Psylla Alni
''Psylla alni'' is a species of psyllid, a plant-feeding hemipteran in the family Psyllidae. Distribution This species is present in the Palearctic realm (from Europe to Siberia and Sakhalin, Kazakhstan, Caucasus) and in the Nearctic realm (Canada and United States of America).

European Pear
''Pyrus communis'', the common pear, is a species of pear native to central and eastern Europe, and western Asia. It is one of the most important fruits of temperate regions, being the species from which most orchard pear cultivars grown in Europe, North America, and Australia have been developed. Two other species of pear, the Nashi pear (''Pyrus pyrifolia'') and the hybrid Chinese white or ya pear (''Pyrus × bretschneideri'', ) are more widely grown in East Asia. Subtaxa The following subspecies are currently accepted: *''Pyrus communis'' subsp. ''caucasica'' – Turkey, Caucasus *''Pyrus communis'' subsp. ''communis'' – Entire range except Caucasus Origin The cultivated Common pear (''P. communis'' subsp. ''communis'') is thought to be descended from two subspecies of wild pears, categorized as ''P. communis'' subsp.'' pyraster'' ( syn. ''P. pyraster'') and ''P. communis'' subsp. ''caucasica'' (syn. ''P. caucasica''), which are interfertile with domesticated pears. Arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psylla Pyri
''Psylla pyri'', commonly known as the pear psylla or pear psyllid, is an insect in the family Psyllidae. Originating in Europe and Asia, it has spread to North America. It is a pest of pear trees, sucking the sap, damaging the foliage, flowers and fruit and diminishing the crop. Description The adult ''Psylla pyri'' is between long. The colour is variable, ranging between orange-red and black, the thorax having whitish longitudinal stripes on its upper surface. The wings are transparent, with dark veins and sometimes a smoky appearance near the base. Later instar nymphs are purplish-brown or reddish-brown, with white longitudinal stripes and black patches; the developing wing-pads each bear a single knobbed bristle. The younger nymphs are yellowish with red-purple eyes. Distribution The species is found in Europe, including Scandinavia, and in Asia. In Britain it used to be very rare, with only one record before 1969, but since then it has become much more common, especially i ...

Albizia Odoratissima
''Albizia odoratissima'', a member of the family Fabaceae, is a fast-growing, deciduous tree reaching in height, a diameter of , and native to large parts of India (where it is known as கருவாகை, Kali siris or black siris), Bangladesh, Bhutan, Nepal, Myanmar, Laos, Thailand, Vietnam, Sri Lanka (where it is known as Ceylon rosewood) and China. It is one of the top nitrogen-fixing trees. The species' wide range of habitat, usefulness and rapid growth of about in height annually, has led to an extensive distribution in the tropics and occasionally in the temperate zones, despite young plants' being susceptible to frost. It has become naturalised over large swathes of Tropical Africa, extending from Kenya down the east coast through Tanzania, Malawi and Zimbabwe as far south as Mozambique, and is grown in Johannesburg, South Africa. It has also become feral in Central America and Florida in the United States. It will tolerate a wide range of soil types, but does best o ...

Tilia
''Tilia'' is a genus of about 30 species of trees or bushes, native throughout most of the temperateness, temperate Northern Hemisphere. The tree is known as linden for the European species, and basswood for North American species. In Britain and Ireland they are commonly called lime trees, although they are not related to the citrus Lime (fruit), lime. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the Cronquist system, Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae. ''Tilia'' species are mostly large, deciduous trees, reaching typically tall, with oblique-cordate (heart-shaped) leaves across. As with elms, the exact number of species is uncertain, as many of the species can Hybrid (biology), hybridise readily, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Buxus'' is a genus of about seventy species in the family Buxaceae. Common names include box or boxwood. The boxes are native to western and southern Europe, southwest, southern and eastern Asia, Africa, Madagascar, northernmost South America, Central America, Mexico and the Caribbean, with the majority of species being tropical or subtropical; only the European and some Asian species are frost-tolerant. Centres of diversity occur in Cuba (about 30 species), China (17 species) and Madagascar (9 species). They are slow-growing evergreen shrubs and small trees, growing to 2–12 m (rarely 15 m) tall. The leaves are opposite, rounded to lanceolate, and leathery; they are small in most species, typically 1.5–5 cm long and 0.3–2.5 cm broad, but up to 11 cm long and 5 cm broad in ''B. macrocarpa''.

Psylla Buxi
''Psylla buxi'', known generally as the boxwood psyllid or box sucker, is a species of plant-parasitic hemipteran in the family Psyllidae. It is native to Europe and introduced to North America. The psyllid causes cabbage-like leaf clusters, known as galls at the tips of box shoots. The leaves are slightly thicker and strongly concave, and in the summer conceal many pale green nymphs A nymph ( grc, νύμφη, nýmphē, el, script=Latn, nímfi, label=Modern Greek; , ) in ancient Greek folklore is a minor female nature deity. Different from Greek goddesses, nymphs are generally regarded as personifications of nature, are typ ..., which are coated with white wax.
