摘　　要：为阻止榆紫叶甲(Ambrostoma quadriimpressum)及落叶松毛虫(Dendrolimus superans)上树为害,在树干上安装阻隔器对其进行防治试验,采用粘胶涂干法检验阻隔效果和设立对照,并与塑料环阻隔法进行防治效果比较。结果表明:在榆紫叶甲防治试验中,开口向上的阻隔器阻隔率为63.44%,开口向下的3组阻隔器的阻隔率均在90%左右,其中黑色阻隔器的阻隔效果优于红色和绿色,阻隔率高达99.46%;而塑料环的阻隔率仅为32.26%;粘胶环上除了目标昆虫外,还粘有其他种类的节肢动物,数量是目标害虫的2.2倍,其中蜘蛛、寄蝇和蚂蚁的个体数量占总数的86.83%。在松毛虫防治试验中,阻隔器的阻隔率为100%,塑料环的阻隔率为88.46%。对于这2种害虫,树干阻隔器的阻隔效果最好,并且对树木生长和生境内的其他种群没有影响,是最佳的阻隔上树防治方法。A control experiment was conducted to prevent Ambrostoma quadriimpressum and Dendrolimus superans from climbing up the trees by using trunk barrier,coating with sticky glue ring to examine the blocking effect and set up the control.The control effect of trunk barrier was compared with trunk coating with smooth tape.In the control test of Ambrostoma quadriimpressum,the blocking efficiency by trunk barrier opening upward was 63.44%,and around 90%for the three groups of trunk barrier opening faced downward.The blocking efficiency of black barrier was as high as 99.46%,higher than that of red and green ones.Meanwhile,the blocking efficiency of smooth tape only was 32.26%.The various arthropods amounted 2.2 times as many as the target pest were pasted to the sticky glue rings,in which the spiders,tachinids and ants account for 86.83%of the total.In the control test of Dendrolimus superans,the blocking efficiency of barrier devise was 100%,whereas,the blocking efficiency of smooth tape was 88.46%.For these two pests,the trunk barrier is optimum blocking method because it has best blocking effect and has no influence on growth of tree and other species in the ecosystem.
