Aculops Rhois
''Aculops rhois'', the poison ivy gall mite, is a species of Eriophyid mite found in North America. They form galls in poison ivy as well as other members of North American '' Toxicodendron'' and some species of ''Rhus'' (including fragrant sumac). Identification Poison ivy gall mites form small red pouch galls on the upper surface of the leaves of their host. The mites themselves are extremely small and are usually found in the interior of the pouch (on the underside). The bright coloration they create in their host plant, however, makes this species fairly conspicuous and easy to detect compared to other members of ''Aculops'' (such as ''Aculops ailanthii ''Aculops ailanthii'', the Ailanthus leafcurl mite, is a species of eriophyid mite that infects trees-of-heaven ('' Ailanthus altissima''). Very little is known about this species. ''A. ailanthii'' has been proposed as a potential biocontrol alon ...'' in trees-of-heaven). Due to this, this species is one of the more wide ...

Eriophyid
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 m ...

Toxicodendron
''Toxicodendron'' is a genus of flowering plants in the sumac family, Anacardiaceae. It contains trees, shrubs and woody vines, including poison ivy, poison oak, and the lacquer tree. All members of the genus produce the skin-irritating oil urushiol, which can cause a severe allergic reaction. The generic name is derived from the Greek words τοξικός (''toxikos''), meaning "poison," and δένδρον (''dendron''), meaning "tree". The best known members of the genus in North America are poison ivy ''(T. radicans)'', practically ubiquitous throughout most of eastern North America, and western poison oak ('' T. diversilobum''), similarly ubiquitous throughout much of the western part of the continent. The genus is a member of the ''Rhus complex'', and has at various times been categorized as being either its own genus or a sub-genus of ''Rhus.'' There is evidence which points to keeping ''Toxicodendron'' as a separate monophyletic genus, but researchers have stated tha ...

Rhus
Sumac ( or ), also spelled sumach, is any of about 35 species of flowering plants in the genus ''Rhus'' and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout the world, including East Asia, Africa, and North America. Sumac is used as a spice, as a dye, and in medicine. Description Sumacs are dioecious shrubs and small trees in the family Anacardiaceae that can reach a height of . The leaves are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes long, each flower very small, greenish, creamy white or red, with five petals. The fruits are reddish, thin-fleshed drupes covered in varying levels of hairs at maturity and form dense clusters at branch tips, sometimes called sumac bobs. Sumacs propagate both by seed ( spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies. T ...

Rhus Aromatica
''Rhus aromatica'', the fragrant sumac, is a deciduous shrub in the family Anacardiaceae native to North America.(1) (2) It is found in southern Canada (Alberta to Quebec) and nearly all of the lower 48 states except peninsular Florida. Fragrant sumac is a woody plant with a rounded form that grows to around to tall and to wide. The plant develops yellow flowers in clusters on short lateral shoots in March through May. The flower is a small, dense inflorescence that usually opens before the plant's leaves do. The species is polygamodioecious (mostly dioecious, primarily bearing flowers of only one sex, but with either a few flowers of the opposite sex or a few bisexual flowers on the same plant). Male (staminate) flowers develop in yellowish catkins, while female (pistillate) flowers develop in short bright yellow panicles at the ends of branches. Pollinated flowers develop clusters of to hairy red drupes containing a single nutlet during June through August. The fru ...

Aculops
''Aculops'' is a genus of mites that belongs to the family Eriophyidae that live as plant parasites. Some species, such as ''Aculops lycopersici'', are severe crop or ornamental pests, while ''Aculops ailanthii'' is being considered as biocontrol for the extremely invasive tree-of-heaven in North America. Very little is known about this genus, with new species constantly being discovered even in well covered regions such as New Zealand. Selected species *''Aculops ailanthii'' (Lin-Fuping, Jin-Changle & Kuang-Haiyua, 1997) - ailanthus leafcurl mite *''Aculops cannabicola'' (Farkas, 1960) – hemp russet mite *''Aculops fuchsiae'' (Keifer, 1972) – fuchsia gall mite *''Aculops lycopersici'' (Massee, 1937) – tomato russet mite *''Aculops rhois'' (Stebbins, 1909) - poison ivy gall mite *''Aculops tetanothrix'' (Nalepa, 1889) – willow gall mite References External links * * Eriophyidae Trombidiformes genera {{Trombidiformes-stub ...

Aculops Ailanthii
''Aculops ailanthii'', the Ailanthus leafcurl mite, is a species of eriophyid mite that infects trees-of-heaven ('' Ailanthus altissima''). Very little is known about this species. ''A. ailanthii'' has been proposed as a potential biocontrol alongside ailanthus webworms and mimosa wilt ('' Fusarium oxysporum'') in North America, where ''Ailanthus'' is a severe invasive. Identification Infections by this species can be found by the changes it makes to the leaves of ''A. altissima''. Compared to healthy leaves, leaves infected by ''A. ailanthii'' have somewhat undercurled, wrinkled and somewhat glossier. This can be difficult to detect compared to the conspicuous galls made by many other members of 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 l ..., possibly contributing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree-of-heaven
''Ailanthus altissima'' , commonly known as tree of heaven, ailanthus, varnish tree, or in Chinese as ''chouchun'' (), is a deciduous tree in the family Simaroubaceae. It is native to northeast and central China, and Taiwan. Unlike other members of the genus ''Ailanthus'', it is found in temperate climates rather than the tropics. The tree grows rapidly, and is capable of reaching heights of in 25 years. While the species rarely lives more than 50 years, some specimens exceed 100 years of age. Its suckering ability allows this tree to clone itself indefinitely. It is considered a noxious weed and vigorous invasive species, and one of the worst invasive plant species in Europe and North America. In 21st-century North America, the invasiveness of the species has been compounded by its harboring of the also destructive and invasive spotted lanternfly.
