中国人. 应用常规内部解剖方法,对小黑瓢虫[Delphastus catalinae（Horn）]生殖系统的结构和卵巢发育情况进行了研究.结果表明：雌性生殖系统主要包括1对卵巢、1对侧输卵管、1条中输卵管、1个受精囊、交配囊、附腺、黏腺、外生殖片等;雄性生殖系统主要包括睾丸、1对储精管、1对输精管、射精管及1对附腺、弯管和阳基等;不同发育时期小黑瓢虫卵巢管数量均为8根;根据外部形态特点以及卵黄沉积的情况,将小黑瓢虫的卵巢发育分为未分化期、生长发育初期、生长发育中期、生长发育后期、成熟产卵前期、成熟产卵期等6个阶段.[著者文摘]

The reproductive system and ovarian development of Delphastus catalinae（Horn） were investigated by anatomical method.The results showed that the reproductive system of female adult was constituted by a pair of ovaries,a pair of oviducts,median oviduct,spermatheca,bursa copulatrix,accessory glands,sticky glands and genital plate.The reproductive system of male adult was constituted by a pair of testes,a pair of seminal vesicles,a pair of seminal ducts,ejaculatory duct,a pair of male accessory glands,shipo and penis.Ovarioles of D.catalinae were constantly 8 in different developmental stages.Based on external morphology characteristics and the vitellines deposition conditions,the ovarian development in the adult stage of D.catalinae could be divided into 6 stages.[著者文摘]
