[Objectives]  To determine the resistance of the Guiyu No.11 rice variety, a high-yield, high-quality variety with efficient nitrogen utilization that is widely planted in Guangxi, to the brown planthopper (Nilaparvata lugens, BPH) and the effect of feeding on this variety on BPH population growth. [Methods] The amount of honey-dew secreted, nymph survival rate, population trend index, relative developmental fitness, and other BPH population indices were measured on three different rice varieties with varying degrees of resistance to the BPH; Guiyu No.11 (moderate resistance), Rathu heenati (resistant) and Liuhsayouzhan 202 (susceptible). Life tables were then used to compare the effects of feeding on each rice variety on BPH feeding, growth, development, survival and reproduction. [Results]  There was no significant difference in the amount of honeydew secreted (7.82 mg/ 24 h), nymph survival rate (74.00% young nymphs, 90.64% older nymphs), female: male sex ratio (46.22%), proportion of brachypterous individuals (80.77%), adult female longevity (14.9 d), adult female body weight (1.71 mg) or egg capsules per female (524.10 capsules), between BPH that fed on Guiyu No.11 and those that fed on Liushayouzhan 202 (P>0.05), but the eclosion rate (61.00%) and egg hatchability rate (76.86%) of those that that fed on Guiyu No.11 were significantly lower than that of those that fed on Liushayouzhan 202 (P<0.05). The amount of honeydew secreted, nymph survival rate, eclosion rate, adult longevity, female body weight, oviposition and hatchability of BPH that fed on Guiyu No.11 were all significantly higher than those that fed on Rathu heenati (P<0.05). Only the duration of the nymph period (15.52 d) was significantly lower on Guiyu No.11 than on Rathu heenati (P<0.05). The population trend indices for Liushayouzhan 202, Guiyu No.11 and Rathu heenati were 84.97, 61.52 and 0.00, respectively, and relative developmental fitness on Guiyu No.11 and Rathu heenati were 0.72 and 0.00, respectively. [Conclusion]  Guiyu No.11 is moderately resistant to the BPH under current conventional nitrogen application conditions in Guangxi. Compared to the susceptible variety Liushayouzhan 202, the development of the BPH is significantly lower on Guiyu No.11, which may slow the population growth of this pest in the field.
