摘要: 为了筛选控制烟草烟粉虱的有效药剂,采用3种生物杀虫剂对烟草烟粉虱进行室内毒力测定及田间药效试验。室内毒力测定结果表明,对烟草烟粉虱的毒力顺序为:0.5%依维菌素乳油>0.5%藜芦碱可溶液剂>6.0%鱼藤酮微乳剂,其LC50值分别为1.396 mg/L、5.083 mg/L、12.287 mg/L,显著优于对照药剂高效氯氟氰菊酯(LC50值为30.67 mg/L)。田间药效试验结果表明,6.0%鱼藤酮微乳剂、0.5%依维菌素乳油,0.5%藜芦碱可溶液剂稀释2000倍液喷雾处理后,药后3d、7d、14d更正防效对烟草烟粉虱持效性较好,更正防效达70﹪以上。因此,3种生物杀虫剂对烟田未产生药害,烟草植株生长安全,可在生产上进一步推广应用。

Abstract: To screen effective drugs for controlling tobacco Bemisia tabaci, toxicity test and field efficacy of 3 biological insecticides to B.tabaci were used on tobacco. The toxicity test results showed that the virulence of B.tabaci presented as 0.5% ivermectin EC > 0.5% veratridine Solution > 6% rotenone microemulsion, and the LC50 values of them were 1.396 mg/L, 5.083 mg/L, 12.287 mg/L respectively, which was significantly better than the CK cyhalothrin (LC50 = 30.67 mg/L). Results of field efficacy showed that the adjusted efficiency of 3,7,14 days after treatment of 2000 times of dilution of 6% rotenone microemulsion, 0.5% ivermectin EC, 0.5% veratridine solution were over 70%. Therefore, the 3 biological insecticides have no harmful effects on the tobacco field, and the tobacco plants are safe to grow and can be further promoted and applied in production.
