摘　　要：本研究利用水、乙醇、丙酮和乙酸乙酯制备了4种天然植物(荨麻、紫草、细香葱和蓍草)的提取物,通过毒力测定和田间药效试验,研究了这几种天然植物提取物对月季蚜虫防治效果。实验结果表明:1) 荨麻和细香葱的水提取物对月季蚜虫有较好的毒杀效果。2) 荨麻水提取物的10 mg/ml稀释液、细香葱水提取物的5.0 mg/ml和10 mg/ml稀释液防治效果较好,校正防效在药后72 h内均达到了80%以上。*通讯作者。This study prepared extracts of four natural plants (nettle, chrysanthemum, fine garlic, and yarrow) using water, ethanol, acetone, and ethyl acetate, and studied the control effects of these natural plant extracts on rose aphids through toxicity tests and field efficacy trials. The results showed that: 1) Water extracts of nettle and fine garlic had good toxic effects on rose aphids. 2) The 10 mg/ml diluted solution of nettle water extract and the 5.0 mg/ml and 10 mg/ml diluted solutions of fine garlic water extract had good control effects, with the corrected control efficacy reaching 80% or more within 72 hours after treatment.
