结合国内外研究现状,作者通过对飞虱求偶鸣声和种间杂交的比较,阐述褐稻虱的翅型、色型、李氏禾稻虱及其生物型的问题。提出翅型受营养与环境气候影响,是相同基因型的多种表现;色型和李氏禾稻虱则可能具不同基因型;生物型依对不同抗虫基因的水稻品种有不同的反应而定,是否与遗传有关尚有争议。 Combining with the current research situation at home and abroad, the author elaborates on the wing type, color type, L. plantarum and their biotypes of brown planthopper by comparing their mating song and interspecific hybridization. It is suggested that wing-type nutrition and environmental climatic effects are multiple manifestations of the same genotype, while both the color-type and L. plantarum may have different genotypes. The biological type may have different responses to different insect-resistant rice varieties Set, is still controversial with the genetic.
