picture info	Copra Copra (from ) is the dried, white flesh of the coconut from which coconut oil is extracted. Traditionally, the coconuts are sun-dried, especially for export, before the oil, also known as copra oil, is pressed out. The oil extracted from copra is rich in lauric acid, making it an important commodity in the preparation of lauryl alcohol, soaps, fatty acids, cosmetics, etc. and thus a lucrative product for many coconut-producing countries. The palatable oil cake, known as copra cake, obtained as a residue in the production of copra oil is used in animal feeds. The ground cake is known as coconut or copra meal. Production Copra has traditionally been grated and ground, then boiled in water to extract coconut oil. It was used by Pacific island cultures and became a valuable commercial product for merchants in the Polynesia, South Seas and South Asia in the 1860s. Nowadays, coconut oil (70%) is extracted by crushing copra; the by-product is known as copra cake or copra meal (30%) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Tyrophagus Longior ''Tyrophagus longior'' is a mite in the family Acaridae. Description ''Tyrophagus longior'' is oval in shape and whitish to semitransparent in colour. It is covered dorsally in barbed setae. There are eight legs (six in larvae) that are light brown in colour. Adult females of ''T. longior'' can be distinguished from others of the genus by the following: prodorsal shield without pigmented eyespots; hysterosomal setae ''d1'' about 1.3–1.8× as long as ''c1'' and ''d2'', and the alveoli (bases) of ''d1'' situated approximately midway between those of ''c1'' and ''e1;'' and tarsi I and II with solenidia that are long and slender (not expanded at the tips). Adult males similarly lack pigmented eyespots and have long, slender solenidia. Males also have a large and slender aedeagus (male reproductive organ). Life cycle Like other species of ''Tyrophagus'', ''T. longior'' has a life cycle consisting of egg, larva, protonymph, tritonymph, and adult. Habitat These mites have be ...

picture info	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]
	Coolie Itch Coolie itch is a cutaneous condition caused by '' Rhizoglyphus parasiticus'', characterized by an intense pruritus. It is found in India on tea plantations and causes sore feet.

	Skin Lesion A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. Conditions of the human integumentary system constitute a broad spectrum of diseases, also known as dermatoses, as well as many nonpathologic states (like, in certain circumstances, melanonychia and racquet nails). While only a small number of skin diseases account for most visits to the physician, thousands of skin conditions have been described. Classification of these conditions often presents many nosological challenges, since underlying causes and pathogenetics are often not known. Therefore, most current textbooks present a classification based on location (for example, conditions of the mucous membrane), morphology ( chronic blistering conditions), cause (skin conditions resul ...
