Orthohalarachne
''Orthohalarachne attenuata'' (family: Halarachnidae) is a species of mite normally found in the nasal passages of fur seals, sea lions, and walruses. In seals, the mites can be both prevalent (almost every single seal has them) and abundant (more than 1000 mites per seal). Although clinical observations and gross examination indicate that O. attenuata parasitization alone is not serious, some erosion and inflammation of the nasal turbinates and nasopharynx in seals has been observed in histological sections. If concomitant parasitization with ''O. attenuata'' and ''O. diminuta'' occurs, alveolar emphysema and more serious ailments can threaten the life of the mammal. Morphology Mature mites are shown to be elongated in the posterior part of body to form a club-shape with the rounded posterior extremity. Ten to twelve transverse rows of 8 to 12 sharp denticules and a few rows of minute spines are present on the ventral surface of the capitulum and the posterior surface of coxa II ...

Mesostigmata
Mesostigmata is an order of mites belonging to the Parasitiformes. They are by far the largest group of Parasitiformes, with over 8,000 species in 130 families. Mesostigmata includes parasitic as well as free-living and predatory forms. They can be recognized by the single pair of spiracles positioned laterally on the body. The family with the most described species is Phytoseiidae. Other families of note are Diplogyniidae, Macrochelidae, Pachylaelapidae, Uropodidae and Veigaiidae. Amongst the best known species are ''Varroa destructor'', an economically important parasite of honey bees, as well as the red mite (''Dermanyssus gallinae'') a parasite of poultry, most commonly chickens. Description Mesostigmata are mites ranging from 0.12-4 mm long (0.2-4 mm according to another source). They have a pair of stigmatal openings above legs III-IV usually associated with a peritrematal groove. The gnathosoma has a sclerotised ring around the bases of the chelicerae (basis capitul ...

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
