The oribatid mite, Phthiracarus sp., feeds by tearing-out material from the spongy mesophyll of decaying spruce needles with a pair of retractile chelicerae. A pair of dentate rutella localize this tearing activity and limit particles to a manageable size. Mastication is achieved by movements of the chelicerae against each other and the rutella, th...
Article
Phthiracams sp. has one pair of coxal glands. Each gland comprises a thin-walled sacculus which is specialized for the ultrafiltration of the haemolymph and a tubular labyrinth the ultrastructure of which indicates a specialization for the active resorption of material from the lumen. In addition to its digestive function, the alimentary canal of t...

... Oricultural farming practice: a novel approach to agricultural productivity efficient and successful group of soil arthropods in temperate forest ecosystem (Johnston 1982;Norton, 1994), tropical ecosystem (Lasebikan 1977(Lasebikan , 1981Haq 1996Haq , 2007aRamani and Haq 2001) and Palaeozoic coal swamp forests (Labandeira et al. 1997). These mites are excellent triggers of bioprocessing of plant materials and release nutrients into the soil ecosystem (Hayes 1963;Berthet 1964;Dinsdale 1974;Luxton 1979;Behan and Hill 1983;Haq 1984Haq , 1994Haq , 1996Clement and Haq 1984;Wicking and Grandy 2011). Species involved in bioprocessing need to have diverse food habits (Luxton 1979;Alphonsa and Haq 2006), masticatory, microbial (Haq 1987;Haq and Konikkara 1988) and enzymatic (Dinsdale 1974;Haq 2007a) activities, to be tolerant to extremes of physical, chemical and biological factors around, and to have high consumption rate, and absorption and assimilation efficiency. ...
... Oribatids have been poorly studied (Tarras-Wahlberg 1960;Woodring and Cook 1962;Hoebel-Mävers 1967;Tarman 1968;Bernini 1971;Haarløv and Bresciani 1972;Woodring 1973;Dinsdale 1974Dinsdale , 1975Smrž 1989;Šustr and Hubert 1999;Bücking 2002;Alberti et al. 2003). Given their predominance in soils and plethora of species feeding on different material, much more work is needed on cryptostigmatid physiology. ...
