| 为筛选防治扶桑绵粉蚧的理想药剂及减少药剂对天敌的影响，本文采用浸渍法测定了5 种药剂对扶桑绵粉
蚧雌成虫的药效试验及对班氏跳小蜂的影响，结果表明，药剂对扶桑绵粉蚧雌成虫的致死作用与浓度成正比，即
浓度越高杀虫效果越好。5 种药剂中，吡虫啉与高效氯氰菊酯防治扶桑绵粉蚧速效、效果好，能较好地控制扶桑绵
粉蚧的危害; 而印楝素和阿维菌素药效持续性明显好于化学药剂。班氏跳小蜂对在此基础上筛选出的10% 吡虫啉
与0. 3%印楝素具有更高的敏感性，24 h 对吡虫啉的LC50
为17. 80mg /L; 对印楝素的LC50
为17. 80mg /L。吡虫啉、
印楝素均作为防治扶桑绵粉蚧的备选药剂，并推荐印楝素可作为扶桑绵粉蚧绿色防治的首选药剂。 |
| 英文摘要: |
| For screening ideal insecticides for control of P. solenopsis and reduce the influence of medicament on natural enemies，toxicities of various pesticides commonly to P. solenopsis female adults and influence on its natural enemies were determined with leaf dipping method. The results showed that the lethal effect of five kinds of pesticides on the female adults of P. solenopsis was proportional to pesticide concentration，namely，when the concentration was higher，the effect was better. Imidacloprid and λ-Cyhalothrin had much better effect than the others，avilable to P. Solenopsis and had better controlled its harm; The effect of Azadirachtin and Avermectin were longer-lasting than other three pesticides and efficacy continued in chemicals. Based on screening of 10% Imidacloprid and 0.3% Azadirachtin，Aenasius bambawalei Hayat had higher sensitivity to the pesticides，24 h，LC50 of imidacloprid for 17.80mg /L; LC50 of azadirachtin for 17.80mg /L. Therefore，Imidacloprid and Azadirachtin could be referenced pesticides in P. solenopsis control，and Azadirachtin should be the first choice. |
