| 摘 要： | 用稻茎浸渍法测定了广西不同白背飞虱种群对4种杀虫剂的敏感性。结果表明，不同白背飞虱种群对噻虫嗪的敏感性最高，LC50值在0．0526-0．3161mga.i./L之间；对吡虫啉也有较高的敏感性，LC50在0．0932-0．7646mga．i．／L之间；对噻嗪酮和氟虫腈的敏感性相对较低，LC50值在0．1951-2．7259mga．i．／L之间。不同白背飞虱种群对同一种杀虫剂的敏感性差异很大，对氟虫腈和吡虫啉的敏感性差异超过8倍，对噻嗪酮和噻虫嗪的敏感性差异达5～6倍。

| Abstract: | The susceptibility of Sogatella furcifera populations collected from different areas of Guangxi to four insecticides were monitored by rice-stem dipping method. The result showed that different populations of Sogatella furcifera had the highest susceptibility to thiamethoxam for which the LC50 ranged from 0.0526 to 0.3161mg a.i./L. Different populations had higher susceptibility to imidacloprid for which the LC50 ranged from 0.0932 to 0.7646 mg a.i./L. However, they had lower susceptibility to buprofezin an... |
