摘　　要：采用吸虫器法对辽宁开原稻区蜘蛛种类及其在田间发生动态进行调查,结果表明,主要蜘蛛种类有7科共14种,其中,优势种蜘蛛为拟水狼蛛和草间钻头蛛,优势度指数分别为13.6和11.23,其余有8种丰富种和4种常见种,种类较丰富。对两种优势蜘蛛的田间消长动态进行调查,可知8月是两种蜘蛛个体数量最多的时期,至10月水稻收割时仍维持一定的种群数量。The species and variation of spiders in Kaiyuan rice area of Liaoning Province were investigated.The results showed that there were 14 species in 7 families.Among them,the dominant species were Pirata subpiraticus and Erigonidium graminicolum,with dominance index of 13.6 and 11.23,respectively.The rest have 8 rich species and 4 common species,the species is relatively rich.The variation of the two dominant spiders in the field were investigated.It was found that the individual number of the two spiders reached the maximum in August,and it still maintained a certain population number when the rice was harvested in October.
