[目的]筛选防治蒙古栎害虫柞褐叶螟最有效的药剂和最经济用药量。[方法]选用3种生物杀虫剂进行蒙古栎柞褐叶螟的防治试验,比较不同药剂和不同剂量的防控效果。[结果]3种生物药剂均能在一定程度上控制蒙古栎柞褐叶螟的为害,但不同药剂不同剂量间杀虫效果存在差别。[结论]1.8%阿维菌素EC起效快、持效期长,是蒙古栎林害虫大面积发生时的首选药剂;8000IU苏云金杆菌起效慢,但有很好的防控效果;25%灭幼脲SC防效较差。
[Objective] The aim was to screen out the most effective medicaments and the most economical dosage for the prevention and control of Quercus mongolica brown oak leaf miner. [Method] Three kinds of biological insecticides were used to control the brown oak mulberry, Mongolian oak, to compare the different agents and different doses of the control effect. [Result] All three kinds of biological agents could control the damage of Mongolian oak mulberry brown leaf miner to some extent, but there were differences between different doses of different pesticides. [Conclusion] The 1.8% abamectin EC has the rapid onset and long-lasting effect. It is the first choice for large-area pests of Quercus mongolica. The 8000IU Bacillus thuringiensis has slow onset but good control effect. The 25% Chlorbenzuron SC is less effective.
