Cardiochilinae
The Cardiochilinae are a subfamily of braconid parasitoid wasps. This subfamily has been treated as a tribe of Microgastrinae in the past. Some species including ''Toxoneuron nigriceps'' have been used in biocontrol programs. Description and distribution Cardiochilines are non-cyclostome braconids with a similar appearance to Microgastrines. They possess the r-m vein of the forewing and have more than 16 flagellomeres. Cardiochilines can be found worldwide. Biology Cardiochilinae are solitary koinobiont endoparasitoids of caterpillars. Female Cardiochilinae inject a polydnavirus into the host during 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 typical ....

Polydnavirus
A polydnavirus (PDV) is a member of the family (biology), family ''Polydnaviridae'' of insect viruses. There are two genera in the family: ''Bracovirus'' and ''Ichnovirus''. Polydnaviruses form a symbiotic relationship with parasitoid wasps; (ichnoviruses (IV) occur in Ichneumonidae, ichneumonid wasps and bracoviruses (BV) in Braconidae, braconid wasps). The larvae of wasps in both of those groups are themselves parasitic on Lepidoptera (moths and butterflies), and the polydnaviruses are important in circumventing the immune response of their parasitized hosts. Little or no sequence homology exists between BV and IV, suggesting that the two genera have been evolving independently for a long time. Taxonomy The genus contains the following genera: * ''Bracovirus'' * ''Ichnovirus'' Structure Viruses in ''Polydnaviridae'' are viral envelope, enveloped, with prolate ellipsoid and cylindrical geometries. Genomes are circular and segmented, composed of multiple segments of double-str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braconid
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include ''Aerophilus'', ''Aleiodes'', ''Apanteles'', ''Asobara'', '' Bracon'', ''Cenocoelius'', '' Chaenusa'', ''Chorebus'', ''Cotesia'', '' Dacnusa'', '' Diachasma'', ''Microgaster'', ''Opius'', ''Parapanteles'', '' Phaenocarpa'', ''Spathius'', and ''Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the labrum and the lower part of the clypeus are concave with respect to the upper clypeus and the dorsal margin of the mandibles. These ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Parasitic 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 viru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microgastrinae
Microgastrinae is a subfamily of braconid wasps, encompassing almost 3,000 described species, with an estimated 30,000–50,000 total species. This makes it one of the richest subfamilies with the most species of parasitoid wasps. Genera These 84 genera belong to the subfamily Microgastrinae: * '' Agupta'' Fernandez-Triana, 2018 * '' Alloplitis'' Nixon, 1965 * '' Alphomelon'' Mason, 1981 * '' Apanteles'' Förster, 1862 * '' Austinicotesia'' Fernandez-Triana, 2018 * '' Austrocotesia'' Austin & Dangerfield, 1992 * ''Beyarslania'' Koçak & Kemal, 2009 * '' Billmasonius'' Fernandez-Triana, 2018 * '' Buluka'' de Saeger, 1948 * '' Carlmuesebeckius'' Fernandez-Triana, 2018 * '' Chaoa'' Luo & You, 2004 * '' Choeras'' Mason, 1981 * ''Clarkinella'' Mason, 1981 * '' Cotesia'' Cameron, 1891 * '' Cuneogaster'' Choi & Whitfield, 2006 * '' Dasylagon'' Muesebeck, 1958 * '' Deuterixys'' Mason, 1981 * ''Diolcogaster'' Ashmead, 1900 * '' Distatrix'' Mason, 1981 * '' Dodogaster'' Rousse, 2013 * '' D ...

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] |
Caterpillars
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpilla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovipositor
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 ...
