摘要
黄斑星天牛在陕、甘、宁三省(区)已成灾数十年。该虫以危害杨树为主,两年发生1代,是典型的 K 类生态对策昆虫。得出的杨树抗天牛序列,抗虫的理化机制,为营造抗虫生态型林打下了基础。对白僵菌等天敌和化学防治研究结果,为协调应用有效防治技术提供了资料。为生物学、生态学、解剖学、数学模型的研究结果提供了准确预测预报的技术依据。黄斑星天牛的综合防治应以营造抗虫速生生态经济型林为基础,实行多种有效防治手段相协调,以达到有虫而不成灾的目的。
Anoplophora nobilis mainly damages poplars.Its life cycle involves two years,and it is a typical K-strategy insect.The order and physical and chemical mechanism of poplar's resistance to the insect set a base for establishing the insect-resistant ecological stands.Through studies on natural enemies,such as Beauveria bassiana,and chemical control,it will provide useful references for use of effective control techniques.The results from biology,ecology,anatomy and mathematical models lay foundation for accurate prediction.The integrated control of Anoplophora nobilis should take insect-resistant and fast-growing, ecological stands as a basis,with combination of multiple effective control methods.Thus,it will reduce the insect population density,and have minor damage.
