褐稻虱Nilaparvata lugens Stl除为害水稻外,是否还有其它寄主植物,这是多年来褐稻虱研究工作者共同关注的问题。日人持田(Mchida,1977)曾将这方面的研究工作作了综述;国际水稻研究所(1978)就菲律宾的一些禾本科植物和杂草,进行测定;我国有关单位于七十年代也先后进行饲养观察,发表报道。游草Leersia hexandra(Linn.)Swartz是否是褐稻虱的寄主植物,尤为各方面所关注。1980年春季,湖南省农科院雷惠质同志,在全国第四次褐稻虱科研协作会上,又一次作了褐稻虱能以卵在游草上越冬,并能正常繁殖成为本地有效虫源的发言,受到与会者的关注。为了重新了解褐稻虱对游草取食的适应性,我们以游草为食料,一测定褐稻虱成虫在游草上的生殖能力,二考察褐稻虱若虫在游草上的成活率。现将观察结果整理报道,请予批评指正。
Whether Nilaparvata lugens Stl has other host plants besides rice, which is a common concern of brown planthopper researchers over the years, The research work in this field was reviewed by Mchida (1977); the International Rice Research Institute (1978) measured some grasses and weeds in the Philippines; the relevant units in our country were successively carried out in the seventies Feeding observation, published a report. Grasshopper Leersia hexandra (Linn.) Swartz is a host plant of the brown planthopper, especially in all aspects of concern. In the spring of 1980, Comrade Lei Hui-quality from Hunan Provincial Academy of Agricultural Sciences once again made the brown rice louse overwintering in the grassy weeds at the fourth collaboration meeting on brown planthopper research in the country and could reproduce normally The source of the speech, subject to attendees’ attention. In order to understand the adaptability of brown planthopper to grass feeding, we took herbivorous as food material, measured the reproductive capacity of brown planthopper on grass, and investigated the survival rate of brown planthopper nymph on grass. Now the results of finishing reports, please give criticism.
