Endoparasitoid
Guides
Tersilochinae
Tersilochinae is a worldwide subfamily of parasitic wasps within Ichneumonidae, comprising approximately 500 species across 24 genera. Members are koinobiont endoparasitoids that develop within living host larvae, primarily attacking Coleoptera including economically significant families such as Curculionidae and Chrysomelidae. This host specificity has led to their use in biological control programs. The subfamily exhibits broad geographic distribution with documented records from the Palearctic, Nearctic, Afrotropical, Neotropical, and Australasian regions.
Theronia
Theronia is a genus of ichneumon wasps in the family Ichneumonidae, established by Holmgren in 1859. The genus comprises at least 30 described species with a worldwide distribution. Species in this genus are parasitoids, specifically endoparasitoids or hyperparasitoids, of Lepidoptera larvae.
Tranosema
Tranosema is a genus of ichneumonid parasitoid wasps found in Europe and North America. Species in this genus are endoparasitoids of lepidopteran larvae, particularly tortricid moths. The best-studied species, T. rostrale, is a koinobiont parasitoid of the spruce budworm (Choristoneura fumiferana) and transmits a polydnavirus (ichnovirus) to its host during oviposition, which alters host development and physiology.
Triclistus
Triclistus is a genus of ichneumonid wasps comprising at least 90 described species. Members are solitary endoparasitoids of lepidopteran larvae. The genus exhibits competitive interactions with other parasitoid species when hosts are multiply parasitized.
Trogus lapidator
Trogus lapidator is an ichneumonid parasitoid wasp that develops within the pupae of the Old World swallowtail butterfly Papilio machaon. It is notable for an unusual emergence mechanism: rather than cutting through the host pupal case with mandibles like most related wasps, it primarily uses a liquid secretion to soften and dissolve host tissue, employing mandibles only secondarily to spread the secretion and minimally enlarge the exit hole at the end of emergence. The species occurs across Europe, with records from Finland to Belgium and Canada.
Xanthomelanodes
Xanthomelanodes is a genus of tachinid flies comprising 13 described species. As members of the subfamily Phasiinae and tribe Gymnosomatini, these flies are endoparasitoids of true bugs (Hemiptera: Heteroptera). Larvae develop inside their hosts and kill them. The genus was erected by Townsend in 1893 as a replacement name for Xanthomelana Wulp, 1892, which was already in use.
Yelicones pilops
Yelicones pilops is a species of parasitoid wasp in the family Braconidae, described by Quicke and Kruft in 1995. It belongs to the genus Yelicones, a group of braconid wasps characterized by distinctive morphological features. Like other members of its family, it is presumed to be a parasitoid of other insects, though specific host records for this species are not well documented. The species is known from limited collection records.
Zaeucoila
Zaeucoila is a genus of parasitoid wasps in the family Figitidae, established by Ashmead in 1903. Species within this genus are endoparasitoids of leaf-mining flies in the family Agromyzidae (Diptera), including significant agricultural pests such as Liriomyza sativae. The genus has undergone systematic revision to clarify species identities and document host associations. Developmental studies indicate complete immature stages require approximately 22 days, with distinct morphological changes between larval instars.
Zele
Zele is a genus of braconid parasitoid wasps in the subfamily Euphorinae, containing approximately 30 species worldwide. The genus is distinguished by specific wing venation features: presence of vein r-m on the fore wing, a rhomboid or quadrate second submarginal cell of the fore wing, and an apically widened marginal cell on the hind wing. Species are koinobiont endoparasitoids of lepidopteran larvae. The genus is widespread across the Palearctic, Nearctic, and Oriental regions but absent from the Afrotropical and Australian regions.
