稻田蜘蛛是稻田捕食性天敌中的一个重要类群。湖南、江苏、浙江等省对稻田蜘蛛种类做了大量的调查工作,而且对其生物学特性和保护利用进行了一些研究。据湖南研究证实,稻田蜘蛛捕食量大,不仅对稻飞虱、叶蝉有较好的控制作用,微蛛科对低龄纵卷叶虫也有很好的控制效果,为害虫的生物防治增添了新的内容。为了摸清铜仁地区稻田蜘蛛的种类、发生数量及其优势种,为保护和利用稻田蜘蛛提供依据,1979年8~10月害虫天敌资源普查队分别对玉屏、印江、思南三县的部分中、晚稻田进行了调查。现将调查结果整理于后:
Paddy spiders are an important group of predatory enemies in paddy fields. Hunan, Jiangsu, Zhejiang and other provinces have done a great deal of investigation on the spider species in paddy fields, and have done some researches on their biological characteristics and protection and utilization. According to Hunan studies, the predatory amount of rice spiders is large, which not only controls the planthoppers and the leafhoppers well, but also provides good control effects on the young ones and provides new biological control for pests Content. In order to find out the types, occurrences and dominant species of rice spiders in Tongren area, in order to provide the basis for the protection and utilization of rice spiders, from December to October 1979, the census of natural enemies of pests, Middle and late rice fields were investigated. After finishing the survey results:
