The Aphidiinae are a subfamily of tiny parasitoid wasps that use aphids as their hosts. Several species have been used in biological control programs of various aphids.
Aphidiines are koinobiont endoparasitoids of adult and immature aphids. While the larva of the 2–3 mm long Praon leaves the hollowed shell of the aphid from below to pupate in a volcano-like cocoon, most other Aphidiinae pupate inside the dead aphid and break out afterwards.
These wasps are found worldwide, but are primarily found in the northern hemisphere. Several species have been introduced to countries outside of their natural range, both accidentally and purposefully for biocontrol. [1]
Although they have often been treated as a separate family, the Aphidiidae, the Aphidiinae are a lineage within the Braconidae. It is not yet clear to which braconid subfamilies they are most closely related.

Aphidiinae relationships (after Shi & Chen 2005) |
The Aphidiinae are subdivided into several tribes, the Ephedrini, Praini, Trioxini, Aclitini, and Aphidiini, with the latter subdivided into three subtribes. [2] Most species reside in the Aphidiini. The Praini's loss of internal pupation is likely to be secondary. [3]
There are ~400 spp. in ~50 genera worldwide.

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 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 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. More rarely, parasitoid wasps may use plant seeds as hosts, such as Torymus druparum.
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 Cheloninae are a cosmopolitan subfamily of braconid parasitoid wasps.
The Doryctinae or doryctine wasps are a large subfamily of braconid parasitic wasps (Braconidae). Numerous genera and species formerly unknown to science are being described every year. This subfamily is presumably part of a clade containing otherwise any or all of the Alysiinae, Braconinae, Gnamptodontinae, Opiinae and Ypsistocerinae, and might be most closely related to the last one of these. Whether the Rogadinae are also part of this group is not known.
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.
Pauesia is a genus of parasitoid wasps in the subfamily Aphidiinae. The species in the genus use the conifer aphids as their host.
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.
Aphidius nigripes is a species of parasitoid wasp in the subfamily Aphidiinae of the family Braconidae. It is the most common parasitoid of the potato aphid Macrosiphum euphorbiae in eastern North America. Many other species of aphids may also serve as hosts.
The Alysiinae are a subfamily of braconid parasitoid wasps with over 1000 described species. Several species have been used in biocontrol programs. They are closely related to the Opiinae.
The Rogadinae are a large subfamily of braconid parasitoid wasps. Several Rogadinae species parasitize pest caterpillars and are important for naturally occurring biological control.
The Cenocoeliinae are a subfamily of braconid parasitoid wasps.
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.
The Homolobinae are a subfamily of braconid parasitoid wasps. The subfamily Charmontinae was previously included within Homolobinae as the tribe Charmontini.
Dirrhope is the only extant genus in the subfamily Dirrhopinae of braconid parasitoid wasps. Dirrope was included in the Microgastrinae until 1984. Specimens of this genus have been found fossilsed in amber dating from the Cretaceous period.
Aerophilus is a genus of parasitoid wasps belonging to the family Braconidae. As members of the subfamily Agathidinae, they are koinobiont endoparasitoids of caterpillars. The host is attacked as an early instar, but not consumed and killed until the host is about to pupate. Nearly all species of Aerophilus have a narrow host range, attacking only one caterpillar species. However, the host range of the genus as a whole is quite broad, including many families of Lepidoptera.
Meteorinae is a subfamily of braconid parasitoid wasps; however, since 2015, most scientists have treated this clade as the Tribe Meteorini in Euphorinae. 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.
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.
Aphidius is a genus of insects of the family Braconidae.
