临海县连畔公社农科站,采取有效措施,保护稻田蜘蛛,走农业生产良性循环的道路。稻田蜘蛛是水稻褐飞虱、灰飞虱、黑尾叶蝉及纵卷叶螟低龄幼虫捕捉性的天敌。早在一九七九年,这个公社农科站的副站长金崇梅就对这方面进行了反复的调查研究,发现稻田蜘蛛的多少决定(虫向)虫密度高低,如果早稻田蜘蛛与(虫向)虫比例是1:10,晚稻田蜘蛛与(虫向)虫比为1:16,可以不用农药防治,也可以获得粮食增产,而且可以减少农药残留
Linhai County Lianbian commune Agricultural Station, take effective measures to protect rice spiders, take the road to a virtuous circle of agricultural production. Paddy spiders are the natural enemies of the brown rice planthopper, Laodelphax striatellus, Nephotettix cincticeps, and the young larvae of the rice leafroller.

If the Waseda spiders and ) Worm ratio is 1:10, the late rice field spider and (insect) worm ratio of 1:16, you can not pesticide control, you can also get grain yield, but also reduce pesticide residues
