Abstract

MIPC-(2-isopropylphenyl-N-methylcarbamate) and MTMC-(3-methylphenyl-N-methylcarbamate) resistant strains of Nilaparvata lugens (Stål) with resistance ratios of 6.1 and 8.0, respectively, were developed in the laboratory by continuous selection for 6 and 7 generations. A survey of the susceptibility to these 2 chemicals confirms the development of resistance in some field populations of this planthopper in Taiwan. The significant correlation observed between the susceptibility to these 2 chemicals in the susceptible and ll-field strains seemed to indicate that there could be cross-resistance between MIPC and MTMC in N. lugens .
