| 中文摘要: |
| 采用浸叶法在室内测定了3种药剂对苹果黄蚜的毒力, 并在田间进行了防治试验。室内毒力测定结果表明:供试3种新型药剂中, 双丙环虫酯和氟吡呋喃酮对苹果黄蚜的毒力较高, LC50分别为3.16 mg/L和23.58 mg/L, 三氟苯嘧啶毒力较低, LC50为329.92 mg/L。田间试验结果表明:3种药剂对苹果黄蚜均有较好的速效性和持效性。17%氟吡呋喃酮可溶液剂和10%三氟苯嘧啶悬浮剂各处理3～7 d防效为82.19%～93.45%, 药后30 d防效达到78.91%～87.92%;50 g/L双丙环虫酯可分散液剂2.5 mg/kg和4.2 mg/kg处理药后3～7 d防效为94.64%～97.04%, 药后21 d防效仍可达88%以上。因此, 3种新型药剂均可以用于防治苹果黄蚜, 田间使用时推荐有效成分用量为双丙环虫酯2.5～4.2 mg/kg, 氟吡呋喃酮113～170 mg/kg, 三氟苯嘧啶28～80 mg/kg。 |

| In order to evaluate the toxicity and control efficacy of three new insecticides to Aphis citricola van der Goot (Linnaeus), leaf dipping bioassays and field trials were carried out. The results showed that the toxicity of afidopyropen and flupyradifurone to A. citricola was higher, with the LC50 values of 3.16 mg/L and 23.58 mg/L, respectively, while the toxicity of triflumezopyrim was lower, with a LC50 value of 329.92 mg/L. The results of field trials showed that the three insecticides had an excellent quick effect and persistency to A.citricola . The control efficacies of 17% flupyradifurone SL (soluble concentrate) and 10% triflumezopyrim SC (aqueous suspension concentrate) were 82.19%-93.45% 3-7 days post treatment, and 78.91%-87.92% 30 days after treatment, respectively. The control efficacies of 50 g/L afidopyropen DC (dispersible concentrate) at 2.5 and 4.2 mg/kg were 94.64%-97.04% 3-7 days post treatment, respectively, and remained above 88% 21 days after treatment. These results indicate that the three new insecticides can be used to control A. citricola . The recommended application rate should be 2.5-4.2 mg/kg for afidopyropen, 113-170 mg/kg for flupyradifurone, and 28-80 mg/kg for triflumezopyrim. |
