Ophiomyia Simplex
The asparagus miner (''Ophiomyia simplex'' Loew; Diptera; Agromyzidae) is a Generalist and specialist species, specialist insect that lives on asparagus plants (''Asparagus officinalis'' L.) and is a problem for asparagus growers. It is shiny black and occurs in most major asparagus-producing regions of the world. Identification The asparagus miner is a bivoltine stem-mining fly and a major pest of asparagus. It is small (~2–5 mm) with a shiny black body and black legs Under a dissecting microscope or with a hand lens, one can confirm the identity of the fly by checking that the costa (the thicker marginal vein) ends at vein R4+5. In addition, the fly has five conspicuous orbital bristles emerging from the middle of its head. The maggots (immature stages) may be up to 5 mm long, and can be found feeding internally in asparagus stems. They are creamy white in appearance, with the anterior spiracles on short stalks. The pupae are darker brown or reddish, and can somet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Loew
Friedrich Hermann Loew (19 July 1807 – 21 April 1879) was a German entomologist who specialised in the study of Diptera, an order of insects including flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States. Biography Early years Hermann Loew was born in Weissenfels, Saxony a short distance south of Halle (Germany). The Loew family, though not wealthy, was well-placed. Loew's father was a functionary for the Department of Justice of the Duchy of Saxony who later became a ''Geheimer Regierungsrath'' of Prussia. Between 1817 and 1829 Loew attended first the Convent school of Rossleben, then the University of Halle-Wittenberg, graduating in mathematics, philology and natural history. Teacher, tutor and husband Recognizing his abilities as a mathematician, the university, on his graduation, appointed him as a lecturer in the same subjects. In 1830 he went to Berlin and gave lessons in differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tschirnhaus
Ehrenfried Walther von Tschirnhaus (or Tschirnhauß, ; 10 April 1651 – 11 October 1708) was a German mathematician, physicist, physician, and philosopher. He introduced the Tschirnhaus transformation and is considered by some to have been the inventor of European porcelain, an invention long accredited to Johann Friedrich Böttger but others claim porcelain had been made by English manufacturers at an even earlier date. Biography Von Tschirnhaus was born in Kieslingswalde (now Sławnikowice in western Poland) and died in Dresden, Saxony. Education Von Tschirnhaus attended the Gymnasium at Görlitz. Thereafter he studied mathematics, philosophy, and medicineSee Jacob Adler, "The Education of Ehrenfried Walther von Tschirnhaus (1651–1708)," ''Journal of Medical Biography'' 23(1) (2015): 27-35 at the University of Leiden. He traveled considerably in France, Italy, and Switzerland, and served in the army of Holland (1672–1673). During his travels he met Baruch ...

Generalist And Specialist Species
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food), others less so, and some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species. Description Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asparagus
Asparagus, or garden asparagus, folk name sparrow grass, scientific name ''Asparagus officinalis'', is a perennial flowering plant species in the genus ''Asparagus''. Its young shoots are used as a spring vegetable. It was once classified in the lily family, like the related ''Allium'' species, onions and garlic. However, genetic research places lilies, ''Allium'', and asparagus in three separate families—the Liliaceae, Amaryllidaceae, and Asparagaceae, respectively— the Amaryllidaceae and Asparagaceae are grouped together in the order Asparagales. Sources differ as to the native range of ''Asparagus officinalis'', but generally include most of Europe and western temperate Asia. It is widely cultivated as a vegetable crop. Description Asparagus is a herbaceous, perennial plant growing to tall, with stout stems with much-branched, feathery foliage. The 'leaves' are in fact needle-like cladodes ( modified stems) in the axils of scale leaves; they are long and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fusarium In Asparagus Mine
''Fusarium'' is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts ...

Agromyzidae
The Agromyzidae are a family commonly referred to as the leaf-miner flies, for the feeding habits of their larvae, most of which are leaf miners on various plants. A worldwide family of roughly 2,500 species, they are small, some with wing length of 1 mm. The maximum size is 6.5 mm. Most species are in the range of 2 to 3 mm. General description Adult agromyzids can be recognized by the distinctive sclerotization of the head. The upper part of the frons, above the ptilinal suture (known as the frontal vitta) is lightly sclerotized and lacks setae, while the lower part of the frons and the dorsal area of the head tends to be much more heavily sclerotized and setaceous. Thus, the frontal vitta often forms a distinctive patch on the head, different in colour and texture from the rest of the head. The compound eyes are usually oval and fairly small, although in some species, they are larger and more circular. The wings are usually hyaline, although those of a few ...

Agricultural Pest Insects
A pest is any animal or plant 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; 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 cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera Of North America
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] |
