Sepedomerus Macropus
''Sepedomerus macropus'', the liverfluke snail predator fly, is a species of marsh fly native to the American tropics and subtropics. Larvae of this species are predators of lymnaeid pond snails, which are vectors of the liver fluke '' Fasciola gigantica''. ''S. macropus'' has been introduced to tropical regions outside the Americas (Hawaii, Guam, Thailand) for the purpose of reducing numbers of lymnaeid snails as a public health measure. In Hawaii, introduced ''S. macropus'' have become a threat to the survival of native lymnaeid snail species, including the endangered Newcomb's snail Newcomb's snail (''Erinna newcombi'') is a species of air-breathing freshwater snail, a gastropod mollusk in the family Lymnaeidae. This species is endemic to Hawaii, in the United States. Its natural habitat is rivers. It is threatened by habi ....

Francis Walker (entomologist)
Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it “It is to him raythat the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, the publication of which beg ...

Frederik Maurits Van Der Wulp
Frederik Maurits van der Wulp (13 December 1818, The Hague – 27 November 1899, The Hague) was a Dutch entomologist mainly interested in Diptera. He was a civil servant in the Dutch Audit Office. His collection is divided between Natura Artis Magistra in Amsterdam and Rijksmuseum van Natuurlijke Historie in Leiden. Frederik van der Wulp was a Member of the Netherlands Entomological Society.

Sciomyzidae
The family Sciomyzidae belongs to the typical flies (Brachycera) of the order Diptera. They are commonly called marsh flies, and in some cases snail-killing flies due to the food of their larvae. Here, the Huttoninidae, Phaeomyiidae and Tetanoceridae are provisionally included in the Sciomyzidae. Particularly the latter seem to be an unequivocal part of this group and are ranked as tribe of subfamily Sciomyzinae by most modern authors, while the former two are very small lineages that may or may not stand outside the family and are provisionally ranked as subfamilies here. Whether the Salticellinae and the group around ''Sepedon'' warrant recognition as additional subfamilies or are better included in the Sciomyzinae proper is likewise not yet entirely clear. Altogether, the main point of contention is the relationship between the "Huttoninidae", "Phaeomyiidae", Sciomyzidae '' sensu stricto'', and the Helosciomyzidae which were also once included in the Sciomyzidae.

Lymnaeid
Lymnaeidae, common name the pond snails, is a taxonomic family of small to large air-breathing freshwater snails, aquatic pulmonate gastropod mollusks, that belong to the clade Hygrophila. Lymnaeidae is the only family within the superfamily Lymnaeoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Taxonomy 2005 taxonomy Bouchet & Rocroi (2005) recognized four subfamilies within Lymnaeidae: * subfamily Lymnaeinae Rafinesque, 1815 - synonyms: Amphipepleinae Pini, 1877; Limnophysidae W. Dybowski, 1903; Acellinae Hannibal, 1912; Fossariinae B. Dybowski 1913 * subfamily Lancinae Hannibal, 1914 * † subfamily Scalaxinae Zilch, 1959 * † subfamily Valencieniinae Kramberger-Gorjanovic, 1923 - synonym: Clivunellidae Kochansky-Devidé & Sliskovic, 1972 2013 taxonomy Vinarski (2013)Vinarski M.

Liver Fluke
Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. They are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and liver parenchyma. In these organs, they produce pathological lesions leading to parasitic diseases. They have complex life cycles requiring two or three different hosts, with free-living larval stages in water. Biology The body of liver flukes is leaf-like and flattened. The body is covered with a tegument. They are hermaphrodites having complete sets of both male and female reproductive systems. They have simple digestive systems and primarily feed on blood. The anterior end is the oral sucker opening into the mouth. Inside, the mouth leads to a small pharynx which is followed by an extended intestine that runs through the entire length of the body. The intestine is heavily branched and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fasciola Gigantica
''Fasciola gigantica'' is a parasitic flatworm of the class Trematoda, which causes tropical fascioliasis. It is regarded as one of the most important single platyhelminth infections of ruminants in Asia and Africa. Estimates of infection rates are as high as 80–100% in some countries. The infection is commonly called fasciolosis. The prevalence of ''F. gigantica'' often overlaps with that of ''Fasciola hepatica'', and the two species are so closely related in terms of genetics, behaviour, and morphological and anatomical structures that distinguishing them is notoriously difficult. Therefore, sophisticated molecular techniques are required to correctly identify and diagnose the infection. Distribution ''Fasciola gigantica'' causes outbreaks in tropical areas of South Asia, Southeast Asia, and Africa. The geographical distribution of ''F. gigantica'' overlaps with ''F. hepatica'' in many African and Asian countries and sometimes in the same country, although in such cases, ...

Erinna Newcombi
Newcomb's snail (''Erinna newcombi'') is a species of air-breathing freshwater snail, a gastropod mollusk in the family Lymnaeidae. This species is endemic to Hawaii, in the United States. Its natural habitat is rivers. It is threatened by habitat loss. ''Erinna newcombi'' is the type species of the genus ''Erinna''. Taxonomy The scientific collection efforts of the United States Exploring Expedition of 1838 to 1842 obtained the first known specimens of Newcomb's snails. Historical documents indicate that the specimens were collected sometime between 25 October and 6 November 1840, at " Hanapēpē Falls," presumably what is now called Manuwaiopuna Falls, or possibly one of several other waterfalls located in the middle Hanapēpē watershed of southeast Kauaʻi. Individuals from this early collection made their way to the British Museum of Natural History and were used as the type specimens from which the species was later described in 1855. As type locality is referred: "'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
