| 摘 要： | 用4种生物测定方法测定了7种杀虫剂对越南九龙江褐飞虱种群的毒力。稻茎浸渍法测定结果表明:7种杀虫剂对褐飞虱3龄若虫的毒力(LC50值)大小顺序为氟虫腈>吡蚜酮>噻虫嗪>噻嗪酮>毒死蜱>吡虫啉>叶蝉散;点滴法测定结果表明:5种杀虫剂对褐飞虱雌成虫的毒力(LD50值)大小顺序为噻虫嗪>氟虫腈>吡虫啉>毒死蜱>叶蝉散;浸苗法测定结果表明:7种杀虫剂对褐飞虱3龄若虫的毒力(LC50值)大小顺序为氟虫腈>吡蚜酮>噻虫嗪>噻嗪酮>毒死蜱>叶蝉散>吡虫啉;药膜法测定结果表明:7种杀虫剂对九龙江褐飞虱3龄若虫的毒力(LC50值)大小顺序为氟虫腈>叶蝉散>毒死蜱>噻虫嗪>吡蚜酮>吡虫啉>噻嗪酮。由此可见,目前氟虫腈、噻虫嗪和吡蚜酮药剂对越南九龙江褐飞虱毒力较高,毒死蜱、噻嗪酮毒力次之,吡虫啉和叶蝉散毒力较低,但药膜法测定结果表明,叶蝉散表现出较高毒力,噻嗪酮毒力最小。 |

| Abstract: | The toxicity of seven insecticides to the brown planthoppers of Jiulongjiang,Vietnam was evaluated with four bioassay methods.The orders of toxicity(value of LC50) to the brown planthoppers were fipronil>pymetrozine> thiamethoxam> buprofezin>chlorpyrifos>imidacloprid>isoprocorb with rice stem dipping and pymetrozine>fipronil>imidacloprid>chlorpyrifos>isoprocorb with topical application and fipronil>pymetrozine>thiamethoxam>buprofezin>chlorpyrifos>isoprocorb>imidacloprid with rice seedling dipping and fipronil>isoprocorb>chlorpyrifos>thiamethoxam>pymetrozine>imidacloprid>buprofezin with residual film.In conclusion,the toxicity of fipronil,pymetrozine and thiamethoxam to the brown planthoppers of Jiulongjiang,Vietnam was higher than that of buprofezin and chlorpyrifos,and the toxicity of imidacloprid,isoprocorb was the lowest.Furthermore,the toxicity of isoprocorb was the second highest and the toxicity of buprofezin was the lowest with residual film in seven insecticides. |
