Alysiinae
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. Description and distribution Alysiinae are small wasps, usually under 5 mm long and black or brown in color. Their mandibles are exodont, opening outwards and not overlapping. This characteristic is essentially unique among braconids, with only a few rare exceptions (e.g., the genus '' Exodontiella'' in the subfamily Gnamptodontinae). Alysiinae are found worldwide. Biology Alysiinae are koinobiont endoparasitoids of Cyclorrhapha Diptera. Females oviposit into host eggs or larvae. The host is allowed to develop until it forms a puparium, at which point it is killed by the wasp larva. The Alysiinae larva then pupates within the host puparium. Adults use their exodont mandibles to break free of the tough host puparium. Most species of Alysiinae are solitary, but a few are gregarious and ...

Dinotrema
''Dinotrema'' is a genus of wasps in the family Braconidae. Species are amongst the largest parasitoid wasps in the tribe Alysiini (Alysiinae). There are approximately 350 species described around worldwide. Economic significance Generally, ''Dinotrema'' species are parasitoids of the larvae of Diptera predominantly from families Anthomyiidae, Phoridae and Platypezidae, groups considered as pests. Distribution ''Dinotrema'' comprises a large number of species described from Afrotropical, Australasian, Nearctic, Neotropical, Oceanic, Oriental and Palaearctic The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Sibe ... (mainly from Western Europe) regions. Identification This genus has tridentate and small mandibles, with paraclypeal fovea short, not reaching ventral edge of eyes. Vein ...

Asobara
''Asobara'' is a genus of parasitoid wasps in the family Braconidae. The genus is best known for the ''Drosophila'' parasitoid ''Asobara tabida'', which is notable as both a model for parasitoid wasp infection in insects, and also as a representative of the hologenome theory of evolution. ''Asobara tabida'' is commensally infected with ''Wolbachia'', and cannot reproduce in the absence of ''Wolbachia'' infection. As such, the genome of ''Asobara'' is directly tied to the genome of its commensal ''Wolbachia'' symbiont, and the two are considered to have a hologenome The hologenome theory of evolution recasts the individual animal or plant (and other multicellular organisms) as a community or a "holobiont" – the host plus all of its symbiotic microbes. Consequently, the collective genomes of the holobiont for .... References Further reading * *Rolff, J., and A. R. Kraaijeveld.

Opiinae
The Opiinae are a subfamily of braconid parasitoid wasps with over 1300 described species. Several species have been used in biocontrol programs against fruit flies and Agromyzidae flies. They are closely related to the Alysiinae. Description and distribution Opiinae are small wasps, usually under 5mm long. They are non-cyclostomes, but sometimes have the appearance of a cyclostome opening. Unlike Alysiinae, Opiinae have endodont mandibles, which open inwards. Opiinae are found worldwide. Biology Opiinae are koinobiont endoparasitoids of cyclorrhaphus Diptera. Females oviposit into host eggs or larvae. The host is allowed to develop until it forms a puparium A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their ..., at which point it is killed by the wasp larva. References ...

Chorebus
''Chorebus'' is a genus of parasitoid wasps in the family Braconidae. There are around 430 accepted species in the genus. The genus was first described in 1833 by Alexander Henry Haliday Alexander Henry Haliday (1806–1870, also known as Enrico Alessandro Haliday, Alexis Heinrich Haliday, or simply Haliday) was an Irish entomologist. He is primarily known for his work on Hymenoptera, Diptera, and Thysanoptera, but worked on ....
