广西玉米蜘蛛有19科81种。南宁市平原区玉米蜘蛛群落结构,早玉米以食虫沟瘤蛛(Ummeliatainsecticeps),晚玉米以锥腹肖蛸(Tetragnathamaxilosa)和草间小黑蛛(Erigonidiumgraminicolum占数量优势。群落成员的个体数量高峰,早、晚造玉米均出现在生长中期。群落多样性早造由低到高,晚造由高到低。时间生态位测定表明,食虫沟瘤蛛与幼豹蛛(Pardosapusiola),草间小黑蛛与类奇异獾蛛(Trochosaruricoledes)分别是早造和晚造玉米蜘蛛群落中利用资源最广的种群。文中分析了玉米蜘蛛群落结构的季节变动,与邻近稻田蜘蛛群落结构的相互关系。
There are 19 families and 81 species of Guangxi corn spiders. The structure of maize spider community in the plain of Nanning City was early maize with Ummeliatainsecticeps and late maize with Tetragnathamaxilosa and Erigonidium graminicolum as the number of individuals, Early and late maize all appeared in the mid-growth stage.The community diversity was changed from low to high in early and late to high in late.Estimation of niche showed that there was no significant difference between the two groups in Pardosapusiola, Tarantulas and Trochosaruricoledes were the most widely used populations of early and late maize spiders respectively.The seasonal variation of the structure of the maize spider community and its relationship with the spider community structure of the neighboring rice fields were analyzed.
