摘　　要：用陷阱法和目测法对丘陵区各个栖境的星豹蛛Pardosa astrigera C．L．Koch(Ly- cosidae：Pardosa C．L．Koch)做了初步调查研究,结果表明,星豹蛛5月下旬前主要在边界、沟渠、碎石路和斜坡处活动,而苹果园中相对较少。当边界、沟渠和碎石路植被长高后,星豹蛛迁移至周围的苹果园中。6月下旬7月下旬苹果园中星豹蛛受高温影响数量下降明显；8月下9月其数量又有较大回升。研究还发现,10月中下旬星豹蛛在背阴地带出现的频率明显少于光照较好的地带；同期星豹蛛可能还有趋向干枯杂草的习性。Spiders were investigated initially in every habitat Using pitfall and eye survey in the hilly land, and the result showed, Pardosa astr/gera C. L. Koch （Lycosidae ： Pardosa） mainly acted at filed margin, irrigation canals, macadam road and slope before the end of the May and its numbers was more than that in the orchard at the time. With the plant growing at the filed margin, irrigation canals, and macadam road, P. astrigera emigrated to the lateral apple orchard. Its numbers decreased obviously for high temperature at the end of June to the end of July in the apple orchard. The studies indicate that P. astrigera, emergence rate in the shady spot was less than the illumination spot obviously and it may have the habit of inclining to dried - up grass in middle and last ten days of October.
