褐飞虱Nilaparvata lugens(Stl)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(rm)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。
Nilaparvata lugens (Stl), a worldwide pest of rice, is one of the major measures to control BPH. In order to screen out rice varieties resistant to BPH and suitable for planting Huang-Huai River basin in China, under the condition of temperature of 26 ± 1 ℃, RH of (85 ± 5)% and L: D = 16: 8, The main rice cultivars were used as foodstuffs and the life table method was used to systematically study the effects of different rice cultivars on the growth, survival and reproduction of the BPH experimental population. There were significant differences in the oviposition, hatchability, adult longevity, egg developmental stages, nymph developmental stages and adult developmental stages of the brown planthopper in rice varieties, and had some effects on the wing-type differentiation of N. lugens. The comprehensive evaluation of life table parameters showed that the intrinsic rate of increase (rm) of brown planthopper was 0.56, the net increment rate (R0) and population trend index (I) of Qingliangyou 916 were higher, reaching 163.50 and 191.02, respectively, followed by Fengfeng 2053, Gangyou 5330, Ⅱyou 688, Ⅱ You 2035, Xiangfeng 1026, Fengliangyou 916, Fengnou 801 and pearl waxy, which showed that Liangyou 916 was the most suitable for the growth and reproduction of BPH.
