Andricus Quercusstrobilanus
''Andricus quercusstrobilanus'', the lobed oak gall wasp, is a species of gall wasp in the family Cynipidae, found in North America. The ''quercus'' in its specific name is the genus name for oak, while "strobilus" is derived from the Greek ''strobilo'' which means "cone", a reference to the cone shape of the gall; thus the gall is sometimes called pine cone oak gall. Description Larvae induce a cluster of wedge-shaped galls on white oaks, including bur oak, swamp white oak, and overcup oak. The galls are irregular, cone-shaped bodies that are closely packed together, with their pointed bases attached to a common centre. These wedges are hard and corky and break off very easily when the gall is dry. Each of them contains a hollow kernel with a plump, large larva inside. The galls undergo color change from pink or red to yellow and finally to brown. Adults of the species have not been described. Ecology Guest wasps found in the galls include inquilines such as '' Syner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Robert Osten-Sacken
Carl Robert Osten-Sacken or Carl-Robert Romanovich, Baron von der Osten-Sacken, Baron Osten Sacken (21 August 1828, – 20 May 1906) was a German-Russian diplomat and entomologist. He served as the Russian consul general in New York City during the American Civil War, living in the United States from 1856 to 1877. He worked on the taxonomy of flies in general and particularly of the family Tipulidae (crane flies). Early life Carl Robert Osten-Sacken was born on 21 August 1828 in St. Petersburg as the son of Baltic Germans, Baltic German Baron Reinhold Friedrich von der Osten-Sacken (1791-1864) and his wife, Elisabeth von Engelhardt family, Engelhardt (1805-1873). Biography He took an interest in insects at the age of eleven through the influence of Joseph N. Schatiloff, a Russian coleopterist. In 1849 he joined the Imperial Foreign Office and while still in Russia he published his first entomological papers, including an account of the species found in the suburbs of St. ...

Quercus Macrocarpa
''Quercus macrocarpa'', the bur oak or burr oak, is a species of oak tree native to eastern North America. It is in the white oak section, ''Quercus'' sect. ''Quercus'', and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak (thus the species name ''macrocarpa'', from Ancient Greek "large" and "fruit"), and are important food for wildlife. Description ''Quercus macrocarpa'' is a large deciduous tree growing up to , rarely , in height, and is one of the most massive oaks with a trunk diameter of up to . It is one of the slowest-growing oaks, with a growth rate of per year when young. However, one source states that a well-established tree can grow up to per year. A 20-year-old tree will be about tall if grown in full sun. Naturally occurring saplings in forests will typically be older. Bur oaks commonly live to be 200 to 300 years old, and may live up to 400 years. The bark is gray with distinct ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Carl Robert Osten-Sacken
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurytomidae
The Eurytomidae are a family within the superfamily Chalcidoidea. Unlike most chalcidoids, the larvae of many are phytophagous (feeding in stems, seeds, or galls), while others are more typical parasitoids, though even then the hosts are usually found within plant tissues. Some species of eurytomids are unusual in the sense that they are parasitoids of spider eggs. Females of this group are idiobionts that probe through the thin silk of spider egg sacs and oviposit into individual spider eggs that are clustered within the sacs. They are found throughout the world in virtually all habitats, and a few are considered pests. They tend to be dull and not metallic, and heavily punctured, with very thick, collar-like pronota. Taxa , Eurytomid genera include: Buresiinae Lotfalizadeh et al., 2007 * '' Buresium'' * '' Macrorileya'' Eurytominae * '' Aiolomorphus'' * '' Aranedra'' * '' Austrodecatoma'' * '' Ausystole'' * '' Axanthosoma'' * '' Axanthosomella'' * ''Axima'' ...

Parasitoids
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synergus Lignicola
''Synergus'' is a genus of gall wasp in the tribe Synergini. It is found worldwide. Species in ''Synergus'' are generally inquilines, which means they use the galls of other species of gall wasps. ''Synergus'' uses the galls of Cynipini on oak trees. Species As of 2024, there are at least 127 species in ''Synergus''. Notable species include: * '' Synergus itoensis'' ** Only ''Synergus'' species known to induce its own gall. * '' Synergus japonicus'' * '' Synergus vulgaris'' Hartig, 1840 ** The type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ... for ''Synergus'' References {{Taxonbar, from=Q14497561 Gall-inducing insects Cynipidae Hymenoptera genera ...

Inquilines
In zoology, an inquiline (from Latin ''inquilinus'', "lodger" or "tenant") is an animal that lives commensally in the nest, burrow, or dwelling place of an animal of another species. For example, some organisms, such as insects, may live in the homes of gophers or the garages of humans and feed on debris, fungi, roots, etc. The most widely distributed types of inquiline are those found in association with the nests of social insects, especially ants and termites – a single colony may support dozens of different inquiline species. The distinctions between parasites, social parasites, and inquilines are subtle, and many species may fulfill the criteria for more than one of these, as inquilines do exhibit many of the same characteristics as parasites. However, parasites are specifically ''not'' inquilines, because by definition they have a deleterious effect on the host species, while inquilines have not been confirmed to do so. In the specific case of termites, the term " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Lyrata
''Quercus lyrata'', the overcup oak, is an oak in the white oak group (''Quercus'' sect. ''Quercus''). The common name, overcup oak, refers to its acorns that are mostly enclosed within the acorn cup. It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas, inland as far as Oklahoma, Missouri, and Illinois. There are historical reports of it growing in Iowa, but the species appears to have been extirpated there. It is a slow-growing tree that often takes 25 to 30 years to mature. It has an estimated lifespan of 400 years.Solomon, J. D. (1990). Quercus lyrata Walt. overcup oak. ''Silvics of North America'', ''2'', 681-685.

Quercus Bicolor
''Quercus bicolor'', the swamp white oak, is a North American species of medium-sized trees in the beech family. It is a common element of America's north central and northeastern mixed forests. It can survive in a variety of habitats. It forms hybrids with bur oak where they occur together in the wild. Description ''Quercus bicolor'' grows rapidly and can reach tall with the tallest known reaching and lives up to 285 years. The bark resembles that of the white oak. The leaves are broad ovoid, long and broad, always more or less glaucous on the underside, and are shallowly lobed with five to seven lobes on each side, intermediate between the chestnut oak and the white oak. In autumn, they turn brown, yellow-brown, or sometimes reddish, but generally, the color is not as reliable or as brilliant as the white oak can be. The fruit is a peduncled acorn, , rarely , long and broad, maturing about six months after pollination. Good crops of swamp white oak occur every 3 to 5 y ...

White Oaks
''Quercus'' subgenus ''Quercus'' is one of the two subgenera into which the genus ''Quercus'' was divided in a 2017 classification (the other being subgenus ''Cerris''). It contains about 190 species divided among five sections. It may be called the New World clade or the high-latitude clade; most species are native to the Americas, the others being found in Eurasia and northernmost North Africa. Description Members of subgenus ''Quercus'' are distinguished from members of subgenus ''Cerris'' by few morphological features, their separation being largely determined by molecular phylogenetic evidence. All are trees or shrubs bearing acorn-like fruit in which a cup covers at least the base of the nut. The outer structure of the mature pollen is one feature that distinguishes the two subgenera: in subgenus ''Quercus'', the small folds or wrinkles (rugulae) are obscured by sporopollenin, whereas in subgenus ''Cerris'', the rugulae are visible or at most weakly obscured.
