| 摘 要： | 为了筛选适于草坪害虫斜纹夜蛾（Prodenia litura）防治的绿色农药，采用浸叶法测定比较了5个不同化学类别共20种绿色杀虫剂对斜纹夜蛾3龄幼虫的室内活性。结果表明，7种常用农用拟除虫菊酯类杀虫剂的杀虫效果不及常规有机磷农药毒死蜱，而2种新型拟除虫菊酯四氟醚菊酯和四氟苯菊酯的杀虫效果相当或优于毒死蜱；苯甲酰脲类药剂虱螨脲、氟啶脲和氟铃脲，双酰肼类虫酰肼，杂环类茚虫威和虫螨腈，以及生物源类杀虫剂甲氨基阿维菌素苯甲酸盐7种药剂对斜纹夜蛾的活性高，均符合绿色无公害农药的基本要求，是值得进一步试验开发用于草坪斜纹夜蛾等夜蛾类害虫防治的候选药剂。

| Abstract: | To screen green pesticides for the management of Prodenia litura, laboratory efficacies of 20 green pesticides belonging to five different chemistries were evaluated on the 3rd instar larvae of P.litura using leaf dip method. Results showed that efficacies of seven pyrethroids (lambda cyhalothrin, cyfluthrin, bifenthrin, beta cypermethrin, cypermethrin, fenvalerate and fenpropathrin) commonly used in agriculture were lower than that of conventional organophosphorus insecticide chlorpyrifos, two novel pyrethroids (transfluthrin and tetramethylfluthrin, mainly used in vector control) had higher or equal activity compared with chlorpyrifos. Lufenuron, chlorfluazuron, hexaflumuron, tebufenozide, indoxacarb, chlorfenapyr and emamectin benzoate were the seven most effective to P.litura in laboratory among twenty tested green pesticides. Belonging to five different modes of action, these seven insecticides can be used as green pesticide candidates for the control of turf insect pest P.litura and served to be further studied in field. |
