Aphis Genistae
''Aphis genistae'' is an aphid of the Family (biology), family Aphididae. Distribution This species can be found in most of Europe eastward to Ukraine and Turkey, and in the Nearctic realm (it has been introduced to North America). Description ''Aphis genistae'' can reach a length of . Apterae are black, coated with wax meal, while alatae have 4-8 secondary rhinaria. Biology These insects mainly feed on small branches and flowers of ''Genista anglica'', ''Genista lydia'' and ''Genista tinctoria'' (hence the species name), but they have also been collected on Laburnum, Cytisus, Petteria, Spartium and Sophora species.Wink, M.; Witte, L.Storage of quinolizidine alkaloids in Macrosiphum albifrons and Aphis genistae (Homoptera: Aphididae), Entomol. Gener., 1991, 15, 4, 237-254/ref> These aphids sometimes have a mutualistic relationship with ants. They are holocyclic (sex is involved, leading to egg production) and oviparae.

Genista
Genista is a genus of flowering plants in the legume family Fabaceae, native to open habitats such as moorland and pasture in Europe and western Asia. They include species commonly called broom, though the term may also refer to other genera, including ''Cytisus'' and ''Chamaecytisus''. Brooms in other genera are sometimes considered synonymous with ''Genista'': ''Echinospartum'', ''Retama'', ''Spartium'', ''Stauracanthus'', and ''Ulex''. Description They are mainly deciduous shrubs and trees, often with brush-like foliage, often spiny to deter grazing, and masses of small, pea-like yellow blooms which are sometimes fragrant. Many of the species have flowers that open explosively when alighted on by an insect, the style flying through the upper seam of the keel and striking the underside of the insect, followed by a shower of pollen that coats the insect. The name of the Plantagenet royal line, which reigned in England from 1154 to 1485, is derived from this genus, being a dia ...

Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Aphididae
The Aphididae are a very large insect family in the aphid superfamily ( Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid (''Myzus persicae'') being one of the most prevalent and indiscriminate carriers. Evolution Aphids originated in the late Cretaceous about (Mya), but the Aphidinae which comprises about half of the 4700 described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya.Von Dohlen CD, Moran NA (2000) Molecular data support a rapid radiation of aphids in the Cretaceous and multiple origins of host alternation.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Nearctic Realm
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface. The Nearctic realm covers most of North America, including Greenland, Central Florida, and the highlands of Mexico. The parts of North America that are not in the Nearctic realm are Eastern Mexico, Southern Florida, coastal Central Florida, Central America, and the Caribbean islands, which, together with South America, are part of the Neotropical realm. Major ecological regions The World Wildlife Fund (WWF) divides the Nearctic into four bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." Canadian Shield The Canadian Shield bioregion extends across the northern portion of the continent, from the Aleutian Islands to Newfoundland. It includes the Nearctic's Arctic Tundra and Boreal forest ecoregions. In terms of flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Genista tinctoria'', the dyer's greenweed or dyer's broom, is a species of flowering plant in the family Fabaceae. Its other common names include dyer's whin, waxen woad and waxen wood.

Laburnum
''Laburnum'', sometimes called golden chain or golden rain, is a genus of two species of small trees in the subfamily Faboideae of the pea family Fabaceae. The species are '' Laburnum anagyroides''—common laburnum and '' Laburnum alpinum''—alpine laburnum. They are native to the mountains of southern Europe from France to the Balkans. Some botanists include a third species, ''Laburnum caramanicum'', but this native of southeast Europe and Anatolia is usually treated in a distinct genus ''Podocytisus'', more closely allied to the ''Genisteae'' (brooms). Description The ''Laburnum'' trees are deciduous. The leaves are trifoliate, somewhat like a clover; the leaflets are typically long in ''L. anagyroides'' and long in ''L. alpinum''. They have yellow pea-flowers in pendulous leafless racemes long in spring, which makes them very popular garden trees. In ''L. anagyroides'', the racemes are long, with densely packed flowers; in ''L. alpinum'' the racemes are long, but wit ...
