| 摘 要： | 首次报道深褐拟叶螽在山核桃上的危害。2007—2010年,对危害山核桃的深褐拟叶螽进行野外调查并定株观察,同时开展防治试验。深褐拟叶螽严重危害的林分被害率高达100%,被害次年基部以上枝干死亡的林木达95%,被害3年后整株死亡率达到25%,严重影响山核桃幼林生长。通过使用冬季刻杀卵、伐除林缘算盘子,以及在5月中旬、7月中旬各使用1次3%高效氯氰菊酯微囊悬浮剂等措施进行综合防治,当年冬季该虫有虫株率下降为8%,平均每株卵量下降为4.5粒,次年林分基本恢复正常,完全控制该虫危害。

| Abstract: | Based on the field investigation,the experiments of integrated control on Tegra novaehollandiae-viriainotata(Stal) were conducted from 2007 to 2010.The results showed that almost 100% trees were harmed in the severe damaged forest stands.The mortality rate of branches above the base of trees was reached to 95% in the second year,and the mortality rate of the intact trees was up to 25% after three years.The integrated measures such as ovicidal in winter,removal of Glochidion puberum on the edge of stands,and... |
