背景技术背景：2003年，在泰国首次发现褐飞虱（Nilaparvata lugens）（同翅目：飞虱科）对类烟碱杀虫剂产生抗药性，此后在越南、中国和日本等其他亚洲国家也发现了这种抗药性。然而，在许多亚洲国家，褐飞虱和白背飞虱（WBPH）对烟碱类杀虫剂和苯基吡唑类杀虫剂的LD 50值报道较少。吡虫啉在东亚地区褐飞虱种群中的局部LD_（50）值（日本、中国、台湾）和越南的含量为4.3-24.2 μ g g（-1），显著高于菲律宾的含量（0.18-0.35 μ g（-1））。种群对吡虫啉和噻虫嗪的交互抗性为正交互抗性。几乎所有的白背飞虱人口从日本，台湾，中国，越南和菲律宾有非常大的LD 50值（19.7-239 μ g g（-1）或以上）的氟虫腈，除了几个人口从菲律宾和中国。结论：物种特异性变化的杀虫剂敏感性被发现在亚洲稻飞虱（即对吡虫啉和白背飞虱氟虫腈）。东亚和中南半岛的褐飞虱对吡虫啉产生了抗药性，但菲律宾没有。相比之下，白背飞虱对氟虫腈的抗药性在东亚和东南亚广泛存在。(c)2008年化学工业协会
BACKGROUND: In 2003 the development of insecticide resistance against neonicotinoids in the brown planthopper (BPH), Nilaparvata lugens (Stal) (Homoptera: Delphacidae), was first observed in Thailand and has since been found in other Asian countries such as Vietnam, China and Japan. However, the LD50 values of BPH and the whitebacked planthopper (WBPH), Sogatella furcifera (Horvath), against both neonicotinoid and phenylpyrazole insecticides have been poorly reported in many Asian countries.RESULTS: The topical LD50 values for imidacloprid in the BPH populations collected from East Asia (Japan, China, Taiwan) and Vietnam in 2006 were 4.3-24.2 mu g g(-1) and were significantly higher than those collected from the Philippines (0.18-0.35 mu g g(-1)). The BPH populations indicated a positive cross-resistance between imidacloprid and thiamethoxam. Almost all the WBPH populations from Japan, Taiwan, China, Vietnam and the Philippines had extremely large LD50 values (19.7-239 mu g g(-1) or more) for fipronil, except for several populations from the Philippines and China.CONCLUSION: Species-specific changes in insecticide susceptibility were found in Asian rice planthoppers (i.e. BPH for imidacloprid and WBPH for fipronil). Insecticide resistance in BPH against imidacloprid occurred in East Asia and Indochina, but not in the Philippines. In contrast, insecticide resistance in WBPH against fipronil occurred widely in East and South-east Asia. (c) 2008 Society of Chemical Industry
