十多年来国内对稻飞虱综合治理所采取的措施,有的是以农业防治和化学防治为主;有的主要以保护利用稻田蜘蛛等方法来控制稻飞虱的发生。我们在研究稻飞虱卵寄生蜂缨小蜂的基础上,对福建稻飞虱各虫期的天敌总体进行了初步调查(1977——1982年),得93种。其中缨小蜂、黑肩绿盲蝽、尖钩宽黾蝽和蜘蛛类在稻田数量大,自然控制效能高;瓢虫、隐翅虫也颇常见;螯蜂、撚翅虫和线虫有时局部多发,但通常寄生率较低。1980——1982年我们在福建的沙县和福州调查分析了飞虱与天敌间的数量消长关系,和天敌的自然控制作用。
For more than a decade, the measures taken to comprehensively control planthoppers in our country are based on agricultural control and chemical control. Some of them mainly control the occurrence of planthoppers by protecting and using rice field spiders. Based on the study of the rice planthopper egg parasitic Oncomelania hupensis, we conducted a preliminary survey of natural enemies at each stage of the rice planthopper in Fujian (1977-1982), and obtained 93 species. Among them, the small bees, black-shouldered green bugs, broad-tailed bugs and spiders in the paddy fields of large numbers, high natural control efficiency; ladybugs, pest flies are also common; , But usually lower parasitism. 1980-1982 We investigated the quantitative relationship between planthoppers and natural enemies, and the natural control of natural enemies in Shaxian County and Fuzhou County in Fujian Province.
