Penthaleus Major
''Penthaleus major'', known generally as the winter grain mite or blue oat mite, is a species of earth mite in the family Penthaleidae. They are black or dark blue in color and are widespread across the world. They are commonly found on oats and in pastures and spend most of their time on the surface of soil, and are occasionally found on wheat, barley, peas, lentil and lucerne, and seldom on canola. Description The blue oat mite measures anywhere from 1/32 to 1/16 inch, and has orange-red legs and a dark blue to black body with a red or orange spot on its upper abdomen. Their front legs are barely the longest. Blue oat mite anuses are dorsal. Right after they hatch from their eggs, these mites are pink-orange colored, then brownish in a short time, before turning green and eventually becoming adults. Blue oat mite larvae are about 0.3 millimeters in length, 6-legged, and oval. Distribution and habitat The blue oat mite has been reported across the world, in New Zealand, Austra ...

Anthonie Cornelis Oudemans
Anthonie (Antoon) Cornelis Oudemans Jzn (November 12, 1858 – January 14, 1943) was a Dutch zoologist. Although he was a specialist in acarology, the study of the ticks and mites, he was often best known for his books on sea monsters and the dodo. Born in Batavia, Dutch East Indies, he was the son of the noted Dutch astronomer Jean Abraham Chrétien Oudemans and the grandson of the Dutch educator, poet and philologist Anthonie Cornelis Oudemans Sr., after whom he was named. He often used the patronymic "Jzn" (for ''Jeanzoon'') in his publications. A cousin was the entomologist J.T. Oudemans. He was educated at Arnhem and went to the University of Utrecht. He wrote his dissertation on ribbon worms, and in 1885 was appointed director of the Royal Zoological Gardens at The Hague. Oudemans worked on the acari and comprehensively reviewed all literature until 1850 in a series of articles titled ''Kritisch historisch Overzicht der Acarologie''. He described numerous species not on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 predators or 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 distinct groups of arachnids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australia
Australia, officially the Commonwealth of Australia, is a sovereign ''Sovereign'' is a title which can be applied to the highest leader in various categories. The word is borrowed from Old French , which is ultimately derived from the Latin , meaning 'above'. The roles of a sovereign vary from monarch, ruler or ... country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of , Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical Forests of Australia, rainforests in the north-east, and List of mountains in Australia, mountain ranges in the south-east.

Transactions Of The Royal Society Of South Australia
The Royal Society of South Australia (RSSA) is a learned society whose interest is in science, particularly, but not only, of South Australia. The major aim of the society is the promotion and diffusion of scientific knowledge, particularly in relation to natural sciences. The society was originally the Adelaide Philosophical Society, founded on 10 January 1853. The title "Royal" was granted by Queen Victoria in October 1880 and the society changed its name to its present name at this time. It was incorporated in 1883. It also operates under the banner Science South Australia. History The origins of the Royal Society are related to the South Australian Literary and Scientific Association, founded in August 1834, before the colonisation of South Australia, and whose book collection eventually formed the kernel of the State Library of South Australia. The Society had its origins in a meeting at the Stephens Place home of J. L. Young (founder of the Adelaide Educational Instituti ...

Trombidiformes
The Trombidiformes are a large, diverse order of mites. Taxonomy In 1998, Trombidiformes was divided into the Sphaerolichida and the Prostigmata. The group has few synapomorphies by which it can be defined, unlike the other major group of acariform mites, Sarcoptiformes. Its members include medically important mites (such as '' Demodex'', the chiggers, and scrub-itch mites) and many agriculturally important species, including the spider mites (Tetranychidae). The superfamily Eriophyoidea, traditionally considered members of the Trombidiformes, have been found to be basal mites in genomic analyses, sister to the clade containing Sarcoptiformes and Trombidiformes. The 2004 classification retained the two suborders, comprising around 125 families and more than 22,000 described species. In the 2011 revised classification, the order now contains 151 families, 2235 genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fo ...

Taxa Named By Anthonie Cornelis Oudemans
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
