内蒙科尔沁草原淡水螺吸虫幼虫期的调查研究

本文报道在内蒙科尔沁草原检查5种淡水螺:耳萝卜螺、卵萝卜螺,豆螺、凸旋螺及半球多脉扁螺共5,616粒。从中查出至少12种吸虫幼虫期,它们是:土耳其斯坦东毕吸虫、有棘血居吸虫、马蹄吸虫、斜睾吸虫、二种背孔吸虫、棘口类吸虫、重盘吸虫、球孔吸虫、异形科吸虫、杯叶科吸虫及鹗形吸虫。其中东毕吸虫、血居吸虫及棘口吸虫的尾蚴分别进行实验动物的感染试验,获得成虫。各吸虫侵袭期幼虫季节动态亦经观察。     

青海高原牛羊双腔吸虫病病原生物学的初步调查

不文报道在青海高原对牛羊双腔吸虫病病原生物学初步调查的结果。从29个流行地区绵羊收集的标本检查结果,发现有四种双腔吸虫,它们是中华双腔吸虫(Dicrocoelium chinensis)、矛形双腔吸虫(D.lanceatum)、客双腔吸虫(D.hospes)和枝双腔吸虫(D.dendriticum)。从三个流行区检查Helicella candacharica及Cathaica przewalskii二种陆地蜗牛,查到四种双腔吸虫成熟尾蚴,它们是中华双腔吸虫、矛形双腔吸虫及二种未定名的双腔吸虫尾蚴,此二种尾蚴是何种双腔吸虫尾蚴,尚待进一步研究。检查流行区中7种蚂蚁是于9月份从乐都的Formica gagates查到双腔吸虫囊蚴,其形态与中华双腔吸虫囊蚴十分相像。     

内蒙古自治区鸟梁素海水禽寄生吸虫和线虫的初步调查

1960年5—8月期间,我组参加中国科学院动物研究所组织的内蒙古综合考察队,在乌梁素海60—70万亩水域面积上进行了水禽寄生吸虫和线虫的调查。我们解剖了30种鸟类共123只,所检获的标本经鉴定有吸虫12种,线虫15种,隶属2纲11科16属(表1,2)。其中包括两新种线虫、6种吸虫及9种线虫的国内新记录。15种鸟为6种吸虫和11种线虫的新宿主。6种鸟为6种吸虫和2种线虫在国内首次记录的宿主。     

河南省马铁菊头蝠肠道寄生吸虫

2003年8月至2006年12月对河南省7个产地35只马铁菊头蝠肠道检查, 发现吸虫5种, 隶属于3科4属.即:软体肠前腺吸虫、长形肠前腺吸虫、软体亚睾吸虫、朝鲜斜睾吸虫和中孔吸虫未定种.马铁菊头蝠是软体亚睾吸虫的新宿主.软体肠前腺吸虫、长形肠前腺吸虫、软体亚睾吸虫是河南省蝙蝠寄生虫的首次报道.     

依据ITS rDNA序列探讨我国盾腹虫属种类的系统发育关系(英文)

盾腹吸虫为寄生扁形动物中一小的类群。我国已报道7种盾腹吸虫,其中5种隶属于盾腹虫属(Aspidogastridae,Aspidogastrinae)。研究测定了在我国采集到的4种盾腹虫属吸虫的核糖体DNA转录内间隔区(ITSrDNA)序列,并分别采用邻接法和最大似然法构建分子系统发育树。结果显示,这4种盾腹吸虫的ITS-1和ITS-2序列的长度分别在728—877bp和518—645bp之间,其G+C含量分别在50.1%—52.3%和49.2%—52.2%范围内。4种盾腹吸虫的种间遗传距离在0.2%—26.9%之间,其中重庆盾腹吸虫(Aspidogaster chongqingensis)和似螺盾腹吸虫(A.limacoides)间仅为0.2%。所构建的最大似然树和邻接树具有相同的拓扑结构,均支持重庆盾腹吸虫和似螺盾腹吸虫亲缘关系最近,它们与饭岛盾腹吸虫(A.ijimai)亲缘关系较近,而与位于系统树基部的贝居盾腹吸虫(A.conchicola)关系较远。此外,对我国盾腹属种类的宿主特异性进行了讨论。     

我国乌鹳小肠的棘口科吸虫

在我国乌鹳(Ciconia nigra Linnaeus)的肠内找到三种棘口类吸虫,为乌鹳异棘口吸虫、新种(Allechinostomum nigriconiatum sp.nov.),中国肿头吸虫、新种(Chaunocephalus sinensis sp.nov.),肿头吸虫(Chaunocephalus ferox Dietz,1909)。对两个新种作了描述。 乌鹳异棘口吸虫、新种与该属的其他各种主要区别在具有卵巢后子宫环盘曲。中国肿头吸虫、新种与肿头吸虫的区别主要在卵黄腺滤泡呈横行排列,分布向后达体后部、角棘较小等特征,并与该属的其他种也作了比较。肿头吸虫属种的发现不但在我国而且在东亚均为首次。 文内对异棘口吸虫属(Allechinostomum Odhner,1910) 与肿头吸虫属(Chaunocephalus Dietz,1909)的分类位置各作了论述,并均列有种的检索表。     

黑斑蛙双睾吸虫的生活史研究

本文首次研究了黑斑蛙双睾吸虫的生活史。实验证明这种单殖吸虫的生活史具有两种不同的途径,即直接外生周期和直接内生周期。前一种发育途径为一般多盘吸虫所共有,后一种发育途径仅在少数多盘吸虫中存在。这两种发育途径的交替存在与其两栖动物宿主生态学有关,并且可能反映了这类多盘吸虫的一种种群调节机制。     

吉林省凤头麦鸡中吸虫三新种的记述

我国鸟类吸虫已有不少报道,但吉林省鸟类吸虫仅有少数几篇报告。Yamaguti等(1942)报告了吉林省吉林和长春野禽吸虫4种。浅田(1942)对东北蠕虫的总结中,仅有极少数是鸟类吸虫。吉林省农业科学院兽医研究所(1960)在长春地区鸡中发现棘口吸虫,感染率5.8％。姜泰京(1965)在延边地区家禽和野鸭中发现吸虫7种。我教研室对吉林省鸟类血吸虫进行了研究,部分虫种已作了报道(刘兆铭等,1963,1974,1976;白功懋等,1963,1978)。     

九龙江口河蚬体内寄生的3种盾盘吸虫的报道

2004年1月~2005年1月间,作者调查了闽南九龙江下游河蚬寄生的吸虫种类,在18808只河蚬中发现隶属于盾盘亚纲Subclass Aspidogastrea、腹盾科Aspidogastridae Poche,1907的3种吸虫:饭岛腹盾吸虫As-pidogaster ijimaiKawamura,1915,中华杯盾吸虫Cotylaspis sinensisFaustetTang,1936,东方簇盾吸虫Lopho-taspis orientalisFaustetTang,1936。其中饭岛腹盾吸虫和中华杯盾吸虫处于生殖器官尚未成熟的幼虫阶段。     

Six new species of the genus Dicranosepsis Duda (Diptera, Sepsidae) from Vietnam, with a revised key to the species

The flies of the genus Dicranosepsis from Vietnam were investigated and classified taxonomically. Six new species (D. longa sp. nov., D. kurahashii sp. nov., D. monoseta sp. nov., D. sinuosa sp. nov., D. barbata sp. nov., and D. vietnamensis sp. nov.) are described and illustrated. Dicranosepsis is redefined and a revised key to the species is also provided.     

Four new yeast species of the genus Sporobolomyces from plant leaves

Among the ballistoconidium-forming yeast strains isolated from various plant leaves collected in North and Northeast China, 12 strains forming orange to orange-red colored colonies were revealed to represent four novel species of the genus Sporobolomyces by conventional, chemotaxonomic and molecular phylogenetic studies, based on the 26S-rDNA D1/D2 domain and internal transcribed spacer (ITS) region sequences. Sporobolomyces beijingensis sp. nov., represented by eight strains (type strain CB 80T = AS 2.2365T = CBS 9730T), and Sporobolomyces jilinensis sp. nov., represented by two strains (type strain CB 118T = AS 2.2301T = CBS 9728T), clustered in the Johnsonii clade of the Sporidiobolus lineage. Sporobolomyces clavatus sp. nov., represented by strain CB 281T (= AS 2.2318T = CBS 9729T), belonged to the Agaricostilbum lineage and showed a close relationship to Sporobolomyces ruber and Sporobolomyces dracophylli. Sporobolomyces symmetricus sp. nov., represented by strain CB 64T(= AS 2.2299T = CBS 9727T), formed nearly symmetrical ballistoconidia and was closely related with Sporobolomyces vermiculatus and Sporobolomyces gracilis in the Gracilis clade of the Erythrobasidium lineage.     

The Larva and Pupa of Pseudoneureclipsis lusitanicus Malicky, 1980 (Trichoptera: Hydropsychoidea): Description,Ecological Data and Taxonomical Considerations

Pseudoneureclipsis lusitanicus Malicky, 1980, is reported from a large tributary of the Loire River, the first record of this genus and species from France. In Europe, this genus was previously known from Portugal. Larval and pupal characters suggest that the genus does not belong to the family Polycentropodidae, as currently classified.     

槐尺蠖和银纹夜蛾寄生微孢子虫三新种记述

中国松塔牛肝菌属新种和新记录种

本文报道松塔牛肝菌属四个新种,即:裸皱松塔牛肝菌Strobilomyces gla-bellus Ying sp.nov.,阔裂松塔牛肝菌S.latirimosus Ying sp.nov.,微茸松塔牛肝菌S.subnudus Ying sp.nov.,短绒松塔牛肝菌S.velutinus Ying sp.nov.;及四个中国新记录种,即:柔鳞松塔牛肝菌S.mollis Corner,疣鳞松塔牛肝菌S.nigricans Berk.,锥鳞松塔牛肝菌S.polypyramis Hook.,半裸松塔牛肝菌S.semi-nudus Hongo.松塔牛肝菌属Strobilomyces以其具有变黑的担子果与菌幕、不粘的菌盖上有疣状、绵绒状或刺状鳞片以及黑褐色带明显纹饰的孢子而易于识别。Singer(1945)按孢子纹饰的不同将松塔牛肝菌属分为两个组,其一为具疣、刺和网纹的种类;另一为具纵贯孢子两端的翼状棱纹的种类。对于后者的归属问题,Pegler & Young持不同见解,并于1981建立了非洲牛肝菌属AfroboletusPegler & Young以纳孢子具翼状纵棱和孢缘边(rim)的种类;含2—4种,分布在非洲近赤道的地区。在中国,松塔牛肝菌属已报道过三个种,即:松塔牛肝菌Strobilomyces,floc-copus(Vahl.ex Fr.)Karst.光头松塔牛肝菌S.glabriceps Chiu和混淆松塔牛肝菌S.confusus Sing.。裘维蕃(1948,1957)曾描述过网孢松塔牛肝菌Strobi-lomyces retisporus(Pat.et Bak.)Gilb.但因其子实体色鲜红至褐红而不变黑色、子层体淡暗黄色且菌肉不变红-黑色、孢子具网纹而宜转隶于Heimiellia Boedijn(1951)。文中有新分类单位和国内已知种的分种检索表、新种的拉丁文和英文描述并有绘图和扫描电镜照片示明孢子纹饰。     

子囊菌二新种

本文报道在我国东北地区发现寄生在落叶松(Larix Mill.)上的二个子囊菌新种——多孢小黑腐皮壳(Valsella multispora sp.nov.)及落叶松隐腐皮壳(Cryptovalsa laricina sp.nov.)。其形态特征有汉文和拉丁文描述以及显微照像图版。
