	Julius Theodor Christian Ratzeburg Julius Theodor Christian Ratzeburg (16 February 1801– 24 October 1871) was a German zoologist, botanist, entomologist, and forester. Biography Ratzeburg was born in Berlin, the son of a professor at the veterinary school of the University of Berlin. He studied medicine and natural sciences in Berlin and was primarily interested in botany. He became a private lecturer at the University of Berlin in 1828, when he was in contact with Alexander and Wilhelm von Humboldt. Two years later, he became professor of natural history there at the invitation of Friedrich Wilhelm Leopold Pfeil (1783-1859). He founded the botanic garden of forestry at Eberswalde, working there until his retirement in 1869. He returned to Berlin, where he resided until his death. Ratzeburg was the author of important works on forestry and forest entomology, and is considered the founder of the latter discipline. He was notably interested in parasitic species. From 1827 to 1834, he wrote ''Medizinische Zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Megaspilidae The Megaspilidae are a small hymenopteran family with 13 genera in two subfamilies, and some 450 known species, with a great many species still undescribed. It is a poorly known group as a whole, though most are believed to be parasitoids (especially of sternorrhynchan Hemiptera), and a few hyperparasitoids. Many are found in the soil, and of these, a number are wingless. The family is distinguished from the closely related Ceraphronidae by having a very large stigma in the wing, a relatively constricted metasomal petiole, and three grooves in the mesoscutum. The largest genus within Megaspilidae is '' Dendrocerus''. The second largest genus is ''Conostigmus''.

picture info	Parasitic Wasps Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders. Parasitoid wasp species differ in which host life-stage they attack: eggs, larvae, pupae, or adults. They mainly follow one of two major strategies within parasitism: either they are endoparasitic, developing inside the host, and koinobiont, allowing the host to continue to feed, develop, and moult; or they are ectoparasitic, developing outside the host, and idiobiont, paralysing the host immediately. Some endoparasitic wasps of the superfamily Ichneumonoidea have a mutualistic relationship with polydnaviruses, the viru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Ceraphronoidea The Ceraphronoidea are a small hymenopteran superfamily that includes only two families, and a total of some 800 species, though a great many species are still undescribed. It is a poorly known group as a whole, and most are believed to be parasitoid or hyperparasitoids. The two families are unified by several characters, the most visible of which is their wing venation is greatly reduced in a very specific and unique way; the costal and radial veins have fused so no costal cell is present, a short break occurs at the stigma, and the only vein in the wing membrane itself is the radial sector, which is short and curved, arising from the stigma. The taxon was erected by Alexander Henry Haliday. Some fossil families that were formerly assigned to this group have since been reassigned elsewhere including Aptenoperissidae, Radiophronidae and Stigmaphronidae.

picture info	Hymenoptera Genera Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Taxa Named By Julius Theodor Christian Ratzeburg In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
