摘要(Abstract):

<正> 研究蚤的内部结构及其在变态发育中生殖腺的发育和成熟,对蚤分类学,变态生理以及生态和防制的进一步研究都是重要的。缓慢菌蚤Leptopsylla segnis(Schonherr,1181)、不等单蚤Monopsyllus anisus(Rothschild,1907)和猫栉首蚤(Ctenocephalides felis(Bouche,1835)分别属于蚤目的细蚤科、角叶蚤科和蚤科。这三个科包括蚤目近一半的属,具有一定的代表性。这三种蚤都是世界广布种繁殖力强,适应于多种宿主的寄生;对人畜的危害,除吸血骚扰外,还能传播多种疾病,是公认的鼠疫传播媒介,缓慢细蚤和不等单蚤还可传播猪丹毒病、蜱源性脑炎、鼠源性斑
A study on the histological features durng the devlopment and maturation of the gonads from the third larval instar up to mature adult of Leptopsylla segnis (Schonherr, 1811), Monopsyllus anisus (Rothschild, 1907) and Ctenocephalides felis felis (Bouche, 1835) is reported in this paper. All the specimens were collected from Guiyang and reared in our laboratory. The serial sections of every developmental stage from third larval instar through pupa to mature adult were made between certain intervals by a modified Rothschild's (1975) technique. A total of 717, 209 and 158 slides were made in these three species of fleas respectively. They were stained with modified Mallory's triple stain, HE stain and treated with PAS reaction. Results of these studies are summarized as following: (1) The delveopment of the gonads of these fleas is essentially the same. However, there were differences in the number of the sperm cysts, the sperm bundles or spermatodesms and the ovarioles. The time required for the development and the degree in the formation of the spermatids, sperm bundles and tesitcular plug were different between them. (2) According to the development of the rudiments of the testes, formation and change of the spermatids and spermatodesms etc., the development and maturation process of the male gonads from the third instar up to mature adult could be divided into 5 phases with 10 stages. (3) According to the development of the ovarial rudiments, the degree of development of the egg-cells and the follicular epithelium, the quantity of accumulated yolk and the appearnce of the chorion etc., the development and maturation process of the female gonads from the third instar up to mature adult could be divided into 4 phases with 10 staegs. Comments were made on the following: (1) the structure of testes; (2) the sperm cysts in relation with the number of the sperm bundles; (3) the degree of the development of the testicular plug in relation with the maturation of the male; (4) the earlier emergence of the females from the pupae than that of the male; (5) the "open spaces" appeared between follicular cells, when vitellogenesis began at the 8th stage during the development of the ' female gonads.
