1.本文描述了在云南弥渡、大理、昆明发现的新种潜蚤,订名为后潜蚤Tunga cal-lida sp.nov.并且还获有雄性标本1个。 2.本种和我国已有的盲潜蚤(T.caecigena)不同之处即在: (1)后头鬃只有3—5个,少于盲潜蚤的8—10个。 (2)下颚内叶长于下颚鬃,为其1.5倍,盲潜蚤的二者约同长。 (3)雄性柄状突为可动指长之倍。盲潜蚤的二者同长。 (4)雌性后胸后侧板鬃一般为1个,盲潜蚤者为2个。 (5)妊娠雌性外形为正圆形,背面突出较腹面为多,腹部第5节从后成钮扣状;盲潜蚤的外形为卵圆形,前端大,后端渐小,第5节以后呈长宽相等的锥形。 (6)寄生部位以宿主的身体后端为主,尤以肛门周围为最多;盲潜蚤则以耳翼边缘为主。 3.后潜蚤的主要宿主是沟鼠(Rattus norvegicus),黄胸鼠(R.flavipectus)和斯氏家鼠(R.sladeni),另外也寄生于长尾鼷鼠(Mus bactrianus),薛氏姬鼠(Apodemus agrariuschevrieri)和绒鼠(Eothenomys sp.)。 4.后潜蚤在每一宿主上可能多至45个,但以1—10个者为最常见(100例中有81例)。 5.我们采集的时间是1951年11月至1952年3月,因此可能它和盲潜蚤有相同的季节性。 6.四川五通桥市寄来潜蚤标本经鉴定为盲潜蚤,因此盲潜蚤的分布范围有进一步了解的必要。 7.1956年2—3月自贵阳的黄胸鼠和沟鼠体上获得后潜蚤,由于各仅 相似文献

鼠耳蚤是从我国首先报告的一种蚤类,由Blandford(1894)误定为Tunga pene-trans,後经Jordan和Rothschild(1921)监定系另一种蚤,命名为Tunga caecigena。 据过去记载,它的宿主有沟鼠(Rattus norvegicus)和家鼠(Rattus rattus)两种,但就 相似文献

基于12S rRNA和16S rRNA基因序列探讨中国蚤蝇科部分属间的系统发育关系 总被引:2,自引:0,他引:2
基于线粒体12S rRNA和16S rRNA基因序列联合分析,采用最大简约法、最大似然法和贝叶斯法分别构建了中国蚤蝇科14属的系统发育树.结果表明:联合分析序列总长度为819 bp,其中可变位点277个,简约信息位点200个;A+T平均含量为77.7%,具A、T偏倚性.系统发育分析显:中国蚤蝇科为单系发生,分为蚤蝇亚科和裂蚤蝇亚科两个单系群.蚤蝇亚科内脉蚤蝇属、锥蚤蝇属和刺蚤蝇属亲缘关系较近,栅蚤蝇属与栓蚤蝇属亲缘关系较近;裂蚤蝇亚科中虼蚤蝇属与裂蚤蝇属互为姐妹群,寡蚤蝇属与伐蚤蝇属互为姐妹群. 相似文献

M. E. J. Gore 《Ibis》1968,110(2):165-196
A short account of the geography of Sabah, North Borneo, is followed by a survey of the main habitats and bird communities. The greater part of the paper is devoted to a check-list of the birds of Sabah, which incorporates information collected since the standard work on Borneo by Smythies (1960). 504 species belonging to 65 families have been recorded. 相似文献

白岩脚洞石器类型的研究 总被引:4,自引:2,他引:2
本文讨论和分析了贵州普定白岩脚洞发现的砾石石器(砍砸器)和石片石器的类型。刮削器数量多,类型复杂,加工精致;尖状器数量较少,加工也不很精致;端刮器和修背石刀不太发达;雕刻器和凹缺刮器并不发达;砍砸器仍占相当比例。 相似文献

A STUDY OF THE DIFFUSIBLE FACTOR RELEASED BY THE JELLY OF THE EGG OF THE TOAD, BUFO ARENARUM 总被引:2,自引:2,他引:0
Some properties of an essential factor for fertilization released from the oocyte strings of the toad, Bufo arenarum were studied. All the experiments were carried out with a partially purified preparation of this diffusible factor, and the general procedure consisted in assaying under different conditions its capacity to recover the fertilizability of oocytes previously deprived of this active substance. Using this procedure, a test was devised for estimating the diffusible factor activity.
As regards the mechanism of action of this fertilization factor the data reported here are not consistent with the previous assumption that the factor plays its role in fertilization through a simple pH rise of the inseminating medium.
Treatment of the gametes with the diffusible factor before insemination proved to be ineffective to promote fertilization; the factor must be present at the very moment of insemination. 相似文献
