蜘蛛在农林害虫的捕食性天敌中是一个很重要的类群。农田蜘蛛不仅种类多,而且种群数量大,占田间捕食性天敌数的百分之八十至九十五;同时蜘蛛性情凶猛,行动敏捷,其杀虫量比瓢虫、草蛉、猎蝽等天敌昆虫的杀虫总量还要大得多。在害虫的生物防治中,以蛛治虫是“以虫治虫”的另一有效途径。因此,随着农业资源调查的深入开展,各省区对蜘蛛这一天敌资源的调查工作也给予了足够的重视。
Spiders are a very important group of predatory enemies of agricultural and forestry pests. Spider is not only a wide range of species, but also a large population, accounting for 80% of the field predators of natural enemies; at the same time spiders ferocious, quick action, the insecticide than ladybugs, Natural enemies insect insecticide total even greater. In the biological control of pests, the worm is another effective way to pest control. Therefore, with the in-depth investigation of agricultural resources, all provinces and autonomous regions have given sufficient attention to the investigation of natural enemies of spiders.
