摘　　要：【目的】种植抗虫品种水稻是控制褐飞虱Nilaparvata lugens(Stal)发生的有效措施。桂育11号是在广西推广种植的高产、优质的常规稻品种,兼具中抗褐飞虱和氮高效利用特性。本文通过研究褐飞虱在桂育11号上的蜜露分泌量、若虫存活率、种群趋势指数及相对发育适合度等指标,以明确桂育11号对褐飞虱的抗虫性及该品种对褐飞虱种群的控制作用。【方法】采用生命表方法,选择柳沙油占202作为感虫对照品种,Rathu Heenati作为抗虫对照品种,研究不同抗性水稻对褐飞虱实验种群的取食、生长发育、存活和繁殖的影响。【结果】褐飞虱在桂育11号的取食量(7.82 mg/24 h)、若虫存活率(低龄74.00%,高龄90.64%)、雌成虫比率(46.22%)、成虫短翅率(80.77%)、雌成虫寿命(14.9 d)、雌成虫体重(1.71 mg/头)和产卵量(524.1粒/雌)均与在感虫对照品种柳沙油占202的差异不显著(P>0.05),羽化率(61.00%)和卵孵化率(76.86%)显著低于在柳沙油占202的(P<0.05);但取食量、若虫存活率、羽化率、成虫寿命、体重、产卵量和卵孵化率显著高于在抗虫对照品种Rathu Heenati的(P<0.05),仅若虫历期(15.52 d)显著低于在对照品种Rathu Heenati的(P<0.05)。生命表参数综合评价发现,褐飞虱在感虫对照品种柳沙油占202、桂育11号和抗虫对照品种Rathu Heenati的种群趋势指数分别为84.97、61.52和0.00,褐飞虱在桂育11号和对照品种Rathu Heenati的相对发育适合度分别为0.72和0.00。【结论】在广西当前常规施氮条件下,桂育11号对褐飞虱的抗性为耐害性,相对于感虫对照品种柳沙油占202,褐飞虱在桂育11号的发育适合度下降,可能影响其田间种群增长数量。[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 applicati
