Meteorinae is a subfamily of braconid parasitoid wasps. 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. [1]
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. [1]
They are found worldwide, in habitats where their hosts can be found. [1]
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. [1]
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. [2]
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. [3] M. vesicolor was introduced to the United States in the early 1900s for the control of the brown-tail moth. [4] M. trachynotus was investigated for control of spruce budworm [5] as was M. hypophloei for controlling bark beetles. [6] Other species have been used in control of cutworms, avocado looper, and swallowtail pests on citrus crops. [1]
Lymantria dispar, known as the gypsy moth, or the spongy moth, is a species of moth in the family Erebidae. Lymantria dispar is subdivided into several subspecies, with subspecies such as L. d. dispar and L. d. japonica being clearly identifiable without ambiguity. Lymantria dispar has been introduced to several continents and is now found in Europe, Africa, Asia, North America and South America. The polyphagous larvae live on a variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, Lymantria dispar is listed among the world's 100 worst invasive alien species.
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 Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
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.
The Ichneumonidae, also known as the ichneumon wasps, Darwin wasps, or ichneumonids, 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 currently described. 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. Ichneumonid wasps, with very few exceptions, attack the immature stages of 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 control.
The Tortricidae are a family of moths, commonly known as tortrix moths or leafroller moths, in the order Lepidoptera. This large family has over 11,000 species described, and is the sole member of the superfamily Tortricoidea, although the genus Heliocosma is sometimes placed within this superfamily. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting posture is with the wings folded back, producing a rather rounded profile.
The Tephritidae are one of two fly families referred to as fruit flies, the other family being the Drosophilidae. The family Tephritidae does not include the biological model organisms of the genus Drosophila, which is often called the "common fruit fly". Nearly 5,000 described species of tephritid fruit fly are categorized in almost 500 genera of the Tephritidae. Description, recategorization, and genetic analyses are constantly changing the taxonomy of this family. To distinguish them from the Drosophilidae, the Tephritidae are sometimes called peacock flies, in reference to their elaborate and colorful markings. The name comes from the Greek τεφρος, tephros, meaning "ash grey". They are found in all the biogeographic realms.
Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs. Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over 200 species worldwide.
Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. A larva typically attacks the first part of the plant it encounters, namely the stem, often of a seedling, and consequently cuts it down; hence the name cutworm. Cutworms are not worms, biologically speaking, but caterpillars.
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.
Choristoneura fumiferana, the eastern spruce budworm, is a species of moth of the family Tortricidae native to the eastern United States and Canada. The caterpillars feed on the needles of spruce and fir trees. Eastern spruce budworm populations can experience significant oscillations, with large outbreaks sometimes resulting in wide scale tree mortality. The first recorded outbreaks of the spruce budworm in the United States occurred in about 1807, and since 1909 there have been waves of budworm outbreaks throughout the eastern United States and Canada. In Canada, the major outbreaks occurred in periods circa 1910–20, c. 1940–50, and c. 1970–80, each of which impacted millions of hectares of forest. Longer-term tree-ring studies suggest that spruce budworm outbreaks have been recurring approximately every three decades since the 16th century, and paleoecological studies suggest the spruce budworm has been breaking out in eastern North America for thousands of years.
Glyptapanteles is a genus of endoparasitoid wasps found in Central and North America and New Zealand. The larvae of the members of Glyptapanteles sp. are distinguished by their ability 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.
Chloridea virescens, commonly known as the tobacco budworm, is a moth of the family Noctuidae found throughout the eastern and southwestern United States along with parts of Central America and South America.
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 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.
Cotesia rubecula is a parasitoid wasp from the large wasp family Braconidae.
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.
