Studies on hybridization, inheritance, and population genetics of brown planthoppers that infest rice and weeds were undertaken using starch gel electrophoresis to determine whether the weed-infesting population represents a biological race or a species. F(1) and F(2) generations were produced by crosses between parental insects from the two populations with little indication of hybrid sterility. Gpi, Mdh, and Idh loci were inherited in a simple Mendelian fashion in families of two sympatric populations. Sixteen populations of Nilaparvata spp. from eight locations were collected. The Mdh, Idh, Pgm, Gpi, 6Pgd, and Acp loci were polymorphic. The N. lugens of rice with high esterase activity were clustered into a group and characterized by the presence of alleles Gpi (110) and Gpi (120), whereas N. lugens from weeds with low esterase activity were clustered into another group and characterized by Gpi (100) and Gpi (90) . There was a lack of heterozygotes between the common alleles of the two populations. This means that the two groups of individuals belong to different gene pools.
利用淀粉凝胶电泳技术，对为害水稻和杂草的褐飞虱的杂交、遗传和种群遗传学进行了研究，以确定杂草种群是否代表一个生物种或一个生物种。通过来自两个种群的亲代昆虫之间的杂交产生了 F1 和 F2 代，杂种不育的迹象很少。Gpi、Mdh 和 Idh 基因座在两个共生种群的两个家系中以简单的孟德尔方式遗传。从 8 个地点收集了来自 16 个 Nilaparvata spp.种群的样本。Mdh、Idh、Pgm、Gpi、6Pgd 和 Acp 基因座表现出多态性。水稻上具有高酯酶活性的褐飞虱与一个群体聚类，并具有 Gpi（110）和 Gpi（120）等位基因的特征，而来自低酯酶活性杂草的褐飞虱则与另一个群体聚类，并具有 Gpi（100）和 Gpi（90）等位基因的特征。两个种群的常见等位基因之间缺乏杂合子。这意味着这两组个体属于不同的基因库。
