Onion Fly
''Delia antiqua'', commonly known as the onion fly, is a cosmopolitan distribution, cosmopolitan Pest (organism), pest of crops. The larvae or maggots feed on onions, garlic, and other bulbous plants. Morphology and biology The onion fly has an ash-grey body and resembles a housefly. The male has a longitudinal stripe on the abdomen which is lacking in the female. The legs are black, the wings transparent, and the compound eyes brown. The Egg (biology), eggs are white and elongated and are laid in groups on the shoots, leaves, and bulbs of host plants and on the ground nearby. The larvae are white and cylindrical and hatch in 3 to 8 days. Each batch of larvae tends to keep together and collectively create large cavities in bulbs. More than 50 maggots may feed on one bulb, sometimes originating from eggs laid by several females. The larvae moult three times, feed for about 20 days, and grow to about 1.0 cm long. The pupa is brown, ringed, and ovoid and measures long. Pupatio ...

The edible part of the plant is a bundle of Leaf sheath, leaf sheaths that is sometimes erroneously called a "stem" or "stalk". The genus ''Allium'' also contains the onion, garlic, shallot, scallion, chives, and Allium chinense, Chinese onion. Three closely related vegetables—elephant garlic, kurrat and Persian leek or ''tareh''—are also cultivars of ''A. ampeloprasum'', although different in their culinary uses. Etymology Historically, many scientific names were used for leeks, but they are now all treated as cultivars of ''A. ampeloprasum''. The name ''leek'' developed from the Old English word , from which the modern English name for garlic also derives. means 'onion' in Old English and has cognates in other Germanic languages: Danish ' 'onion', Icelandic ' 'onion', Norwegian ' 'onion', Swedish ' 'onion', German ' 'leek', Dutch ' '' ...

Institut National De La Recherche Agronomique
The Institut national de la recherche agronomique (; ; abbr. INRA ) was a French public research institute dedicated to agricultural science. It was founded in 1946 and is a Public Scientific and Technical Research Establishment under the joint authority of the Ministries of Research and Agriculture. From 1 January 2020 the INRA merged with the IRSTEA ( Institut national de recherche en sciences et technologies pour l'environnement et l'agriculture) to create the INRAE ( Institut national de recherche pour l'agriculture, l'alimentation et l'environnement). INRA led projects of targeted research for a sustainable agriculture, a safeguarded environment and a healthy and high quality food. Based on the number of publications in agricultural sciences/crops and animal sciences, INRA was the first institute for agricultural research in Europe, and the second in the world. It belonged to the top 1% most cited research institutes. Missions INRA main tasks were: * to gather and dissemi ...

Insects Described In 1826
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ...

Agricultural Pest Insects
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats and cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being ro ...

Anthomyiidae
The Anthomyiidae are a large and diverse family (biology), family of Muscoidea fly, flies. Most look rather like small houseflies. Most species are drab grey to black. Many ''Pegomya'' are yellow, and some members of the genus, genera ''Anthomyia'' and ''Eutrichota'' are patterned in black-and-white or black-and-silvery-grey. Most are difficult to identify, apart from a few groups such as the Kelp fly, kelp flies that are conspicuous on beaches. The name Anthomyiidae was derived from Greek ''anthos'' (flower) plus ''myia'' (a fly). Some species are commonly called "root-maggots", as the larvae are found in the stems and roots of various plants. As larvae, some also feed on decaying plant material. The well-known grey "seaweed flies" or "kelp flies" (''Fucellia'') are examples. Others are scavengers in such places as birds' nests; yet other species are leaf miners; the family also includes inquilines, commensals, and parasite, parasitic larvae. Some species in the family ar ...

Seed Dressing
A seed treatment is a treatment of the seed with either chemical agents or biological or by physical methods. Usually done to provide protection to the seed and improve the establishment of healthy crops. Not to be confused with a seed coating. In agriculture and horticulture, coating of the seed is the process of applying exogenous materials to the seed. Also referred to as seed dressing. A seed coating is the layer of material added to the seed, which may or may not contain a "protectant" ( biological or chemical pesticide) or biostimulant applied to the seed and possibly some color... By the amount of material added, it can be divided into: * A Film coating, a layer of thin film applied to the seed typically less than 10% of the mass of the original seed. * Encrustment, where the applied material is typically 100%–500% of the original seed mass, but the shape is still discernible. * Pellet, where the applied material is so thick that the seed's original shape is not di ...

Shallot
The shallot is a cultivar group of the onion. Until 2010, the (French red) shallot was classified as a separate species, ''Allium ascalonicum''. The taxon was synonymized with '' Allium cepa'' (the common onion) in 2010, as the difference was too small to justify a separate species. As part of the onion genus ''Allium'', its close relatives include garlic, scallions, leeks, chives, and the Chinese onion. Etymology and names The names '' scallion'' and ''shallot'' are derived from the Old French ''eschalotte'', by way of ''eschaloigne'', from the Latin ''Ascalōnia caepa'' or Ascalonian onion, a ''Ascalōnia caepa'' or Ascalonian onion, a namesake of the ancient city of Ascalon. The term ''shallot'' is usually applied to the French red shallot (''Allium cepa'' var. ''aggregatum'', or the ''A. cepa'' Aggregatum Group). It is also used for the Persian shallot or ''musir'' (''A. stipitatum'') from the Zagros Mountains in Iran and Iraq, and the French gray shallot ('' Allium os ...

A perennial plant, ''A. schoenoprasum'' is widespread in nature across much of Eurasia and North America. It is the only species of ''Allium'' native to both the New and the Old Worlds. The leaves and flowers are edible. Chives are a commonly used herb and vegetable with a variety of culinary uses. They are also used to repel insects. Description Chives are a bulb-forming herbaceous perennial plant, growing to tall. The bulbs are slender, conical, long and broad, and grow in dense clusters from the roots. The scapes (or stems) are hollow and tubular, up to long and across, with a soft texture, although, prior to the emergence of a flower, they may appear stiffer than usual. The grass-like leaves, which are shorter than the scapes, are also hollow and tubular, or terete (round in cross-section). The flowers are pale purple, and star-shaped with si ...
