摘 要：
采用环保型胶带防控食叶害虫,不同部位胶带阻隔效果不同,为了便于胶带捆绑、调查及除治,以胸径1.3m干中部位捆绑为宜。环保型胶带防控食叶害虫的最佳有效阻隔宽度为15cm。通过对不同捆绑方式阻隔效果的研究发现,单环光滑阻隔法适用于落叶松毛虫和杨毒蛾,阻隔率分别达99%和96%,双环光滑阻隔法适用于舞毒蛾,阻隔率达82%。单环阻隔法适用于落叶松尺蠖雌成虫、落叶松球蚜、春尺蠖雌成虫,阻隔率分别达100%、96%、100%。双环阻隔法适用于落叶松尺蠖幼虫、落叶松球蚜、春尺蠖幼虫,阻隔率分别达93.6%、96%、90.6%。双环阻隔舞毒蛾效果比单环阻隔效果明显。

摘 要：
When the environment-friendly tape was used to prevent and control defoliators,different taping positions would lead to different effects. The proper position was the middle trunk with 1.3 m DBH as to the convenience of tape binding, investigation and elimination, and the optimum barrier width was 15 cm. The research on the barrier effects of different binding methods found that the monocyclic smooth blocking method was suitable for dendrolimus sibiricus and stilpnotia candida, and the blocking rates were respectively 99% and 96%. Bicyclic smooth blocking method was applicable to gypsymoth, and the blocking rate was 82%. Monocyclic blocking method was suitable for female adults of larch inchworm, adelge laricis, and A. cinerarius larva, and the blocking rate were respectively 93.6%, 96% and 90.6%. As to the gypsymoth,bicyclic blocking had better effects than monocyclic blocking.
