Roger Ward Crosskey
Roger Ward Crosskey (29 January 1930 - 4 September 2017) was a British entomologist who worked at the Commonwealth Institute of Entomology and at the Natural History Museum in London specializing in blackflies ( Simuliidae), Tachinidae and the hymenopteran superfamily Evanioidea. Roger Crosskey was born in Croydon to Harold and Elfreda née Ward. His mother died of cancer when he was sixteen and after that spent a lot of his time outdoors collecting insects including butterflies and diving beetles. He studied at Whitgift School and his first publication was in 1951. He studied ensign wasps ( Aulacidae and Gasteruptiidae) for his master's degree from the University of London. He married Margaret Eileen ("Peggy") née Godfrey with whom he studied at college. Peggy was also an entomologist and worked alongside him throughout his career. Crosskey joined as an entomologist in the service of the Government of Northern Nigeria to study sleeping sickness in 1951. He also studied onchoc ...

Entomology
Entomology () is the science, scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology (biology), morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. Th ...

Onchocerciasis
Onchocerciasis, also known as river blindness, is a disease caused by infection with the parasitic worm ''Onchocerca volvulus''. Symptoms include severe itching, bumps under the skin, and blindness. It is the second-most common cause of blindness due to infection, after trachoma. The parasite worm is spread by the bites of a black fly of the ''Simulium'' type. Usually, many bites are required before infection occurs. These flies live near rivers, hence the common name of the disease. Once inside a person, the worms create larvae that make their way out to the skin, where they can infect the next black fly that bites the person. There are a number of ways to make the diagnosis, including: placing a biopsy of the skin in normal saline and watching for the larva to come out; looking in the eye for larvae; and looking within the bumps under the skin for adult worms. A vaccine against the disease does not exist. Prevention is by avoiding being bitten by flies. This may include the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Code Of Zoological Nomenclature
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * Which name must be used in case of name conflicts * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus ''Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all animals, except where taxonomic judgment dictates otherwise. The code is meant to guid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onchocerca Volvulus
''Onchocerca volvulus'' is a filarial (arthropod-borne) nematode (roundworm) that causes onchocerciasis (river blindness), and is the second-leading cause of blindness due to infection worldwide after trachoma. It is one of the 20 neglected tropical diseases listed by the World Health Organization, with elimination from certain countries expected by 2020. John O’Neill, an Irish surgeon, first described ''Onchocerca volvulus'' in 1874, when he found it to be the causative agent of ‘craw-craw’, a skin disease found in West Africa. A Guatemalan doctor, Rodolfo Robles, first linked it to visual impairment in 1917. ''O. volvulus'' is primarily found in sub-Saharan Africa, and humans are the only known definitive host; there is also disease transmission in some South American nations, as well as Yemen (see global map bottom right). It is spread from person to person via female biting blackflies of the genus ''Simulium''. Morphology ''O. volvulus'' parasites obtain nutrients f ...

Gasteruptiidae
The Gasteruptiidae are one of the more distinctive families among the apocritan wasps, with surprisingly little variation in appearance for a group that contains around 500 species in two subfamilies ( Gasteruptiinae and Hyptiogastrinae) and with 6 genera worldwide. They are members of Evanioidea. Genera This family includes the following genera in two subfamilies: * Gasteruptiinae Ashmead, 1900 ** '' Gasteruption'' Latreille, 1777 ** '' Plutofoenus'' Kieffer, 1911 ** '' Spinolafoenus'' Macedo, 2009 ** '' Trilobitofoenus'' Macedo, 2009 * Hyptiogastrinae ** '' Hyptiogaster'' Kieffer, 1903 ** '' Pseudofoenus'' Kieffer, 1902 Several fossil species are also known: *Hypselogastriinae **'' Hypselogastrion'' Engel & Wang, 2016 Burmese amber, Myanmar, mid Cretaceous (latest Albian - earliest Cenomanian) *Kotujellitinae **†'' Kotujellites'' Rasnitsyn 1990 Taimyr amber, Russia Late Cretaceous (Cenomanian) **†'' Kotujisca'' Rasnitsyn 1991 Andaikhudag Formation, Mongolia, Early C ...

Commonwealth Institute Of Entomology
CABI (legally CAB International, formerly Commonwealth Agricultural Bureaux) is a nonprofit intergovernmental development and information organisation focusing primarily on agricultural and environmental issues in the developing world, and the creation, curation, and dissemination of scientific knowledge. Overview CABI is an international not-for-profit organisation. Their work is delivered through teams of CABI scientists and key partners working in over 40 countries across the world. CABI states its mission as "improving people’s lives worldwide by solving problems in agriculture and the environment". These problems include loss of crops caused by pests and diseases, invasive weeds and pests that damage farm production and biodiversity, and lack of global access to scientific research. Funding CABI states that only 3% of its revenue comes from core funding. Donors listed in the company's 2014 financial report include the UK's Department for International Development (£4, ...

Aulacidae
The Aulacidae are a small, cosmopolitan family of wasps, with two extant genera containing some 200 known species. They are primarily endoparasitoids of wood wasps (Xiphydriidae) and xylophagous beetles (Cerambycidae and Buprestidae). They are closely related to the family Gasteruptiidae, sharing the feature of having the first and second metasomal tergites fused, and having the head on a long pronotal "neck", though they are not nearly as slender and elongate as gasteruptiids, nor are their hind legs club-like, and they have more sculptured thoraces. They share the evanioid trait of having the metasoma attached very high above the hind coxae on the propodeum. While generally rarely collected, they can be locally abundant in areas undergoing logging or forest fires. The rich fossil record of Aulacidae indicates they were quite abundant in the Mesozoic The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is ...
