应用对流免疫电泳测定革螨的食性

本文首次报道用对流免疫电泳法测定革螨的食性,试验结果表明:本法比较敏感,能测出单个血食革螨,特异性高,一般无假阳性,并能确定血源,故亦适于小型节肢动物嗜血习性的测定。讨论了影响结果的有关因素。对格氏血厉螨进行了吸血能力的实验观察,镜检刺吸率为58.5%,用对流免疫电泳法刺吸率为74.2%,提高了阳性检出率。采自黑线姬鼠窝中的格氏血厉螨、厩真厉螨,用兔抗黑线姬鼠血清作对流免疫电泳测定为阳性。

新疆维吾尔自治区流行病学研究所从1957—1980年间在自然疫源性疾病的调查中采到一些革螨标本,经初步整理部分标本,已定种的有20种,分隶于5科10属,其中包括赫刺螨属一新种,订名为新疆赫刺螨(Hirstionyssus xinjiangensis sp.nov.)。现报导如下: 一、血革螨科Haemogamasidae Oudemans,1926 (一)真厉螨属Eulaelaps Berlese,1903 1.厩真厉螨E.stabularis(Koch,1836) 宿主:褐家鼠(Rattus norvegicus)、子午沙鼠(Meriones meridianus)、五趾跳鼠(Allactaga sibirica)、灰仓鼠(Cricetulus migralorius)。 采集地点、时间:吐鲁番、和田、奇台北塔山、乌鲁木齐。5—8月。 2.仓鼠真厉螨E.cricetuli Vitzthum,1930 宿主:小毛足鼠(Phodopus roborowskii)三趾跳鼠(Dipus sagitta)。 采集地点、时间:和田。7月     

青海省寄生螨类的区系分布

根据建国以来的大量研究调查资料,对青海地区已记载的寄生螨类（主要包括革螨、恙螨）计10科33属100余种进行了初步的区系分布、数量与宿主关系的探讨。（1）河湟谷地小区[1]：计有45种,主要有：赛氏血革螨、秉氏血革螨、旱獭青厉螨、毒厉螨、鼠兔赫刺螨、褪色巨螯螨、似田鼠新恙螨、旱獭新恙螨等;（2）柴达木盆地小区：计有15种,具代表性种类为乌兰纤恙螨;（3）祁连青南小区：计有85种,具代表性种类为久治真棒恙螨、玉树羽叶恙螨和朱雀禽棒恙螨;（4）羌塘高原小区：计有3种,皆为血厉螨属种类。     

云南医学革螨数值分类研究

以云南省57种医学革螨作为分类单元,以形态特征为主列出60项分类性状特征来探讨云南省医学革螨不同属和种的亲缘关系。运用SPSS 11.5 统计软件中的系统聚类分析和主成分分析,对57种医学革螨进行了数值分类分析。结果显示：57种医学革螨划分为厉螨科（La elapidae）、寄螨科（Parasitidae）、皮刺螨科（Dermanyssidae）、赫刺螨科（Hirstionyssidae）和裂胸螨科（Aceosejidae）5个类群。赫刺螨属和棘刺螨属从厉螨科中分离出来另立为赫刺螨科,柏氏禽刺螨归入了皮刺螨科而不是巨刺螨科。分类结果与传统形态分类结果基本一致,因而认为数值分类能比较客观地反映医学革螨各分类阶元的分类地位与亲缘关系。

辽宁省蜱类的生态地理分布

辽宁省已知的蜱类共13种, 分属于2科6属.本文依据不同地理景观区内蜱的种类与数量, 并结合其不同生境类型, 对蜱类的生态地理分布问题作了讨论.四个地理景观区内蜱种类与数量情况如下:(1)黄土丘陵台地干草原与西辽河风沙草原区:黄土丘陵台地干草原区蜱种类少, 但数量多.草原血蜱为优势种, 草原硬蜱数量较少.西辽河沙地草原区有草原血蜱、草原革蜱、草原硬蜱, 前两种均为优势种.(2)辽西山地疏林灌从区:本区有森林革蜱、长角血蜱、全沟硬蜱及日本锐缘蜱, 前两种为优势种.(3)辽东山地森林及林缘草地区:本区蜱种较多, 林区以日本血蜱、嗜群血蜱、全沟硬蜱为多见;林缘草地以长角血蜱、森林革蜱为优势种, 另外还有钝跗硬蜱、血红扇头蜱.(4)平原丘陵农区:木区蜱种虽然不少, 但分布局限, 数量小.有长角血蜱、草原血蜱、森林革蜱、微小牛蜱, 波斯锐缘蜱.     

川西南地区小型兽类型体外寄生革螨群落研究

1987年7月－1988年11月在川西南地区共采集到小型兽类体外革螨32种,178只,高山姬鼠,大耳姬鼠和社鼠体外寄生革螨群落结构复杂,生物多样性指数较高,在这些革螨群落中,如厩真厉螨为高山姬鼠和大耳姬鼠的优势种,福建厉螨为社鼠的优势种,毒厉螨为褐家和阳金小鼠的优势种,松鼠真厉螨为橙腹松鼠的优势种,金氏厉螨为黑腹绒鼠的优势种,臊鼠赫刺螨为灰麝鼯的优势种,而其余12种小型兽类革螨群落的优势种不明显。     

中国云南西部小哺乳动物革螨的性比及年龄结构(英文)

1990～ 1 996年对中国云南西部 1 3个县进行了调查 ,从所捕获的 38种、30 2 3只小哺乳动物体表采集到革螨 70种、7485只。绝大多数革螨的雌性个体比例 ( 80 %～ 1 0 0 % )高于其雄性个体比例 (P <0 .0 1 ) ,唯贡山血革螨Haemogamasusgongshanensis和格氏血厉螨Haemolaelapsglasgowi例外。贡山血革螨的雄性个体比例高于其雌性个体比例 (P <0 .0 1 ) ,格氏血厉螨的雌雄比例接近 (P >0 .0 5)。在现场采集中 ,绝大多数革螨种类未见幼虫阶段。除柏氏禽刺螨Ornithonyssusbacoti及格氏血厉螨Haemolaelapsglasgowi的若虫比例 (分别为 62 .84%和 49.48% )较高外 ,绝大多数革螨的未成熟期 (主要是前若虫和后若虫 )比例( 0～ 1 2 .84% )明显低于成虫期比例 (P <0 .0 1 )。采自小哺乳动物体表革螨雌雄性比的不同可能与雌雄螨的吸血习性及孤雌生殖有关。绝大多数革螨在其宿主体表缺乏幼虫阶段以及若虫比例很低提示 :这些革螨的幼虫或若虫阶段可能不取食或不吸血 ,主要生活在宿主的窝巢内。另一种可能原因是某些革螨的雌螨可能直接产前若虫或后若虫 ,因此难以从宿主体表发现幼虫。     

小鼯鼠体上的两种革螨包括血厉螨属一新种

Role of gamasids in the epizootiology of tularemia]

10 strains of Francisella tularensis were isolated from 4 species of gamasid mites, Laelaps muris, L. multispinosus, Hyperlaelaps amphibius and Haemolaelaps glasgowi, in natural nidi of tularemia in the Tumen district. Under experimental conditions L. muris is often infected with tularemia agent on sick animals but preserves it at an indoor temperature not more than a week and does not transmit it transovarially. Haemogamasus ambulans preserve the agent within the same period. L. muris and Hirstionyssus isabellinus do not transmit the tularemia agent to healthy animals through a bite.     

Characteristics of zonal distribution of the gamasid mites connected with small mammals and their nests in Western Siberia

Analysis of long-term data on the fauna, landscape distribution, and structure of communities of the gamasid mites (Acari:Parasitiformes:Mesostigmata) connected with small mammals and their nests in the plain part of Western Siberia is carried out. By now, presence of 249 gamasid mite species is established in the territory under study, including 193 free-living and 56 parasitic species. Gamasid mites are represented by the maximal number of species on small mammals and in thers nests in northern forest-steppe (102 and 105 species respectively). Nine parasitic species from two ecological groups (epizoic and nidicolous) were found in all landscape zones of the West Siberian Plain, namely: 1) epizoic species Laelaps clethrionomydis Lange, 1955, Laelaps hilaris C. L. Koch, 1836, and Hyperlaelaps arvalis Zachvatkin, 1948 (obligatory non-exclusive hematophagous); 2) nidicolous species Androlaelaps casalis Berlese, 1887 (obligatory non-exclusive hematophagous), Eulaelaps stabularis C. L. Koch, 1836, Haemogamasus nidiformnes Bregetova, 1955 (facultative hematophagous), Haemnogamnasus ambulans Thorell, 1872 (obligatory non-exclusive hematophagous), Hirstionyssus isabellinus Oudemans, 1913, and Hirstionyssus eusoricis Bregetova, 1956 (obligatory exclusive hematophagous). Last three species demonstrate the mixed type of parasitism. The population of gamasid mites on small mammals is most specific in tundra, southern forest-steppe and steppe; the fauna of gamasid mites in nests is most specific in southern forest-steppe and steppe.

Gamasid mites of small mammals in the semi-desert territories of Saratov Trans-Volga region

New data on the species composition and comparative analysis of gamasid mites occurring on small mammals in the semi-desert territories of Saratov Trans-Volga region are reported. In all, 18 species of gamasid mites (9 genera, 5 families) were found, including 9 species which had not been previously recorded in the region: Hypoaspis (Stratiolaelaps) miles Berlese, 1882, H. (Geolaelaps) heselhausi Oudemans, 1912, H. (G.) lubrica Oudemans et Voigts, 1904, Laelaps multispinosus Banks, 1909, L. jettmari Vitzthum, 1930, Cyrtolaelaps mucronatus G. et. R. Canestrini, 1881, Haemogamasus citelli Bregetova et Nelzina, 1952, Hirstionyssus eusoricis Bregetova, 1956, and Hi. ellobii Bregetova, 1956; 5 of these species are new to Saratov Province.     

The relationship of the population dynamics of gamasid mites with the population dynamics of their murine rodent hosts in the Sikhote-Alin]

22,500 mites were collected from 4515 rodents over a period of 5 years in the Sikhote-Alin reserve. The abundance dynamics of 4, out of 5, most numerous species of mites (Laelaps pavlovskyi, L. clethrionomydis, Eulaelaps stabularis, Haemogamasus serdjukovae) depends on the cyclic fluctuations in the number of rodents. A direct connection between the annual and, to some extent, seasonal dynamics of the abundance of parasites and that of their hosts is most distinct in L. pavlovskyi, an epizoon parasite of the large Japanese field mouse. At the same time the abundance of Hg. ambulans, a multihost parasite of small mammals, does not depend on the number of animals. Certain regularities in the abundance dynamics of gamasid mites in connection with that of their hosts, rodents, is discussed on the basis of obtained material and literary data.     

First report of mites (Gamasida: Laelapidae) parasitic on wild rodents in Uruguay, with new host records

Information is presented for the first time on laelapid mites associated with wild rodents in Uruguay. Specimens of the following species were identified: Laelapinae: Androlaelaps fahrenholzi (Berlese), Androlaelaps rotundus (Fonseca), Gigantolaelaps wolffsohni (Oudemans), Laelaps paulistanensis (Fonseca), Laelaps manguinhosi (Fonseca) and Mysolaelaps microspinosus Fonseca; Haemogamasinae: Eulaelaps stabularis (Koch). Most of the ectoparasite-host associations are reported for the first time. New host and locality records presented in this study are in accordance with previous findings on the same and/or related host species in nearby South American localities.
