| 摘 要： | 本试验选用22.4%螺虫乙酯悬浮剂(Spirotetrama)、TTP200SC、倍内威(溴氰虫酰胺10%OD)3种新型杀虫剂,对番茄地烟粉虱进行了田间药效试验,结果表明:7个施药处理在药后1～7天药效持续增强,7～21天药效逐渐减弱,药效持续期可达21天。TTP+螺虫乙酯,每公顷用量为199.5 mL+417 mL时,在药后1、3、7、14、21天,5个时间段都是效果最好的处理,当该处理施药7天时综合防效达到最好,若虫和成虫虫口防效都极显著高于其他处理,此时烟粉虱若虫虫口防效为93.06%、成虫虫口防效为92.19%。该施药处理对烟粉虱的综合防效及持效期防效最佳。

| Abstract: | We selected three kinds of insecticides, which were 22.4% Spirotetrama suspending agent, TTP200SC and Betwifruit (10% OD), and studied their effect on Bemisia Tabaci in tomato. The results showed that the drug effect increased in the first 1 to 7 days after application, and gradually decreased from 7 to 21 days, the drug effect could last for 21 days. When TTP + Spirotetrama were used as 199.5 mL + 417 mL, the drug effect was good after application for 1, 3, 7, 14 and 21 days, and the comprehensive control effect reached the best 7 days after the application, the effective rate was 93.06% and 92.19% for nymph and adult worm. The treatment has the best control effect and lasting effect on Bemisia Tabaci. |
