Tetranychus Urticae
''Tetranychus urticae'' (common names include red spider mite and two-spotted spider mite) is a species of plant-feeding mite generally considered to be a pest. It is the most widely known member of the family Tetranychidae or spider mites. Its genome was fully sequenced in 2011, and was the first genome sequence from any chelicerate. Distribution ''T. urticae'' was originally native only to Eurasia, but has acquired a cosmopolitan distribution. Description ''T. urticae'' is extremely small, barely visible with the naked eye as reddish or greenish spots on leaves and stems; the adult females measure about long. The red spider mite, which can be seen in greenhouses and tropical and temperate zones, spins a fine web on and under leaves. Ecology This spider mite is extremely polyphagous; it can feed on hundreds of plants, including most vegetables and food crops – such as peppers, tomatoes, potatoes, pepinos, beans, maize, and strawberries, and ornamental plants such a ...

Léon Jean Marie Dufour
Léon Jean Marie (or Jean-Marie Léon) Dufour (10 April 1780, Saint-Sever – 18 April 1865) was a French medical doctor and naturalist. Between 1799 and 1806 he studied medicine in Paris then returned to Saint-Sever in the Landes. He participated as an army doctor in the Peninsular War and returned to his birthplace at the end of the war. In 1854, he was elected a foreign member of the Royal Swedish Academy of Sciences. Dufour’s gland, an abdominal gland found in the females of nearly all members of the suborder Apocrita, is named after him. During his life he published 232 articles on arthropods (twenty on spiders) and was the author of ''Recherches anatomiques sur les Carabiques et sur plusieurs autres Coléoptères'' (1824–1826, Paris). He was honoured in 1810, in the naming of ''Dufourea'', which is a genus of lichen-forming fungi in the subfamily Xanthorioideae of the family Teloschistaceae.

Spider Mite
Spider mites are members of the Tetranychidae family, which includes about 1,200 species. They are part of the subclass Acari (mites). Spider mites generally live on the undersides of leaves of plants, where they may spin protective silk webs, and they can cause damage by puncturing the plant cells to feed. Spider mites are known to feed on several hundred species of plants. Description Spider mites are less than in size and vary in color. They lay small, spherical, initially transparent eggs and many species spin silk webbing to help protect the colony from predators; they get the "spider" part of their common name from this webbing. Life cycle Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One female can lay up to 20 eggs per day and can live for 2 to 4 weeks, laying hundred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetranychus Lintearius
''Tetranychus lintearius'' is a species of spider mite known as the gorse spider mite. It is used as an agent of biological pest control on common gorse, a noxious weed in some countries. The adult mite is half a millimeter long and bright red. It lives in colonies in a shelter of spun silk spanning many branch tips. Infested plants are easily identifiable by these cobweb-like sheets of silk, which can grow quite large. The female lays one to four eggs per day during her three- to four-week adult lifespan. The tiny nymph is small enough to disperse on the wind during its first stage. Those that stay behind populate the colony as it expands. This mite is native to Europe, where it does more damage to the plant than any other organism. The mite appears to be host-specific; it does not attack any other plants. The adult and nymph damage the plant by piercing its tissues during feeding. Heavy mite activity reduces flowering and can stunt the development of the branches. It is widesp ...

Invasive Species Compendium
The Invasive Species Compendium (ISC) is an online, open access reference work covering recognition, biology, distribution, impact, and management of invasive plants and animals produced by CAB International alongside an international consortium. It comprises peer-reviewed datasheets, images, and maps, a bibliographic database, and full text articles. New datasheets, data sets, and scientific literature are added on a weekly basis. The ISC has been resourced by a diverse international consortium of government departments, non-governmental organizations, and private companies. Coverage The Invasive Species Compendium currently covers over 1,500 species with over 7,000 basic summary datasheets and 1,500 detailed datasheets. In addition, it provides access to over 1,100 full text articles (in PDF Portable Document Format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independen ...

Centre For Agriculture And Bioscience International
CABI (legally CAB International, formerly Commonwealth Agricultural Bureaux) is a nonprofit intergovernmental development and information organisation focusing primarily on agricultural and environmental issues in the developing world, and the creation, curation, and dissemination of scientific knowledge. Overview CABI is an international not-for-profit organisation. Their work is delivered through teams of CABI scientists and key partners working in over 40 countries across the world. CABI states its mission as "improving people’s lives worldwide by solving problems in agriculture and the environment". These problems include loss of crops caused by pests and diseases, invasive weeds and pests that damage farm production and biodiversity, and lack of global access to scientific research. Funding CABI states that only 3% of its revenue comes from core funding. Donors listed in the company's 2014 financial report include the UK's Department for International Development ( ...

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 and 25,821 species, and there were another 10 species with 24 species that present only as fossils. These 151 ...
