褐飞虱 Nilaparvata lugens(Stal)从迁入开始,以后种群数量激增,在这方面短翅型起了重要的作用。但褐飞虱的迁飞,是依赖长翅型成虫的飞翔。迁飞现象包括几个过程:起飞,飞行,降落,及下降定居之前的短距离飞行。长距离迁飞关于褐飞虱越冬的方式长期存在着争论。在日本褐飞虱无明显休眠状态渡过严冬存活下来。然而,在雨季褐飞虱突然出现于诱灯下或稻田,数量有时很大。目前,褐飞虱的迁飞特 From the beginning of the migration, the population of Nilaparvata lugens (Stal) of Nilaparvata lugens increased rapidly, and the short wing type played an important role in this area. However, the migration of the brown planthopper is dependent on the long-winged adult fly. The phenomenon of migration includes several processes: take-off, flight, landing, and short-range flights before settling down. Long-distance migration There has been long debate over the way in which winter winters are overwintering. Nilaparvata lugens survived the severe winter without significant hibernation. However, during the rainy season, brown planthopper suddenly appeared under light-emitting lamps or in paddy fields, sometimes in large quantities. At present, the brown planthopper moved to fly special
