Diplolepis (wasp)
''Diplolepis'' is a genus of approximately fifty species of gall-inducing wasps in the family Diplolepididae. The larvae induce galls on wild roses (''Rosa''), and rarely on domestic roses. Description Adults are small () with a strongly arched mesosoma giving them a hunched appearance. Coloration ranges from entirely orange to reddish-brown or black. Larvae are legless and cream-colored with a weakly defined head. Galls formed by a given species can usually be distinguished from those of other species by the shape, size, placement, and ornamentation (smooth or spiny) of the gall, together with the identity of the host plant. However, gall morphology can be modified by the presence of inquilines and parasitoids. Some species induce galls on leaves, while others induce galls on stems or adventitious shoots. Depending on the species of wasp, galls may be single-chambered or multi-chambered, and detachable or integral. Range ''Diplolepis'' species occur throughout the holarct ...

Diplolepis Rosae
''Diplolepis rosae'' is a gall wasp which causes a gall known as the rose bedeguar gall, Robin's pincushion, mossy rose gall, or simply moss gall.Darlington, Arnold (1975) ''The Pocket Encyclopaedia of Plant Galls in Colour.'' Pub. Blandford Press. Poole. . P. 133 - 135. The gall develops as a chemically induced distortion of an unopened leaf axillary or terminal bud, mostly on field rose ('' Rosa arvensis'') or dog rose (''Rosa canina'') shrubs. The female wasp lays up to 60 eggs within each leaf bud using her ovipositor. The grubs develop within the gall, and the wasps emerge in spring; the wasp is parthenogenetic with fewer than one percent being males. A similar gall is caused by '' Diplolepis mayri'', but this is much less common. Names Being so prominent and interesting in appearance, this gall has more folklore attached to it than most. The term 'Bedeguar, Bedegar or Bedequar' comes from a French word, ''bédégar'', and is ultimately from the Persian, ''bād-āwar'', mea ...

Oviposition
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Ichneumonidae
The Ichneumonidae, also known as the ichneumon wasps, Darwin wasps, or ichneumonids, are a family (biology), family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species currently described. However, this likely represents less than a quarter of their true Species richness, richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, Species distribution, distribution, and evolution.Quicke, D. L. J. (2015). The braconid and ichneumonid parasitoid wasps: biology, systematics, evolution and ecology. Chichester: John Wiley & Sons, Ltd. Ichneumonid wasps, with very few exceptions, attack the immature stages of Holometabolism, holometabolous insects and spiders, eventually killing their hosts. They thus fulfill an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for Biological p ...

Torymidae
Torymidae is a family of wasps in the superfamily Chalcidoidea. Most species in this family are small with attractive metallic coloration, and females generally have long ovipositors. Many are parasitoids on gall-forming insects, and some are phytophagous (plant-eating) species, sometimes using the galls formed by other insects. Over 960 species in about 70 genera are found worldwide. They are best recognized in that they are one of the few groups of Chalcidoidea Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, me ... in which the cerci are visible. Systematics The family was first described by Walker in 1833 and the infrafamiliar classification has been revised several times. A number of subfamilies were created within Torymidae, some of which have since been transferred to other fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteromalidae
The Pteromalidae are a very large family of mostly parasitoid wasps, with some 3,450 described species in about 640 genera (the number was greater, but many species and genera have been reduced by synonymy in recent years). The subfamily-level divisions of the family are highly contentious and unstable, and the family is thought to be "artificial", composed of numerous, distantly related groups (polyphyletic). Accordingly, details of their life histories range over nearly the entire range possible within the Chalcidoidea, though the majority are (as with most chalcidoids) parasitoids of other insects. They are found throughout the world in virtually all habitats, and many are important as biological control agents. The oldest known fossil is known from the Early Cretaceous. In essence, a "pteromalid" is any member of the Chalcidoidea that has five-segmented tarsi and does not have the defining features of any of the remaining families with five-segmented tarsi. It is highly prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ormyridae
The Ormyridae are a small family of parasitic wasps in the superfamily Chalcidoidea. They are either parasitoids or hyperparasitoids on gall-forming insects, primarily cynipid wasps and tephritid flies. The 120 or so species in three genera (mostly in the genus ''Ormyrus'') are cosmopolitan, except almost entirely absent from South America. They are best recognized by distinctive scalloped sculpturing of their metasomal tergite A ''tergum'' (Latin for "the back"; plural ''terga'', associated adjective tergal) is the dorsal ('upper') portion of an arthropod segment other than the head. The anterior edge is called the 'base' and posterior edge is called the 'apex' or 'mar ...s.

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. 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'' * '' Aximopsis'' * '' Banyoma'' * '' Bephrata'' * '' Bephratelloides'' * '' Bephratoides'' * '' Bruchodape'' * ''Bruchophagus'' * '' Burksoma'' * '' Camponotophilus'' * '' Cathilaria'' * '' Chryseida'' * '' Chryseurytoma'' * '' Endobia'' * '' Eudoxin ...

Eupelmidae
Eupelmidae is a family of parasitic wasps in the superfamily Chalcidoidea. The group is apparently polyphyletic, though the different subfamilies may each be monophyletic, and may be elevated to family status in the near future. As presently defined, there are over 905 described species in 45 genera. The larvae of the majority are primary parasitoids, commonly on beetle larvae, though many other hosts are attacked, including spiders, and details of the life history can be variable (e.g., some attack eggs and others are hyperparasites). They are found throughout the world in virtually all habitats. They are somewhat variable in appearance, though a fair number of species are relatively easy to separate from other Chalcidoidea by the possession of a medially concave mesonotum. They also have the unusual tendency to arch the body strongly upwards when dead, with the head and metasoma often nearly touching above the thorax.

Eulophidae
The Eulophidae are a large family of hymenopteran insects, with over 4,300 described species in some 300 genera. The family includes the genus ''Elasmus'', which used to be treated as a separate family, "Elasmidae", and is now treated as a subfamily of Eulophidae. These minute insects are challenging to study, as they deteriorate rapidly after death unless extreme care is taken (e.g., preservation in ethanol), making identification of most museum specimens difficult. The larvae of a very few species feed on plants, but the majority are primary parasitoids on a huge range of arthropods at all stages of development. They are exceptional in that they are one of two hymenopteran families with some species that are known to parasitize thrips. Eulophids are found throughout the world in virtually all habitats (one is even aquatic, parasitising water-penny beetles). Eulophids are separable from most other Chalcidoidea by the possession of only four tarsomeres on each leg, a small, st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitoid Wasp
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 vir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
