摘 要 ：褐飞虱Nilaparvata lugens (Stål)是世界性水稻害虫,易暴发成灾,选育抗虫品种已成为控制褐飞虱的主要措施之一。为筛选出抗褐飞虱且适合我国黄淮流域种植的水稻品种,在温度为26±1℃、RH为(85±5)%和L∶D=16∶8的条件下,分别以9个河南省主栽水稻品种为食料,用生命表方法系统研究了不同水稻品种对褐飞虱实验种群生长发育、存活和繁殖的影响。褐飞虱在各水稻品种上的产卵量、孵化率、成虫寿命、卵发育历期、若虫发育历期、成虫发育历期等方面均存在显著差异,并且对褐飞虱的翅型分化有一定的影响。生命表参数综合评价表明,青两优916上的褐飞虱内禀增长率(r_m)达0.56,净增值率(R₀)和种群趋势指数(I)较高,分别达163.50和191.02,其次为特丰2053、冈优5330、Ⅱ优688、Ⅱ优2035、香丰1026、丰两优916、丰糯801和珍珠糯,说明青两优916最适合褐飞虱的生长发育和繁殖。

Abstract:Brown planthopper (BPH), Nilaparvata lugens (Stål), is a kind of worldwide serious pests on rice, with easily outbreak. The breeding of resistant variety has become a major management strategy against BPH. To select high BPH-resistant rice varieties in Yellow and Huaihe River areas in China, the systematic study on effect of nine rice varieties in Henan Province on the development, survival and reproduction of BPH was conducted using life table method under laboratory condition with 26±1℃, (85±5)% RH and L∶D=16∶8 photoperiod. The significant differences were found in fecundity, hatching rate, adult longevity, and developmental duration of BPH on different rice varieties. Furthermore, rice varieties to a certain extent had effects on wing dimorphism of BPH. The life table parameters comprehensive analysis revealed that the innate capacity for increase (r_m) of BPH on Qingliangyou 916 (QLY916) was 0.56, the net reproductive rate (R₀) and index of population trend (I) were 163.50 and 191.02, respectively, followed by Tefeng 2053 (TF2053), Gangyou 5330 (GY5330), Ⅱ You 688 (ⅡY688), Ⅱ You 2035 (ⅡY2035), Xiangfeng 1026 (XF1026), Fengliangyou 916 (FLY916), Fengnuo 801 (FN801) and Zhenzhunuo (ZZN). QLY916 was the most suitable variety for growth and development of BPH.
