| 摘 要： | 芽梢斑螟幼虫蛀害马尾松雄花枝、球果和嫩梢,造成果萎、断梢和形成小而密的树冠,是我国马尾松等松类上新发现的重要钻蛀性害虫。该螟在浙江省淳安县为一年一代,以幼虫在被害雄花枝、球果和枯梢上越冬。本文通过系统的观察研究,叙述了该螟发生与林地气候、寄主和天敌等生态因子的关系。通过防治试验,提出灯光诱杀、早春用40％ SN-851等杀虫剂喷梢和保护天敌等治理措施。

| Abstract: | Dioryctria yiai Mutuura et Munroe is a serious forest pest that damages staminate branch, cone and shoot of Pinus massoniana in China. The studies on the biology and control of this insect pest were carried out in Chunan County, Zhejiang Province in 1987~1990. D. yiai completes one generation a year with overwintering as larva in damaged staminate branch, cone and shoot. The paper describes the ecological relationships among the occurrence of the insect and forest climate, host and natural enemy. Experimental results showed that blacklight trap, spraying with the insecticides of SN-851 and 8302 in early spring were effective. |
