Coccoidea
Scale insects are small insects of the Order (biology), order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as Honeydew (secretion), honeydew on which sooty mold tends to grow. The insects often have a Mutualism (biology), mutualistic relationship with ants, which feed on the honeydew and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gordon Floyd Ferris
Gordon Floyd Ferris (January 2, 1893, in Bayard, Kansas – May 21, 1958) was an American entomologist who served as professor of biology at Stanford University from 1912 to 1958 and earned a reputation for his teaching. He founded and edited the journal ''Microentomology,'' preferring to work on insects that could only be examined on microscopic slides''.'' He was a specialist on the systematics of the Coccoidea. Ferris was born in Bayard, Kansas, where his father was a railroad worker. When he was young the family moved to Monticello, Missouri, where they lived in a log cabin. His mother died when he was three and he went to live with his paternal grandparents in La Harpe, Kansas. Leslie, an older brother went to Ottawa and helped Ferris join Ottawa University in 1909. Ferris however was unable to complete studies and planned to join the navy. Leslie found Ferris a job the Telluride power company. The power company was interested in training its people, mostly at Cornell Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

NRC Research Press
Canadian Science Publishing (CSP) is Canada's largest publisher of international scientific journals. It started in 1929 as the ''NRC Research Press'', part of the National Research Council (NRC). In 2010, the organization spun off from NRC and was incorporated as a not-for-profit. As of 2018, CSP has published about 2,300 articles annually in 24 journals distributed to over 125 countries. CSP has 50 staff members, and, according to the website Owler, its annual revenue is about US$3.7M. All of CSP's journals are produced and delivered in both HTML and PDF formats, is connected to scientific literature, included in all major indexes, and archived through both CLOCKSS and Portico. Open access CSP has an ''OpenArticle'' program, which permits authors and/or research funding agencies to sponsor online open access of their article. It also has auto-deposit of accepted manuscripts into the University of Toronto ''TSpace'', a free and secure research repository; and an adoption ...

Hemiptera Families
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles.
