Herbert Osborn
Herbert Osborn (March 19, 1856-September 20, 1954) was an American entomologist. Biography He was born in Lafayette, Walworth County, Wisconsin. He held various posts at Iowa State College, eventually becoming head of the Department of Zoology and Entomology from 1882 to 1897, and was the first State Entomologist of Iowa in 1898. He left Iowa in 1898 to become chairman of the Department of Zoology and Entomology at Ohio State University (1898-1916), where he was later named emeritus professor. He died in Columbus, Ohio. Much of Professor Osborn's research was concerned with the Hemiptera, especially the leafhoppers of the Cicadellidae. He also studied economically important insects of the Anoplura and Thysanoptera. More than 500 publications bear his name.

Thysanoptera
Thrips (order Thysanoptera) are minute (mostly long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Entomologists have described approximately 7,700 species. They fly only weakly and their feathery wings are unsuitable for conventional flight; instead, thrips exploit an unusual mechanism, clap and fling, to create lift using an unsteady circulation pattern with transient vortices near the wings. Thrips are a functionally diverse group; many of the known species are fungivorous. A small proportion of the species are serious pests of commercially important crops. Some of these serve as vectors for over 20 viruses that cause plant disease, especially the Tospoviruses. Many flower-dwelling species bring benefits as pollinators, with some predatory thrips feeding on small insects or mites. In the right conditions, such as in greenhouses, invasive species can exponentially increase in population size and form large swarms because of a lack of na ...

Leafhopper
Leafhopper is the common name for any species from the family (biology), family Cicadellidae: based on the type genus ''Cicadella''. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or Vector (epidemiology), vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hessian Fly
The Hessian fly (''Mayetiola destructor''), or barley midge, is a species of fly that is a significant pest of cereal crops, including wheat, barley and rye. Though a native of Asia, upon its discovery it was believed to have been transported into North America in the straw bedding of Hessian troops during the American Revolution (1775–1783), thus the origin of its common name. However, the report of an inquiry made in 1788 by Sir Joseph Banks states that "no such insect could be found to exist in Germany or any other part of Europe". Nonetheless, it appears that this species, or one exactly like it in habits, had been known for at least a century prior to the American Revolution from a locality near Geneva, and also for a long time from some regions in France. The Hessian fly was described by Thomas Say in 1817. It is a very harmful insect. It mainly attacks the stem, although if it is especially hungry it will eat any part of the plant it can find. In 1836, a severe infes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blissus Leucopterus
''Blissus leucopterus'', also known as the true chinch bug, is a small North American insect in the order Hemiptera and family Blissidae. It is the most commonly encountered species of the genus '' Blissus'', which are all known as chinch bugs. A closely related species is ''B. insularis'', the southern chinch bug. The name of the chinch bug is derived from the Spanish ', which refers to the bed bug and is in turn derived from the Latin ''cimex''. The chinch bug is not related to the bed bug, but took this name on account of producing a similar smell to that of bed bugs when crushed. These bugs tend to gather on sunny, open patches of turfgrass. Due to their small size, chinch bugs are hardly noticeable, so they become problems, since they are considered pests that feed on stems of turfgrass and grain crops. Identification ''B. leucopterus'' is about long when fully developed. The adults' bodies vary in colour from dark red to brown with white wings and red legs. Young nymph ...

Anoplura
Sucking lice (known scientifically as Anoplura) are a parvorder of around 550 species of lice. All sucking lice are blood-feeding ectoparasites of mammals. They can cause localized skin irritations and are vectors of several blood-borne diseases. At least three species or subspecies of Anoplura are parasites of humans; the human condition of being infested with sucking lice is called pediculosis. ''Pediculus humanus'' is divided into two subspecies, ''Pediculus humanus humanus'', or the human body louse, sometimes nicknamed "the seam squirrel" for its habit of laying of eggs in the seams of clothing, and ''Pediculus humanus capitis'', or the human head louse. ''Pthirus pubis'' (the human pubic louse) is the cause of the condition known as crabs. Classification Sucking lice are classified as a parvorder called Anoplura, named by Leach in 1815. Anoplura belongs to the infraorder Phthiraptera, which contains all lice, and is part of the larger order Psocodea, which also con ...

Iowa State College
Iowa State University of Science and Technology (Iowa State University, Iowa State, or ISU) is a public land-grant research university in Ames, Iowa, United States. Founded in 1858 as the Iowa Agricultural College and Model Farm, Iowa State became one of the nation's first designated land-grant institutions when the Iowa Legislature accepted the provisions of the 1862 Morrill Act on September 11, 1862.

Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising more than 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 sometimes 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 varieties 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. ...
