Abstract： Fipronil is the first commercially used member of the phenylpyrazole i nsecticides that interact antagonistically with GABA-gated chloride channel. Fi p ronil has made a great contribution to manage some of the most destructive crop pests in the world, including species with serious resistance to earlier-used i n secticides. However, with the extensive application in pest control, the great a ttention has been paid to the resistance of insects to fipronil. To date, some s ubstantial agricultural pests such as Plutella xylostella (L.), Bemisia ta baci(Gennadius), Nilaparvata lugens (Stal), Sogatella furcifera (Horv áth), Chilo suppressalis (Walker), Spodoptera litura (Fabricius), etc, have develope d resi stance to fipronil. To provide a theory base for reasonable using fipronil, cur rent status of resistance, cross-resistance, and resistance mechanism were revi ewed in this article.
