摘要
近年来,阿拉善左旗防沙治沙区的植物大面积发生灰斑古毒蛾虫害,严重制约其防风固沙效能的正常发挥.为寻求安全、环保、有效的防虫害药剂,文章通过室内3％甲氨基阿维菌素药剂、5％桉油精、1.0％苦参碱可溶液剂、26％阿维·灭幼脲悬浮剂四种药剂不同浓度和林间同一浓度对灰斑古毒蛾幼虫进行毒力测定试验,筛选出适合于当地、安全且防治效果较好的生物制剂为1 500倍液5％桉油精,为今后大面积防控灰斑古毒蛾虫害提供一定参考.
Abstract
In recent years,the plants in the sand control area of Alashan Left Banner have been severely affected by the infestation of Orgyia Ericae,which greatly restricts the normal function of windbreak and sand fixation.In order to find a safe,environmentally friendly,and effective insecticide,this paper conducted toxicity tests on the larvae of Orgyia Ericae with different concentrations of four agents,namely 3％abamectin,5％eucalyptus oil,1.0％matrine soluble liquid,and 26％abamectin and azinphosmethyl suspension in the laboratory,and the same concentration in the forest.The most suitable,safe,and effective biological agent selected for local use is 5％eucalyptus oil at 1 500 times dilution,providing a reference for the large-scale control of Orgyia Ericae infestation in the future.
