Journal of Morphology, 2013 Many gamasid mites, mainly of the taxon Dermanyssina, possess a secondarily evolved insemination system that is generally described as occurring in two types, the laelapid and the phytoseiid-type, which are structurally considerably different ...

Communities of gamasid mites on Eothenomys miletus in southwest China
Biologia, 2015The Yunnan red-backed vole (Eothenomys miletus) is an endemic and specific wild rodent species in China. From 39 sites across southwest China, a total of 12,536 individuals of gamasid mites were collected from 2,463 voles between 2001 and 2013. The 12,536 mites were identified as comprising 106 species, 26 genera and 9 families.

Inferring associations among parasitic gamasid mites from census data
Oecologia, 2009Within a community, the abundance of any given species depends in large part on a network of direct and indirect, positive and negative interactions with other species, including shared enemies. In communities where experimental manipulations are often impossible (e.g., parasite communities), census data can be used to evaluate the strength or ...

Ultrastructural Study of Spermatogenesis in Gamasid Mites (Acari, Gamasida)
Acta Zoologica, 1991AbstractStructural alterations accompanying the development of germ cells in representatives of two families of gamasid mites: Pergamasidae (Pergumasus barbarus. P. truatellus) and Parasitidae (Porrhostaspis lunulata) were examined by scanning electron microscopy. Spermatogenesis occurs in cysts containing two (P.

Embryonic development of gamasid mites (Parasitiformes: Gamasida)
International Journal of Acarology, 1992ABSTRACT An account is given of embryonic development in the Gamasida including details of cleavage and gastrulation, and early, prelarval and larval morphogenesis. The specialized development of the Spinturnicidae is compared with that of other gamasids.

[The effects of six kinds of insecticides on gamasid mites].
Zhonghua yu fang yi xue za zhi [Chinese journal of preventive medicine], 1990The 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 ...

Gamasid Mites (Gamasoidea, Parasitiformes) of the Caucasus
1973The 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.

Infestation with Gamasid Mites
1984Attacks 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

Some Considerations on the System and Phylogeny of Gamasid Mites
1973Reuter (1909) was the first acarologist who regarded the Gamasid mites as a superfamily Gamasoidea or Parasitoidea. In my former papers I used this rank for Gamasid mites. But later it became evident that some of the families belonging to this complex may be united into several natural groups of a higher rank, namely superfamilies (Evans, 1955; Lange ...
