Host-specificity and host-selection of gamasid mites (Acari: Gamasina)

Systematic and Applied Acarology, 1998
Abstract Using methods to evaluate ecological niche breadth and overlap, I studied the host-specificity and the host-selection of 11 species of gamasid mites collected from 25 species of small mammals in western Yunnan, China, Levins' niche breadth was used for host-specificity, while Colwell-Futuyma's niche overlap and a fuzzy clustering analysis were

F‐Actin and Tubulin During Spermatogenesis in Gamasid Mites (Acari: Parasitina)

Acta Zoologica, 1993
Abstract F‐actin and tubulin behaviour was investigated using fluorescence probes and electron microscopy in the course of spermatogenesis in two gamasid mites, Porrhostaspis lunulata Müller (Parasitidae) and Pergamasus truatellus Athias‐Henriot (Pergamasidae).

Infestation with Gamasid Mites

1984
Attacks on man by members of the family Gamasidae (suborder Mesostigmata) have been recorded on a worldwide basis. They not only cause irritating skin eruptions but are also known or suspected vectors of several rickettsial and viral diseases (Table 17.1). Hirst (1922) enumerated five species which attacked humans. The nomenclature of this group in the

Gamasid Mites (Gamasoidea, Parasitiformes) of the Caucasus

1973
The natural conditions of the Caucasus, where large areas of semi-deserts and mountain steppes alternate with sub-alpine and alpine meadows and snow-capped peaks, are extremely varied. Nearly all climatic and vegetation zones are represented here and due to this fact the fauna of gamasid mites of all the Caucasus includes 200 species.

Distribution of gamasid mites on small mammals in Yunnan Province, China

Insect Science, 2007
AbstractAn investigation of gamasid mites on the body surface of small mammals was carried out in Yunnan Province of China from 1990 to 2004. The small mammal hosts were captured from 25 counties which represent five geographical subregions, namely Middle Subregion of Hengduan Mountains, Southern Subregion of Hengduan Mountains, Eastern Plateau ...

[Proliferation and location of Hantaan virus in gamasid mites and chigger mites, a molecular biological study].

Zhonghua yi xue za zhi, 2003
To study the proliferation and location of Hantaan virus (HV) in gamasid mites and chigger mites and the significance of gamasid mites and chigger mites as vectors of transmission of hemorrhagic fever with renal syndrome (HFRS).Gamasid mites collected from the nests of wild rodents and chigger mites collected from the bodies of wild rodents and thick ...

[The effects of six kinds of insecticides on gamasid mites].

Zhonghua yu fang yi xue za zhi [Chinese journal of preventive medicine], 1990
The present paper reports on the results of six kinds including 14 chemical or biological insecticides on the gamasid mites. (1) Using organophosphorus compounds such as quinothion, supracide, bromochlophus, sumithion at a dose of 0.2g per m2, at a dose of 1 g per m2 abate, and malathion at a dose of 49 per m2, they were all sufficient to produce 100 ...

Host selection of ectoparasitic gamasid mites on Tylonycteris pachypus and T. robustula

Zoological Research, 2013
Correlations of two species of gamasid mites (Macronyssus pararadovskyi and M. radovskyi) and their bat hosts (Tylonycteris pachypus and T. robustula) were studied by field surveys and indoor behavioral experiments. The wild data indicated that mite load was positively correlated with body condition index of female T.

Reproductive systems of gamasid mites (Acari, Anactinotrichida) reconsidered

2002
Gamasida (=Mesostigmata) are by far the most species rich and ecologically diverse anactinotrichids. Phylogenetic relationships between gamasid taxa are not solved and even highly controversial. In parallel with this discussion, which mainly refers to characters from external morphology, arguments from anatomy, fine structure, and behaviour in ...
