Rivellia Decatomoides
''Rivellia'' is a genus of signal flies (insects in the family Platystomatidae). There are at least 140 described species in ''Rivellia''. Economic importance There is limited information and understanding about the juvenile stages of most signal fly species. Thirteen species of ''Rivellia'' have, however, been studied in the field of agriculture because the larvae of many of these flies are associated with both living and decaying root nodules of nitrogen-fixing legumes, such as soybean, peanuts, and pigeon pea. They can also be found on the roots or flowers of other cultivated plants like eggplant, sorghum, black locust, and ''Narcissus''.Whittington, A E (2019) The economic significance of the signal fly genus ''Rivellia'' Robineau-Desvoidy (Diptera: Platystomatidae).

Robinia Pseudoacacia
''Robinia pseudoacacia'', commonly known in its native territory as black locust, is a medium-sized hardwood deciduous tree, belonging to the tribe Robinieae of the legume family Fabaceae. It is endemic to a few small areas of the United States, but it has been widely planted and naturalized elsewhere in temperate North America, Europe, Southern Africa and Asia and is considered an invasive species in some areas. Another common name is false acacia, a literal translation of the specific name (''pseudo'' reek ''ψευδο-''meaning fake or false and ''acacia'' referring to the genus of plants with the same name). Description Black locust reaches a typical height of with a diameter of . It is a very upright tree with a straight trunk and narrow crown that grows scraggly with age. The dark blue-green compound leaves with a contrasting lighter underside give this tree a beautiful appearance in the wind and contribute to its grace. Black locust is a shade-intolerant species and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diptera Of Africa
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nitrogen Fixation
Nitrogen fixation is a chemical process by which molecular nitrogen (), with a strong triple covalent bond, in the air is converted into ammonia () or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or ''diazotrophy'' is an important microbials mediated process that converts dinitrogen (N2) gas to ammonia (NH3) using the nitrogenase protein complex (Nif). Nitrogen fixation is essential to life because fixed inorganic nitrogen compounds are required for the biosynthesis of all nitrogen-containing organic compounds, such as amino acids and proteins, nucleoside triphosphates and nucleic acids. As part of the nitrogen cycle, it is essential for agriculture and the manufacture of fertilizer. It is also, indirectly, relevant to the manufacture of all nitrogen chemical c ...

Narcissus (plant)
''Narcissus'' is a genus of predominantly spring flowering perennial plant, perennial plants of the amaryllis family, Amaryllidaceae. Various common names including daffodil,The word "daffodil" is also applied to related genera such as ''Sternbergia'', ''Ismene (plant), Ismene'' and ''Fritillaria meleagris''. It has been suggested that the word "Daffodil" be restricted to the wild species of the British Isles, ''N. pseudonarcissus''. narcissus, and jonquil are used to describe all or some members of the genus. ''Narcissus'' has conspicuous flowers with six petal-like tepals surmounted by a cup- or trumpet-shaped Corona (plant structure), corona. The flowers are generally white and yellow (also orange or pink in garden varieties), with either uniform or contrasting coloured tepals and corona. ''Narcissus'' were well known in ancient civilisation, both medicinally and botanically, but formally described by Carl Linnaeus, Linnaeus in his ''Species Plantarum'' (1753). The genus ...

Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain toxic lev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Robineau-Desvoidy
André Jean Baptiste Robineau-Desvoidy (1 January 1799 in Saint-Sauveur-en-Puisaye – 25 June 1857 in Paris) was a French physician and entomologist specialising in the study of Diptera (flies) and to some extent of the Coleoptera (beetles). Achievements Because he worked on difficult to identify flies (specifically the Schizophora), the existing descriptions of which were poor, and because he had few contacts, many of the new species he described were already named. Also he was over reliant on colour and pattern as characters, and this led to his improperly defining species. He also worked on too many species. Much later criticism ensued but it must be remembered that he was an early worker and, in the aftermath of the Napoleonic Wars, French scientists were unduly criticised for nationalistic reasons. Very many of his generic and species names survive. In all these respects, as well as his genuine love of entomology and boundless enthusiasm, Robineau-Desvoidy is remini ...

Eggplant
Eggplant ( US, Canada), aubergine ( UK, Ireland) or brinjal (Indian subcontinent, Singapore, Malaysia, South Africa) is a plant species in the nightshade family Solanaceae. ''Solanum melongena'' is grown worldwide for its edible fruit. Most commonly purple, the spongy, absorbent fruit is used in several cuisines. Typically used as a vegetable in cooking, it is a berry by botanical definition. As a member of the genus ''Solanum'', it is related to the tomato, chili pepper, and potato, although those are of the New World while the eggplant is of the Old World. Like the tomato, its skin and seeds can be eaten, but, like the potato, it is usually eaten cooked. Eggplant is nutritionally low in macronutrient and micronutrient content, but the capability of the fruit to absorb oils and flavors into its flesh through cooking expands its use in the culinary arts. It was originally domesticated from the wild nightshade species ''thorn'' or ''bitter apple'', '' S. incanum'',Tsao ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
