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] |
Xeris
''Xeris'' is a genus of horntails found in North America and Eurasia. Achille Costa circumscribed the genus in 1894. Synonyms In 1987, Malkiat S. Saini and Devinder Singh circumscribed a new genus, ''Neoxeris'' upon their description of a new species, which they called ''Neoxeris melanocephala''. In 2012, ''N. melanocephala'' was transferred to ''Xeris'', making ''Neoxeris'' a junior synonym. ''X. melanocephalus'' was later synonymized with ''X. himalayensis''. Description Characteristic features of ''Xeris'' compared to other genera of Siricidae genera include: a hind wing with which lacks a cell cup, a small vertical ridge behind the eye, and a metatibial spur. Distribution ''Xeris'' species are found in North America and Eurasia. In North America, they're found from the boreal forests in Alaska and Canada south through Chiapas in southern Mexico. They are found in temperate and boreal regions of Eurasia as well as mountains of southern Eurasia including Morocco, India, China ...

Urocerus
''Urocerus'' is a genus of horntails in the family Siricidae. There are about eight described species in ''Urocerus''. Species These species belong to the genus ''Urocerus'': * '' Urocerus albicornis'' ( Fabricius, 1781) (white horned horntail) * '' Urocerus californicus'' Norton, 1869 * '' Urocerus cressoni'' Norton, 1864 (black and red horntail) * '' Urocerus flavicornis'' Fabricius, 1781 (yellow-horned horntail wasp) * '' Urocerus franzinii'' C.Pesarini & F.Pesarini, 1977 * ''Urocerus gigas'' (Linnaeus, 1758) (giant woodwasp) * '' Urocerus japonicus'' (Smith, 1874) (Japanese horntail) * '' Urocerus sah'' ( Mocsáry, 1881) g Data sources: i = ITIS, c = Catalogue of Life, g = GBIF, b = Bugguide.net References Further reading * * * External links * Siricidae {{hymenoptera-stub ...

Sirex
''Sirex'' is a genus of wasps in the family Siricidae, the horntails or wood wasps. They inject eggs with fungal endosymbionts into wood. The fungus is contained in a mycangium which nourishes it with secretions, and in turn it digests wood for the wasp larva. The genus includes economically important pests; ''S. noctilio'', known simply as the 'Sirex woodwasp' is an invasive species, having spread widely across the world from its original range.Sirex Woodwasp – ''Sirex noctilio''.

Voltinism
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ibaliidae
The Ibaliidae are a small family of hymenopteran superfamily Cynipoidea. Ibaliidae differ from most of the cynipoids by the larvae being parasitoids on other wasp larvae in the group Siricidae. The Ibaliidae comprise three extant genera of fairly large wasps, with a total of 20 species, and is a sister group to the rest of the cynipoids except the small subfamily Austrocynipidae. Description Their large size is a typical and obvious characteristic in the family, with lengths up to . The following distinct features are diagnostic characters, based on research by Ronquist and Liu and Nordlander. Body The genae are swollen and pronounced. The female antenna consists of 11 segments, while the male antenna consists of 13 segments. A large portion of the pronotum is well developed, called the dorsal pronotal area, with scutellar processes. The marginal cell of the forewing is elongated and thin. The gaster is long and pronouncedly compressed laterally. The seventh tergum is large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsuga
''Tsuga'' (, from Japanese (), the name of ''Tsuga sieboldii'') is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The common name hemlock is derived from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant poison hemlock. Unlike the latter, ''Tsuga'' species are not poisonous. The genus comprises eight to ten species (depending on the authority), with four species occurring in North America and four to six in eastern Asia. Description They are medium-sized to large evergreen trees, ranging from tall, with a conical to irregular crown, the latter occurring especially in some of the Asian species. The leading shoots generally droop. The bark is scaly and commonly deeply furrowed, with the colour ranging from grey to brown. The branches stem horizontally from the trunk and are usually arranged in flattened sprays that bend downward towards their tips. Short spur shoots, which are present in many gymnosperms ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...
