Hop Aphids
''Phorodon humuli'', the hop aphid, or damson-hop aphid, is an aphid in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap. Host plants Hop aphids are hosted by different plants in summer and winter. In winter, they are known to be hosted by ''Prunus'' sp. such as, ''Prunus domestica'', ''Prunus spinosa'', ''Prunus padus'', and ''Prunus cerasifera''. During summer, they are hosted by ''Humulus lupulus'', ''Humulus japonicus'', and ''Urtica dioica ''Urtica dioica'', often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae.

Aphid
Aphids are small sap-sucking insects in the Taxonomic rank, family Aphididae. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white Eriosomatinae, woolly aphids. A typical life cycle involves flightless females giving Viviparity, live birth to female Nymph (biology), nymphs—who may also be already Pregnancy, pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Developmental biology, Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Alate, Winged females may develop later in the season, allowing the insects to colonize new plants. In Temperate climate, 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 ...

Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising more than 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is sometimes limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some varieties of English, all terrestrial arthropods (including non-insect arachnids and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. ...

Prunus
''Prunus'' is a genus of flowering plant, flowering trees and shrubs from the family (biology), family Rosaceae. The genus includes plums, cherries, peaches, nectarines, apricots and almonds (collectively Drupe, stonefruit). The genus has a cosmopolitan distribution, being native to the temperate regions of North America, the neotropics of South America, and temperate and tropical regions of Eurasia and Africa, There are about 340 accepted species . Many members of the genus are widely cultivated for their sweet, fleshy fruit and for decorative purposes of their flowers. ''Prunus'' fruit are drupes, or stone fruits. The fleshy Fruit anatomy, mesocarp surrounding the Fruit anatomy, endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel"), which is edible in some species (such as sweet almonds), but poisonous in many others (such as apricot kernels). Besides being eaten off the hand, m ...

Prunus Domestica
''Prunus domestica'' is a species of flowering plant in the family Rosaceae. A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species. The greengages and damsons also belong to subspecies of ''P. domestica''. Description It typically forms a large shrub or a small tree. It may be somewhat thorny, with white blossom, borne in early spring. The oval or spherical fruit varies in size, but can be up to across. The pulp is usually sweet, but some varieties are sour. Like all ''Prunus'' fruits, it contains a single large seed, usually called a stone, which is discarded when eating. Taxonomy The species' hybrid parentage was believed to be '' Prunus spinosa'' and '' P. cerasifera''; however, recent cytogenetic evidence seem to implicate 2×, 4×, 6× ''P. cerasifera'' as the sole wild stock from which the cultivated 6× ''P. domestica'' could have evolved.

Prunus Spinosa
''Prunus spinosa'', called blackthorn or sloe, is an Old World species of flowering plant in the rose family, Rosaceae. It is locally naturalized in parts of the New World. The fruits are used to make sloe gin in Britain and patxaran in Basque Country. The wood is used to make walking sticks, including the Irish shillelagh. Description ''Prunus spinosa'' is a large deciduous shrub or small tree growing to tall, with blackish bark and dense, stiff, spiny branches. The leaves are oval, long and broad, with a serrated margin. The flowers are about in diameter, with five creamy-white petals; they are produced shortly before the leaves in early spring, and are hermaphroditic, and insect-pollinated. The fruit, called a "sloe", is a drupe in diameter, black with a purple-blue waxy bloom, ripening in autumn and traditionally harvested – at least in the UK – in October or November, after the first frosts. Sloes are thin-fleshed, with a very strongly astringent flavour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Padus

Humulus Lupulus
''Humulus lupulus'', the common hop or hops, is a species of flowering plant in the hemp family, Cannabaceae. It is a perennial, herbaceous climbing plant which sends up new shoots in early spring and dies back to a cold-hardy rhizome in autumn. It is dioecious (having separate male and female plants) and native to West Asia, Europe and North America. As the female cone-shaped flowers (hops) are used to preserve and flavor beer, the species is widely cultivated for the brewing industry. Description ''Humulus lupulus'' is a perennial herbaceous plant up to tall, living up to 20 years. It has simple leaves with 3–5 deep lobes that can be opposite or alternate. The species is triggered by the longer summer days to flower, usually around July or August in the Northern Hemisphere. The plant is dioecious, with male and female flowers on separate plants. The fragrant flowers are wind-pollinated. The staminate (male) flowers do not have petals, while the pistillate (female) flowers ...

Humulus Japonicus
''Humulus japonicus'', known as Japanese hops, is an ornamental plant in the family Cannabaceae. Some authorities have it as a synonym of ''Humulus scandens''. Originally native to East Asian countries such as China, Japan, Korea, and extending its habitat to Vietnam, it was imported to North America in the late 19th century as an ornamental. Since its arrival in North America, it has spread widely. It can be found throughout the Northeastern U.S. and eastern Canada, and considered an invasive species in North America. It also features on the list of invasive alien species of Union Concern since 2019. This means it can no longer be imported in the European Union. Additionally, it has become illegal to plant it, breed it, transport it, or bring it into the wild in all Member States. Nomenclature ''Humulus japonicus'' (syn. ''H. scandens'', ''Antidesma scandens'') is known by the common name of "Asian hop","Japanese hop", or "wild hop". The plant is called ''lü cao'' ( zh, t=� ...

Urtica Dioica
''Urtica dioica'', often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact ("contact urticaria", a form of contact dermatitis). The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient (such as Saxon) and modern societies. Description ''Urtica dioica'' is a dioecious, herbaceous, and perennial plant. It grows to tall in the summer and dying down to the ground in winter. It has widely spread ...
