利用昆虫病原线虫防治钻蛀和隐蔽性害虫是一种有效的生物防治手段 ,也是害虫持续控制研究的方向。室内外试验表明 ,小卷蛾线虫Agriotos品系是防治东北大黑鳃金龟 (Holotrichiadiomphalia)、白星花金龟(Potosiabrevitarsis)和向日葵螟 (Homoeosomaelectellum )理想的生物因子 ,应用前景广阔。而青杨天牛(Saperdapopulnea)虽在室内对其十分敏感 ,但其危害特性却不利于线虫的应用 ,林间防治效果差。因此 ,目标害虫及其危害特性是影响线虫产业化的重要原因之一 The use of entomopathogenic nematode to control borers and hidden pests is an effective means of biological control and also the direction of pest sustained control research. Indoor and outdoor tests showed that the Agriotos strain of Nematodes is an ideal biological factor for controlling Holotrichiadiomphalia, Potosiabrevitarsis and Homoeosomaelectellum, and has wide application prospect. However, although Saperdapopulnea is very sensitive to indoors, the harmful characteristics of Saperdapopulnea are not conducive to the application of nematodes, and the effect of forest control is poor. Therefore, the target pests and their harmful characteristics are one of the important reasons that affect the industrialization of nematodes
