The virulence characteristics of brown planthopper, Nilaparvata lugens Stal, from paddy field population andgreenhouse population collected in late rice field last year was compared. The results showed that those two populations couldinfest successfully the resistant rice variety IR26 bearing resistant gene Bph1, implying the characters of biotype 2. No significant differences in nymphal feeding preference, survival rate and duration among feeding the various resistant rice varietiesTNI, IR26, and ASD7 were found.
