Diptera-parasitoid
Guides
Alysiinae
Alysiinae are a subfamily of braconid parasitoid wasps containing over 1000 described species worldwide. They are koinobiont endoparasitoids of Cyclorrhapha Diptera, with females ovipositing into host eggs or larvae and killing the host at the puparium stage. Several species have been utilized in biocontrol programs. They are closely related to the Opiinae.
Alysiini
Alysiini is a tribe of koinobiont endoparasitoid wasps within the subfamily Alysiinae (Braconidae). Members are characterized by a distinctive exodont mandible condition—the only group of Braconidae with mandibles that open outward rather than downward. The tribe includes approximately 16 genera in the Dapsilarthra genus group and numerous other genera globally, with substantial faunas in Europe (over 400 species in related Dacnusini) and Australia (14 genera). Host associations are primarily with cyclorrhaphan Diptera, including leaf-mining Agromyzidae, fungus-inhabiting flies, and gall-forming Chloropidae.
Aphaereta
Aphaereta is a cosmopolitan genus of braconid wasps in the tribe Alysiini, comprising approximately 48 described species worldwide. Members are endoparasitoids of Diptera, with documented associations including dung-breeding flies, blow flies, shore flies, and fruit flies. The genus has been recorded across multiple continents including Europe, Asia, North America, South America, and Oceania. Several species have been studied for their potential in biological control programs targeting pest flies.
Brachymeria podagrica
Brachymeria podagrica is a cosmopolitan parasitoid wasp in the family Chalcididae, known from Brazil, Saudi Arabia, Colombia, and multiple other regions worldwide. The species is a solitary idiobiont parasitoid of dipteran pupae, particularly flesh flies (Sarcophagidae) and blow flies (Calliphoridae). It has been documented attacking Sarcodexia lambens, Peckia collusor, Hemilucilia flavifacies, Chrysomya albiceps, and Sarcophaga dux, among other hosts. Development from egg to adult emergence takes approximately 20–27 days under favorable conditions, with overwintering generations requiring 155–180 days. Adults are commonly observed near aphid colonies feeding on honeydew, and occasionally visit flowers such as wild carrot. The species has forensic significance due to its predictable emergence from fly pupae on decomposing corpses.
Diapria
Diapria is a genus of minute parasitoid wasps in the family Diapriidae. These insects are primarily known as parasitoids of Diptera larvae, particularly those developing in decaying organic matter. The genus has been recorded from northern Europe including Denmark, Norway, and Sweden. Taxonomic placement has been historically unstable, with some sources formerly placing species in Chalcididae.
Diapriidae
Diapriidae is a family of minute parasitoid wasps in the order Hymenoptera. Adults range from 1–8 mm in length, with most species measuring 2–4 mm. The family contains approximately 2,300 described species in around 150–200 genera, though estimates suggest at least 4,500 species exist globally. Members are primarily parasitoids of Diptera larvae and pupae, with some species attacking Coleoptera or associated with ants. The family exhibits considerable morphological diversity, including frequent winglessness and pronounced sexual dimorphism.
Diapriini
Diapriini is a tribe of parasitoid wasps within the family Diapriidae. Members are small, slender wasps with reduced wing venation characteristic of the family. They are primarily known as parasitoids of Diptera larvae, particularly in soil and decaying organic matter habitats. The tribe is cosmopolitan in distribution with substantial representation in temperate regions.
Dirhinus
Dirhinus is a genus of chalcidid wasps comprising approximately 70 described species with worldwide distribution. These wasps are pupal parasitoids of Diptera, particularly flies associated with decomposing vertebrate matter, including synanthropic species such as house flies, blow flies, and flesh flies, as well as agricultural pests like fruit flies. Females locate host pupae in soil or substrate by digging with their horns and oviposit directly on the pupa within its puparium. Several species, notably Dirhinus giffardii, have been investigated for biological control applications against filth flies and fruit fly pests.
Tachinaephagus zealandicus
Tachinaephagus zealandicus is a gregarious larval-pupal endoparasitoid wasp in the family Encyrtidae. It parasitizes larvae of synanthropic Diptera, particularly muscoid flies including Musca domestica and various Calliphoridae species associated with decomposing carrion. The species has been studied extensively for its potential in forensic entomology and biological control. Under laboratory conditions at 25°C, its life cycle completes in 23–27 days, with single hosts producing 3–18 adult parasitoids.
Zaeucoila robusta
Zaeucoila robusta is a species of parasitoid wasp in the family Figitidae, subfamily Eucoilinae. First described by Ashmead in 1894 as Chrestosema robusta, this species is now placed in the genus Zaeucoila. Members of this genus are known as figitid wasps that parasitize dipteran larvae, particularly those associated with decaying organic matter. The species has been recorded from Brazil and Canada.
