| 摘 要： | 分别在室内、室外条件下从光照、虫口密度及不同抗性水稻品种对褐飞虱翅型分化影响进行了研究.结果表明,室内条件下,在短光照、密度为20头/株以下时,雌虫褐飞虱短翅率在87.22%以上,利于短翅型雌虫褐飞虱形成;在长光照、密度在10头/株以上时,雌虫褐飞虱短翅率在46.67%以下,利于长翅型雌虫褐飞虱形成.室外条件下,不同抗性水稻品种对褐飞虱翅型分化影响不一样,感虫水稻品种上短翅型雌虫褐飞虱比例较高.同时无论在什么情况下雄虫褐飞虱的短翅率都不是很高,即外界环境条件对雄虫褐飞虱翅型分化影响不明显.

| Abstract: | Effects of different illumination,density and rice varieties on wing dimorphism of the brown planthopper(BPH,Nilaparvata lugens) were studied in this paper,the results showed that in the room environment,short illumination and the density of BPH was below 20,the percentage of brachypterous female was over 87.22%,fitting for the formation of brachypterous. In the long illumination and the density of BPH was over 10,the percentage of brachypterous female was below 46.67%,fitting for the formation of macropter... |
