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] |
Eriophyes
''Eriophyes'' is a genus of acari that forms galls, specially on trees of the family Rosaceae. Some are called blister mites. The blue butterfly '' Celastrina serotina'' has been reported to feed on these galls and also on the mites, making it one of the uncommon carnivorous Lepidoptera. Species Species include: * '' Eriophyes alniincanae'' Nalepa, 1919 * '' Eriophyes amelancheus'' Nalepa, 1926 * ''Eriophyes arianus'' (Canestrini 1890) * '' Eriophyes betulae'' * '' Eriophyes betulinus'' * '' Eriophyes bucidae'' * '' Eriophyes buxi'' * ''Eriophyes calcercis'' , purple erineum maple mite * '' Eriophyes calophylli'' * '' Eriophyes calycophthirus'' * ''Eriophyes canestrini'' * '' Eriophyes canestrinii'' * ''Eriophyes cerasicrumena'' , black cherry finger gall mite * '' Eriophyes chondrillae'' * '' Eriophyes condrillae'' , gall mites * '' Eriophyes crataegi'' * '' Eriophyes cupulariae'' * '' Eriophyes dentatae'' * '' Eriophyes dimocarpi'' , longan gall mite * '' Eriophy ...

Vitis Vinifera
''Vitis vinifera'', the common grape vine, is a species of flowering plant, native to the Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. There are currently between 5,000 and 10,000 varieties of ''Vitis vinifera'' grapes though only a few are of commercial significance for wine and table grape production. The wild grape is often classified as ''Vitis vinifera'' ''sylvestris'' (in some classifications considered ''Vitis sylvestris''), with ''Vitis vinifera'' ''vinifera'' restricted to cultivated forms. Domesticated vines have hermaphrodite flowers, but ''sylvestris'' is dioecious (male and female flowers on separate plants) and pollination is required for fruit to develop. Grapes can be eaten fresh or dried to produce raisins, sultanas, and currants. Grape leaves are used in the cuisine of many cultures. The fresh grapes can also be processed into juice that is fermented to make wine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grapevine Pinot Gris Virus
''Grapevine Pinot gris virus'' (GPGV) is a positive sense single-stranded RNA virus in the genus ''Trichovirus''. It affects the growth of grapevine plants' leaves and fruit, and is similar to grapevine berry inner-necrosis virus. History Vineyards in northwest Italy began noticing symptoms of GPGV in 2003. The first two vineyards affected were Piana Rotaliana and Collio in Trentino Alto Adige. From there the virus spread to vineyards throughout Trentino Alto Adige and Friuli Venezia Giulia, then Emilia Romagna and Veneto. The virus was first identified on Pinot gris grapevines, hence the name, but soon spread to other varieties. In 2011, Annalisa Giampetruzzi et al. published an article in the journal ''Virus Research'' officially identifying and naming the virus.Giampetruzzi, Annalisa, et al. “A New Grapevine Virus Discovered by Deep Sequencing of Virus- and Viroid-Derived Small RNAs in Cv Pinot Gris”.

Tydeus Eriophyes
''Tydeus eriophyes'' is a species of mite belonging to the family Tydeidae. This small oval, eyeless mite is around 300 μm in length with a soft body covered in striations. It can be distinguished from similar species by the bluntly pointed, rod-like dorsal setae. This species is associated with the gall mite ''Eriophyes vitis'' on grapevines in the vicinity of Grabouw, South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countri ....

Grabouw
Grabouw is a town located in the Western Cape province of South Africa. Grabouw is located some 65 km south-east of Cape Town, over Sir Lowry's Pass from Somerset West, along the N2 highway.The town is the commercial centre for the vast Elgin Valley, the largest single export fruit-producing area in Southern Africa, which extends between the Hottentots-Holland, Kogelberg, Groenland, and Houwhoek Mountains. The town's population has grown rapidly, with 44 593 people in 2019 from 21 593 as listed by the 2001 census. History Pre-colonial history The original inhabitants of the area were the Khoikhoi pastoralists and the San hunter gatherers. The indigenous people of the region, the Chainouqua Khoi, inhabited a large area on both sides of the Hottentots Holland Mountains. They traded with early European settlers, but were later dispossessed from their lands by the Dutch colonists, who began to move into the area in the late 1600s and took the Chainouqua land for farming.

Eriophyidae
Eriophyidae is a family of more than 200 genera of mites, which live as plant parasites, commonly causing galls or other damage to the plant tissues and hence known as gall mites. About 3,600 species have been described, but this is probably less than 10% of the actual number existing in this poorly researched family. They are microscopic mites and are yellow to pinkish white to purplish in color. The mites are worm like, and have only two pairs of legs. Their primary method of population spread is by wind. They affect a wide range of plants, and several are major pest species causing substantial economic damage to crops. Some species, however, are used as biological agents to control weeds and invasive plant species. Notable species Notable species in this family include: *''Abacarus hystrix'', the cereal rust mite *'' Abacarus sacchari'', the sugarcane rust mite *'' Acalitus essigi'', the redberry mite, which affects blackberries *''Aceria chondrillae'', the chondrilla gall ...

Animals Described In 1857
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

Leaf Diseases
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light en ...

Grape Pests
A grape is a fruit, botanically a berry (botany), berry, of the deciduous woody vines of the flowering plant genus ''Vitis''. Grapes are a non-Climacteric (botany), climacteric type of fruit, generally occurring in clusters. The cultivation of grapes began perhaps 8,000 years ago, and the fruit has been used as human food over history. Eaten fresh or in dried form (as raisins, Zante currant, currants and Sultana (grape), sultanas), grapes also hold cultural significance in many parts of the world, particularly for their role in winemaking. Other grape-derived products include various types of jam, juice, vinegar and oil. History The Middle East is generally described as the homeland of grape and the cultivation of this plant began there 6,000–8,000 years ago. Yeast (wine), Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, leading to the discovery of alcoholic drinks such as wine.
