Aphthona Nigriscutis
''Aphthona nigriscutis'' is a root-feeding flea beetle of the genus '' Aphthona''. It is one of five ''Aphthona'' spp. that has been used in Alberta, Canada to control leafy spurge Leafy spurge may refer to several species of plant in the genus ''Euphorbia'', including: * '' Euphorbia esula'', native to central and southern Europe * ''Euphorbia virgata ''Euphorbia virgata'', commonly known as leafy spurge, wolf's milk leaf ..., an invasive plant that reduces pasture quality and degrades natural habitats. It, along with ''A. lacertosa'', is one of only two biocontrol agents thought to be effective against leafy spurge. Larvae cause the most damage to the plant by feeding on the roots. Nontarget impacts ''A. nigriscutis'' will feed on the native '' Euphorbia robusta'' Engelm, though this is thought to be acceptable as the weevil significantly reduces leafy spurge populations over time. Return of diversity following biocontrol A 14-year study documented a slight increase p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoine Casimir Marguerite Eugène Foudras
Antoine Casimir Marguerite Eugène Foudras (19 November 1783, Lyon – 13 April 1859, Lyon) was a French entomologist. He was a Member of the Société Linnéenne de Lyon. Although Eugène Foudras had to work hard to earn his living, he spent all his spare time collecting insects in various parts of France, especially Chamonix, Bresse, Dauphiné, Lyonnais and Maconnais. Having sold his insect cabinet in 1837, he was able to devote himself entirely to entomology. He specialized in ”Altisides", small Coleoptera. Many species in this group are major agricultural pest. The majority of Foudras' works remain in manuscript. His later collections were bequeathed to the Lycée du Parc The Lycée du Parc is a public secondary school located in the sixth ''Arrondissements of Lyon, arrondissement'' of Lyon, France. Its name comes from the Parc de la Tête d'Or, one of Europe's largest urban parks, which is situated nearby. It pro ... in Lyon. Publications * 1827 – ''Rapport à la So ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Aphthona
''Aphthona'' is a genus of beetle, in the leaf beetle family Chrysomelidae, native to Europe and Asia. More specifically, ''Aphthona'' are flea beetle The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily. Though m ...s, meaning they have enlarged hind legs for jumping away from potential danger. There are some 300 species known worldwide. This flea beetle genus is important because of the usefulness of some species in controlling leafy spurge, a major invasive weed in parts of western North America. Several ''Aphthona'' species have been taken from Europe and introduced into localized areas of the United States and Canada, and some success against the weed is being seen. The six species used for this purpose include ''A. abdominalis'', ''A. cyparissiae'', ''A. czwalinae'', ''A. flava'', ''A. ni ...

Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Euphorbia Robusta
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and '' Senecio''. '' Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant ('' Euphorbia m ...

Alticini
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily. Though most tribes of the Galerucinae are suspect of rampant paraphyly in the present delimitation, the Alticini seem to form a good clade. Description and ecology The adults are very small to moderately sized Chrysomelidae (i.e. among beetles in general they are on the smallish side). They are similar to other leaf beetles, but characteristically have the hindleg femora greatly enlarged. These enlarged femora allow for the springing action of these insects when disturbed. Flea beetles can also walk normally and fly. Many flea beetles are attractively colored; dark, shiny and often metallic colors predominate. Adult flea beetles feed externally on plants, eating the surface of the leaves, stems and petals. Under heavy feeding the small round hole ...
