Stephanidae
The Stephanidae, sometimes called crown wasps, are a family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contain four extinct genera described from both compression fossils and inclusions in amber. Biology Stephanids are noted for their ocellar corona, a semicircular to circular set of projections around the middle ocellus, forming a "crown" on the head. Only stephanids and the similarly old Hymenoptera family Orussidae have ocellar coronae, and it is uncertain if they developed the structure separately or if a common ancestor of both developed it and it was then lost in all but the two families. Weakly developed grooves starting at the base of the antennae and extending past the eyes to the back of the head capsule are present. ...

Megischus
''Megischus'' is a genus of crown wasp. It was circumscription (taxonomy), circumscribed by Gaspard Auguste Brullé in 1846. The genus has a cosmopolitan distribution, and over eighty species are recognized. It is the type genus of the tribe (biology), tribe Megischini, which was circumscribed by Michael S. Engel and David A. Grimaldi in 2004. This tribe is in the subfamily Stephaninae in the family Stephanidae; the other genera in this tribe are ''Hemistephanus'' and ''Pseudomegischus''. Species include: *''Megischus alveolifer'' *''Megischus anaxeus'' *''Megischus annulator'' References {{Taxonbar, from=Q18595266 Stephanoidea Hymenoptera genera ...

Stephanus Serrator
''Stephanus serrator'' is a species of parasitic wasp in the family Stephanidae, the crown wasps. This species is native to much of Europe and is to be seen in the breeding season on recently dead timber or wood products. The larvae are parasitoids of the larvae of wood-boring beetles. Description Stephanid wasps are known as crown wasps because the top of the wasp's head bears a group of five tubercles. The somewhat elongated prothorax is connected to the propodeum (the first abdominal segment) by a very long petiole, and the ventral side of the hind femur bears teeth. The male ''S. serrator'' averages in length and the female , with an ovipositor of . The slender body and legs are black, apart from the front half of the abdomen and certain leg segments, which are red. Distribution ''S. serrator'' is known from Spain, France, Netherlands, Italy, Germany, Switzerland, Austria, Czech Republic, Hungary, Romania, Bulgaria, Croatia, Serbia and Montenegro. Adults can be found on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orussidae
The Orussidae or the parasitic wood wasps represent a small family of sawflies (" Symphyta"). Currently, about 93 extant and four fossil species are known. They take a key position in phylogenetic analyses of Hymenoptera, because they form the sister taxon of the megadiverse apocritan wasps, and the common ancestor of Orussidae + Apocrita evolved parasitism for the first time in course of the evolution of the Hymenoptera. They are also the only sawflies with carnivorous larvae. Description Adults The fully winged wasps are 2−23 mm long. They are predominantly black but species of ''Chalinus'', ''Mocsarya'' and ''Orussobaius'' are more or less metallic. Some species have a red thorax or abdomen and conspicuous white or golden pilosity. Many ''Orussus'' species bear white spots on the legs. The antennae of males are composed of 11, those of females of 10 articles. The modified distal antennal articles of females (article 9 enlarged, article 10 very small) are involved in ...

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] |

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
