摘　　要：近年来,阿拉善左旗公益林区的白刺(Nitraria tangutorum)灌木林发生大面积白刺萤叶甲(Diorhabda rybakowi)虫害,严重影响其防风固沙效能的正常发挥,其寄生植物锁阳(Cynomorium songaricum)的质量也受到影响。为寻求安全、环保、有效、低成本的防治药剂,采用5%桉油精SL、0.18%阿维·苏云菌WP(森得保)和1.0%苦参碱SL对白刺萤叶甲进行室内、林间防治效果试验。结果表明:1.0%苦参碱SL剂量浓度1∶1 000防治成本最低,室内和林间防治效果均能达到食叶害虫防治要求,且综合效益最高,建议在大面积防治白刺萤叶甲中推广使用。In recent years,the Nitraria tangutorum shrub forests in the public welfare forest areas of Alashan Left Banner have suffered from a large-scale infestation of Diorhabda rybakowi,which has severely affected their sand fixation and windbreak functions,and also impacted the quality of their host plant,Cynomorium songaricum.To find a safe,environmentally friendly,effective,and low-cost control agent,indoor and field trials were conducted using 5%eucalyptus oil SL,0.18%Abamectin and Bacillus thuringiensis WP(Sunderbao),and 1.0%matrine SL against Diorhabda rybakowi.The results showed that the 1.0%matrine SL at a dosage concentration of 1:1000 had the lowest control cost,and both indoor and field control effects met the requirements for leaf-eating pest control,with the highest comprehensive benefit.It is recommended to promote its use in large-scale control of Diorhabda rybakowi.
