摘　　要：根据卵巢的组织学和形态特征分析,虎纹捕鸟蛛的卵巢为若干由生殖上皮向卵巢腔内突起的卵巢小体构成.在卵细胞发育过程中,一直有滋养细胞形成的托柄向其供应养分.卵巢发育可分为5个时期:形成期、生长期、成熟期、排卵期和恢复期.在生殖季节里可多次产卵,为多次产卵类型.卵巢的大小重量与蛛体重量成正相关,而成熟的蜘蛛性腺指数仅随卵细胞的发育而变化,不随蛛体大小改变.According to the histological and morphological analysis, the ovary of selenocosmia huwena is the ovarian tubule, which are sticking out from geninal epithelium into ovarian carity. Nutrition is provided composed of through the pads which are made up of the nutrient cells during oocyte developing process. There are five stages in the ovary development：formation stage, mature stage, growth stage, ovulation stage and recovery stage. The spider can lay eggs several times in the reproductive periods. So it is polyovulation type. There are positive correlation in the size and weight of the ovary with the weight of the spider＇ s body. The sexual gland exponent of the spider is changing with the oocyte developing but not with the size of the mature individuals.
