Nasonovia Ribisnigri
''Nasonovia ribisnigri'' is a species of aphid. Their primary hosts are currant plants, including blackcurrants (''Ribes nigrum'') and gooseberries (''Ribes uva-crispa''), while the secondary hosts are a wider range of plants, including members of the Compositae (''Hieracium'', ''Lapsana'', ''Crepis'', ''Leontodon'', ''Lactuca'' and '' Cichorium''), Lamiales ('' Veronica'' and ''Euphrasia'') and Solanaceae ('' Nicotiana'' and ''Petunia''). They are an important agricultural pest in lettuce and endive cultivation.

Crepis
''Crepis'', commonly known in some parts of the world as hawksbeard or hawk's-beard (but not to be confused with the related genus ''Hieracium'' with a similar common name), is a genus of annual and perennial flowering plants of the family Asteraceae superficially resembling the dandelion, the most conspicuous difference being that ''Crepis'' usually has branching scapes with multiple heads (though solitary heads can occur). The genus name ''Crepis'' derives from the Greek ''krepis'', meaning "slipper" or "sandal", possibly in reference to the shape of the fruit.''Crepis''. Flora of North America. The genus is distributed throughout the Northern Hemisphere and |

Viviparity
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large vitellus, yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients b ...

Endive
Endive () is a leaf vegetable belonging to the genus ''Cichorium'', which includes several similar bitter-leafed vegetables. Species include '' Cichorium endivia'' (also called endive), ''Cichorium pumilum'' (also called wild endive), and ''Cichorium intybus'' (also called common chicory). Common chicory includes types such as radicchio, puntarelle, and Belgian endive. There is considerable confusion between ''Cichorium endivia'' and ''Cichorium intybus''. ''Cichorium endivia'' There are two main varieties of cultivated ''C. endivia'' chicon: * Curly endive, or frisée (var ''crispum''). This type has narrow, green, curly outer leaves. It is sometimes called chicory in the United States and is called ''chicorée frisée'' in French. Further confusion results from the fact that frisée also refers to greens lightly wilted with oil. * Escarole, or broad-leaved endive (var ''latifolia''), has broad, pale green leaves and is less bitter than the other varieties.

Lettuce
Lettuce (''Lactuca sativa'') is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce (asparagus lettuce), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. , world production of lettuce and chicory was 27 million tonnes, 56percent of which came from China. Lettuce was originally farmed by the ancient Egyptians, who transformed it from a plant whose seeds were used to obtain oil into an important food crop raised for its succulent leav ...

Petunia
''Petunia'' is genus of 20 species of flowering plants of South American origin. The popular flower of the same name derived its epithet from the French, which took the word ''petun'', meaning "tobacco," from a Tupi–Guarani language. A tender perennial, most of the varieties seen in gardens are hybrids ( ''Petunia'' × ''atkinsiana'', also known as ''Petunia'' × ''hybrida''). Taxonomy ''Petunia'' is a genus in the family Solanaceae, subfamily Petunioideae. Well known members of Solanaceae in other subfamilies include tobacco (subfamily Nicotianoideae), and the cape gooseberry, tomato, potato, deadly nightshade and chili pepper (subfamily Solanoideae). Some botanists place the plants of the genus '' Calibrachoa'' in the genus ''Petunia'', but this is not accepted by others. ''Petchoa'' is a hybrid genus derived from crossing ''Calibrachoa'' and ''Petunia''. Species Species include: Ecology Petunias are generally insect pollinated, with the exception of '' P. exserta'', w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solanaceae
The Solanaceae , or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida ( dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology. The name Solanaceae derives from the genus ''Solanum''. The etymology of the Latin word is unclear. The name may come from a perceived resemblance of certain solanaceous flowers to the sun and its rays. At least one species of ''Solanum'' is known as the "sunberry". Alternatively, the name could originate from the Latin verb ''sol ...

Euphrasia
''Euphrasia'', or eyebright, is a genus of about 450 species of herbaceous flowering plants in the family Orobanchaceae (formerly included in the Scrophulariaceae), with a cosmopolitan distribution. They are semi-parasitic on grasses and other plants. The common name refers to the plant's use in treating eye infections. Many species are found in alpine or sub-alpine meadows where snow is common. Flowers usually are borne terminally, are zygomorphic, and have a lower petal shaped like a lip. The most common flower colours are purple, blue-white, and violet. Some species have yellow markings on the lower petal to act as a guide to pollinating insects. Alternative names, mainly in herbalism, are ''Augentrostkraut, Euphrasiae herba, Herba Euphrasiae'' and ''Herbe d'Euphraise''. Use in herbalism and medicine The plant was known to classical herbalists, but then was not referred to until mentioned again in 1305. Nicholas Culpeper assigned it to the Zodiac sign Leo, claiming that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veronica (plant)
''Veronica'' is the largest genus in the flowering plant family Plantaginaceae, with about 500 species. It was formerly classified in the family Scrophulariaceae. Common names include speedwell, bird's eye, and gypsyweed. Taxonomy for this genus is currently being reanalysed, with the genus '' Hebe'' and the related Australasian genera '' Derwentia'', ''Detzneria'', ''Chionohebe'', ''Heliohebe'', ''Leonohebe'' and ''Parahebe'' now included by many botanists. Monophyly of the genus is supported by nuclear ribosomal internal transcribed spacer (ITS) and cpDNA. The taxa of the genus are herbaceous annuals or perennials, and also subshrubs, shrubs or small trees if ''Hebe'' is included. Most of the species are from the temperate Northern Hemisphere, though with some species from the Southern Hemisphere; ''Hebe'' is mostly from New Zealand. Taxonomy The genus name ''Veronica'' used in binomial nomenclature was chosen by Carl Linnaeus based on preexisting common usage of the name v ...
