摘要从1959年到1961年，对美国威斯康辛州东北部一个3英亩苹果园的蜘蛛数量进行了自然环境和两个人工环境（captain和DDT）的调查。记录到6科17属24种，其中猎蛛15种，网蛛9种。分布最广的有边缘拟蝇（Paraphidippus marginatus, Walk.）、狭皮拟蝇（Philodromus cespiticolis, Walk.）、拟蝇（Philodromus sp.）、重复蜘蛛（Araniella displicata, Hentz）和一种未被识别的水蛭科。与美国东北部和加拿大的报告进行了比较。在杀真菌的环境中，数量最多，这是因为那里的树叶更丰富、更茂盛。从杀虫剂环境中获得极低的计数。由于增加了苹果园里食肉蜘蛛的总数，卡帕恩被认为是非常值得推荐的。
Abstract An investigation into the abundance of spiders in a three-acre apple orchard of northeastern Wisconsin was conducted in a natural and two artificial environments (captan and DDT) from 1959 through 1961. Six families, 17 genera and 24 species were recorded, with 15 species of hunting spiders and 9 species of cobweb forms present. Most abundant were Paraphidippus marginatus (Walck.), Philodromus cespiticolis (Walk.), Philodromus sp., Araniella displicata (Hentz) and an unidentified species of Salticidae. Comparisons are made with reports from the northeastern United States and Canada. Highest numbers were in the fungicide environment which was attributed to the more abundant and lush foliage there. Extremely low counts were obtained from the insecticide environment. Captan was deemed highly recommendable for increasing the total number of predacious spiders in an apple orchard.
