Entomology
Entomology () is the 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, 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. They have many kinds of int ...

Phloem
Phloem (, ) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as ''photosynthates'', in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Ancient Greek word (''phloiós''), meaning "bark". The term was introduced by Carl Nägeli in 1858. Structure Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids. Conducting cells (sieve elements) Sieve elements are the type of cell that are responsible for transporting sugars throughout the plant. At maturity they lack a nucleus and have very few organelles, so they rely on companion cells or albuminous cells for most of their metabolic ...

Ecological Entomology
The Royal Entomological Society is devoted to the study of insects. Its aims are to disseminate information about insects and improving communication between entomologists. The society was founded in 1833 as the Entomological Society of London. It had many antecedents beginning as the Society of Entomologists of London. History The foundation of the society began with a meeting of "gentlemen and friends of entomological science", held on 3 May 1833 in the British Museum convened by Nicholas Aylward Vigors with the presidency of John George Children. Those present were the Reverend Frederick William Hope, Cardale Babington, William Yarrell, John Edward Gray, James Francis Stephens, Thomas Horsfield, George Thomas Rudd and George Robert Gray. Letters of Adrian Hardy Haworth, George Bennett and John Curtis were read where they expressed their regrets to be unable to attend the meeting. They decided that a society should be created for the promotion of the science o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Annual Review Of Entomology
The ''Annual Review of Entomology'' is a peer-reviewed academic journal that publishes review articles about entomology, the study of insects. First published in 1956 from a collaboration between the Entomological Society of America and Annual Reviews, its longest-serving editors are Thomas E. Mittler (1967–1997) and May Berenbaum (1998–2018). As of 2022, it has a 2021 impact factor of 22.682. History In 1953, a committee within the Entomological Society of America examined the volume of literature published each year in the field and recommended that a journal be established that published review articles. The Entomological Society approached the nonprofit publisher Annual Reviews, which also agreed that there was a need for a review series in entomology. The ''Annual Review of Entomology'' published its first volume in 1956, making it the tenth title published by Annual Reviews. At first, the ESA remained involved with the operation of the journal and confirmed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reginald Frederick Chapman
Reginald Frederick Chapman (2 July 1930 – 2 May 2003) was an English entomologist who later worked at the University of Arizona. He wrote a landmark textbook on the anatomy and physiology of insects, ''The Insects- Structure and Function'', several editions of which have been published. Chapman was born in London and received a bachelor's degree in science from Queen Mary College, London in 1951. After a Ph.D. at Birkbeck College, he joined in 1953, the locust control service in East Africa and from 1957 he worked at the University of Ghana, studying tsetse flies. In 1959 he returned to Birkbeck to teach zoology. In 1969 he published ''The Insects- Structure and Function'' which was to go into numerous editions.

Entomological Society Of America
The Entomological Society of America (ESA) was founded in 1889 and today has more than 7,000 members, including educators, extension personnel, consultants, students, researchers, and scientists from agricultural departments, health agencies, private industries, colleges and universities, and state and federal governments.

Drosophila
''Drosophila'' () is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of ''Drosophila'' in particular, '' D. melanogaster'', has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "''Drosophila''" are often used synonymously with ''D. melanogaster'' in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
