【摘要】 针对黑龙江省青杨脊虎天牛发生面积大、蔓延快、危害重的现实,对其防治技术进行了研究。结果表明,小叶杨与落叶松混交林被害株率为14%~16%,而小叶杨纯林被害株率则为42%~56%;小青杨与樟子松混交林被害株率为8%,小青杨纯林被害株率为35%~84%。8%的绿色威雷微胶囊剂和3%的氯氰菊酯微胶囊水悬浮剂喷雾防治成虫,效果在75%以上(100液);大力士和氧化乐果树干基部注射防治幼虫,效果达70%以上;10g/m3以上剂量磷化铝片剂熏蒸受害原木,防治效果可达100%。更多还原

【Abstract】 An experiment was conducted to study the control technique for Xylotechus rusticus L., which breaks out on large scale areas in Heilongjiang Province, disperses rapidly and brings serious damages. Results showed that the rates of damaged trees were 14%～16% and 42%～56% in Populus simonii Carr. stands mixed with larch and pure P. simonii stands, respectively, while 8% in P. pseudo-simonii Kitag. stands mixed with Pinus sylvestris var. mongolica Litv., 35%～84% in pure P. pseudo-simonii stands. Both control effects of spraying 100 times solution of 8.0% Luseweilei microcapsules and 3% cypermethrin microcapsules to control the adults were above 75%. Dalishi and omethoate were injected into the base of damaged trees to control larvae, and their control effects were over 70%. While fumigating damaged logs with 10g/m~3 of aluminum phosphide tablets brought a control effect of 100%.更多还原
