| 中文摘要: |
| 采用稻茎浸渍法测定了18种杀虫剂对褐飞虱的毒力, 选活性较好的药剂进行复配, 筛选出具有较高活性的混剂, 测定不同类型增效剂的增效作用与复合增效作用, 并研究混剂与复合增效剂的最佳增效配伍。结果表明, 18种药剂对褐飞虱的毒力大小次序为：氟虫腈>噻嗪酮>烯啶虫胺>氟铃脲>噻虫嗪>甲维盐>吡蚜酮>阿维菌素>丁醚脲>毒死蜱>速灭威>啶虫脒>异丙威>联苯菊酯>吡虫啉>高效氯氟氰菊酯>三唑磷>马拉硫磷, 其中氟虫腈的活性最高, 是吡虫啉的128.38倍。不同药剂复配中, 烯啶虫胺与噻嗪酮(30∶70)复配的共毒系数最高, 为246.02。6种增效剂与药剂混配增效作用, 以氮酮、有机硅最好, 增效比在2.69~2.85之间, 并且将两者按40∶60配比后, 其联合增效作用有显著提高。 |
| 英文摘要: |
| Rice stem dipping method was used to test toxicity of 18 insecticides against Nilaparvata lugens(St?l). The screened pesticides with high activity were compounded to test joint toxicity and synergies against N.lugens, and determine the synergistic activity of different synergists with screened compound. The results showed that the order of the toxicity was: fipronil> buprofezin> nitenpyram> hexaflumuron> thiamethoxam> emamectin benzoate> pymetrozine> abamectin> diafenthiuron> chlorpyrifos> metolcarb> acetamiprid> isoprocarb> bifenthrin> imidacloprid> lambda-cyhalothrin> triazophos> malathion. Fipronil showed the strongest activity, which was 128.38 times as high as that of imidacloprid. The co-toxicity coefficient of nitenpyram with buprofezin (30∶70) was the highest (246.02). Azone and organic silicon showed the best synergism among 6 synergists with insecticides, with synergistic ratio of 2.69-2.85, and the synergistic effect was significantly improved at the rate of 40∶60. |
