系统研究了稻田和稻田周围非稻田生境中飞虱、叶蝉和寄生性天敌的种类、分布及其相对丰盛度，并阐明了不同生境间同翅目寄主和天敌的相互关系．稻飞虱和稻叶蝉在非稻田生境中的数量很低，然稻田重要卵寄生蜂Ａｎａｇｒｕｓｓｐｐ．Ｏｌｉｇｏｓｉｔａｓｐｐ．和Ｇｏｎａｔｏｃｅｒｕｓｓｐｐ．在非稻田生境中的平均密度很高．多样性指数低的植被上存在更多的飞虱和叶蝉，同时也保存了许多寄生性天敌．水稻移栽后稻田中节肢动物的数量逐渐上升，至第四周趋于稳定 The species, distribution and relative abundance of planthoppers, leafhoppers and parasitoid natural enemies in non-paddy habitats around paddy fields and paddy fields were systematically studied. The relationship between host and natural enemies of Homoptera was also clarified. The number of planthoppers and rice leafhoppers is very low in non-paddy habitats, but Anagrusspp is an important parasitic wasp in paddy fields. Oligositaspp. And Gonatocerusspp. The average density in non-paddy habitats is high. There are more planthoppers and leafhoppers on the low diversity index vegetation and many parasitic natural enemies. After transplanting rice, the number of arthropods in rice fields gradually increased until the fourth week tended to be stable
