用综合控制理论,提出在加强抚育管理的基础上分类施策。新造林应大力推广抗性品系,结合营造木麻黄与湿地松、相思树、桉树等的混交林,幼林阶段适当修枝、保留地被物等营林措施;现有林的星天牛以苦楝树诱杀成虫,人工措施处理初龄幼虫为主,并用白僵菌粘膏等生物防治措施控制危害。综合控制技术在福建沿海部分地区推广应用,推广抗性品系苗木300万株,在试验示范林内实现了有虫不成灾,取得良好的经济、社会和生态效益。

Studies on the Anoplophora chinensisBeheavior and Control Technique Ⅱ.Study on the A.chinensis Control Technique

Based on the studies on the major stem borer Anoplophora chinensis beheavior and occurrence law of Casuarina equisetifolia in Coastal protective forests,this paper conducted the prediction and forecast through the investigations of situations of insects in forests in view of the different occurrence characteristics of insects in newly planted and present forests.Carrying out countermeasures classificatorily was raised on the basis of strengthening tending management with comprehensive control theory.The comprehensive control technique was popularized and applied in Fujian coastal areas.3 millions of resistant strain seedlings were popularized.The insects existed instead of causing the disaster,which was realized in experimental demonstration forests,fine economic,social and ecological kenefits were obtained.
