摘　　要：本试验在25℃,不同光周期条件下研究了不同时期白背飞虱和褐飞虱翅型分化情况,初步探明了白背飞虱在中稻后期和晚稻中后期发生数量明显少于褐飞虱,与其翅型的分化密切相关。In the present study,the differentiation of wing dimorphism was investigated under different photoperiods at 25℃.The result revealed that the population density of Sogatella furcifera was obviously lower than that of Nilaparvata lugens in late stage of mid-season rice or in middle to late stage of late rice was closely related to the differentiation of wing dimorphism.

关 键 词：白背飞虱 褐飞虱 长翅型 短翅型
