Meteorinae is a subfamily of braconid parasitoid wasps; however, since 2015, most scientists have treated this clade as the Tribe Meteorini in Euphorinae. [1] [2] Several species have been used in biological control programs. The name for this group comes from the pupal stage, which, in species attacking Lepidopteran hosts, hangs suspended from a long thread of silk. [3]
Meteorines are characterized by an open 1st subdiscal cell and a four-sided 2nd subdiscal cell of the forewings. They have a distinctive petiolate waist. [3]
They are found worldwide, in habitats where their hosts can be found. [3]
Meteorines are koinobiont endoparasitiods of Coleoptera or Lepidoptera larvae. Some species are known to have broad host ranges, meaning they can attack many species of hosts. Most are solitary, laying a single egg per host, but some are gregarious and many larvae develop within a single host. Many species are nocturnal as adults. [3]
Two genera are found in North America, Meteorus and Zele . Recent evidence suggests that Meteorus may be paraphyletic with respect to Zele, but synonymyzing the two genera could potentially cause great confusion in the scientific literature. [1]
Many hosts of Meteorines are considered pests, especially of forests, making them good candidates for biocontrol projects. Meteorus pulchricornus has been imported to North America on multiple occasions to attempt to control the gypsy moth. [4] M. vesicolor was introduced to the United States in the early 1900s for the control of the brown-tail moth. [5] M. trachynotus was investigated for control of spruce budworm [6] as was M. hypophloei for controlling bark beetles. [7] Other species have been used in control of cutworms, avocado looper, and swallowtail pests on citrus crops. [3]
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation.
The Tachinidae are a large and variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. Over 1,300 species have been described in North America alone. Insects in this family commonly are called tachinid flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods, usually other insects. The family is known from many habitats in all zoogeographical regions and is especially diverse in South America.
Sawflies are wasp-like insects that are in the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
The superfamily Ichneumonoidea contains one extinct and three extant families, including the two largest families within Hymenoptera: Ichneumonidae and Braconidae. The group is thought to contain as many as 100,000 species, many of which have not yet been described. Like other parasitoid wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, now known to be paraphyletic.
The Ichneumonidae, also known as ichneumon wasps, ichneumonid wasps, ichneumonids, or Darwin wasps, are a 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 described as of 2016. However, this likely represents less than a quarter of their true richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, distribution, and evolution. It is estimated that there are more species in this family than there are species of birds and mammals combined. Ichneumonid wasps, with very few exceptions, attack the immature stages of holometabolous insects and spiders, eventually killing their hosts. They play an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control.
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.
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.
Glyptapanteles is a genus of endoparasitoid wasps found in all continents, except Antarctica. The larvae of Glyptapanteles species are able to manipulate their hosts into serving as bodyguards.
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.
The Euphorinae are a large subfamily of Braconidae parasitoid wasps. Some species have been used for biological pest control. They are sister group to the Meteorinae.
Cotesia is a genus of braconid wasps first described by Peter Cameron in 1891. Some species parasitize caterpillars of species considered pests, and are used as biocontrol agents. Cotesia congregata parasitizes the tomato and the tobacco hornworms. C. glomerata and C. rubecula feed on the cabbage white and other white butterfly caterpillars. C. gonopterygis and C. risilis are host-specific and parasitize the common brimstone.
Cotesia urabae is a small wasp, having a black body with yellow-brown legs, characterized by a solitary larval endoparasitoid stage. It is part of a large complex of 11 primary parasitoids of Uraba lugens Walker, many of which are polyphagous. The female inserts its ovipositor into the a U. lugens larva, depositing its eggs there, and it has been found that one female may carry up to 400 eggs. While C. urabae females are able to attack the same larva several times; only one single parasitoid completes its development in each larva.
Meteorus is a genus of parasitoid wasps in the family Braconidae. It comprises over 330 species worldwide.
Bracon is a genus of wasps in the Braconidae, a family of parasitoid wasps. There are several hundred described species but there are thousands still undescribed. The genus is cosmopolitan, distributed throughout the world, with most of the described species occurring in the Palearctic realm.
Spathius is a genus of doryctine wasps. The larvae of this genus of wasps feed on beetle larvae. They act as biological controllers of the certain pest beetles, such as Hylurgopinus rufipes and the emerald ash borer.
The Rogadinae are a large subfamily of braconid parasitoid wasps. Several Rogadinae species parasitize pest caterpillars and are important for naturally occurring biological control.
Adeliini is a tribe of braconid wasps within the subfamily Cheloninae. Until 2016, Adeliini was classified as a separate subfamily, the Adeliinae. They are small, stout-bodied braconids that parasitize the larvae of leaf-mining moths. Despite being widespread, they tend to be rare in entomological collections.
The Cenocoeliinae are a subfamily of braconid parasitoid wasps.
Lysiphlebus testaceipes is a species of small braconid parasitoid wasp in the subfamily Aphidiinae. L. testaceipes can utilize numerous species of aphids as hosts and has often been used as a biological control agent against aphid pests. It is considered an invasive species in several European countries.
Netelia producta is a species of ichneumonid wasp in the subfamily Tryphoninae found in Australia.
