【摘要】 基于筛选试验结果明确了甲氨基阿维菌素苯甲酸盐、灭幼脲和茚虫威3种对牡丹刺蛾高效的杀虫剂，并对其田间防治效果进行了研究。结果表明，5.7%甲氨基阿维菌素苯甲酸盐水分散粒剂4.5～7.5 g a.i./hm~2、25%灭幼脲悬浮剂112.5～187.5 g a.i./hm~2和15%茚虫威悬浮剂22.5～31.5 g a.i./hm~2防治牡丹刺蛾幼虫效果优良，药后1～7 d，防效分别为78.75%～96.27%、49.69%～98.34%、80.20%～97.42%，对牡丹无药害，对非靶标生物无不良影响。3种杀虫剂可作为牡丹刺蛾防治推荐药剂。更多还原

【Abstract】 Based on the results of screening experiments, three high-efficiency insecticides for eucleid caterpillar of Paeonia suffruticosa, namely emamectin benzoate, chlorobenzuron and indoxacarb, were identified, and their field control effects against eucleid caterpillar of Paeonia suffruticosa in Luoyang were studied. The results showed that the 5.7% emamectin benzoate water dispersible granule 4.5-7.5 g a.i./ha, 25% chlorobenzuron suspension concentrate112.5-187.5 g a.i./ha, and15% indoxacarb suspension concentrate 22.5-31.5 g a.i./ha had excellent control effects on eucleid caterpillar of Paeonia suffruticosa, the control efficacy from one to seven days after treatment were 78.75%-96.27%, 49.69%-98.34% and80.20%-97.42%, respectively. They were safe on Paeonia suffruticosa, and had no adverse effects on non-target organisms.Three insecticides can be recommended as insecticides for the prevention and control of eucleid caterpillar of Paeonia suffruticosa.更多还原
