The Whitebacked planthopper (WBPH), Sogatella furcifera (Horvarth) originally was k-strategic insect and well-developed into a low r-strategic that caused damage to rice crops. Related to that matter, WBPH control by insecticides sometimes become ineffective on the recommend dose, such situation is suspected that pest had been resistant to insecticides. To response this issues, was carried out the research in the 2014 to evaluate WBPH from West Java province (Karawang, Subang, and Indramayu) of Indonesia against triflumezopyrim, imidacloprid, and cyazypyr. The research used topical application method with probits analysis by POLO-PC. The results showed that the response WBPH from Karawang to imidacloprid tend to susceptible categorywith LD50 was 128.158 ng/g and RRcalculate = 1.25. Response WBPH from Subang and Indramayu to imidacloprid was highly susceptible with LD50 were 78.446 and 76.193 ng/g and RRcalculatewere 0.77 and 0.74-fold respectively. Response WBPH from Karawang, Subang and Indramayu to triflumezopyrim tend to decreased susceptibility category with LD50 were 2.311, 2.152, 1.791 ng/g and RRcalculatewere 2.94, 2.74, 2.28-fold respectively. Response WBPH from Karawang, Subang and Indramayu to cyazypyr tend to decreased susceptibility category with LD50 were 236.149, 194.808, 207.606 ng/g and RRcalculatewere 2.94, 2.42, 2.58-fold respectively. Triflumezopyrim was fantastic insecticide to provide a low LD50 and didn’t induce resistance to WBPH almost of all sites. This insecticides can be used to solve the problem resistance of WBPH against to the other insecticides.
