黄斑星天牛是我省杨树的主要蛀干性害虫之一,目前已在我省天水、平凉等地区的二十多个县市扩散成灾达十余年之久。自1972年以来,已有不少单位相继开始对该虫进行了研究。在防治方面,以往多用人工捕捉成虫,砸卵,药泥堵孔或药液注孔等措施,但由于比较费工费时,常常不能收到预期的效果。因此为应生产上的急需,进一步探索大面积防治技 Asteroidus is one of the main stem borers of Poplar in our province. It has been spread in more than 20 counties and cities in Tianshui, Pingliang and other areas of our province for more than ten years now. Since 1972, many units have started to study this pest. In terms of prevention and control, in the past many measures such as artificial capture of adult worms, egg smashing, blocking of medicinal mud or injection of liquid medicine have been used. However, due to the time-consuming work, workers often can not receive the expected results. Therefore, in order to urgently need production, we should further explore large-scale prevention and control technologies
