Aphidiinae
Guides
Adialytus
A genus of aphid parasitoid wasps in the family Braconidae, subfamily Aphidiinae. Species within this genus are solitary, koinobiont endoparasitoids of aphids (Aphididae), developing within living hosts. The genus is represented by four species in Europe, with records from Turkey, Ukraine, and Scandinavia. Members are of economic interest as potential biological control agents of pest aphids on crops and woody plants.
Diaeretiella
Diaeretiella is a monotypic genus of parasitoid wasps in the family Braconidae, subfamily Aphidiinae. The sole species, Diaeretiella rapae, is a cosmopolitan koinobiont endoparasitoid of aphids with documented occurrence in 87 countries. It has been recorded parasitizing approximately 98 aphid species across more than 180 plant species in 43 plant families, with particular association to cabbage aphid (Brevicoryne brassicae) on cruciferous crops. The genus is recognized as an important biological control agent in integrated pest management systems.
Ephedrini
Ephedrini is a tribe of koinobiont aphid parasitoids within the subfamily Aphidiinae (Braconidae). The tribe comprises approximately 29 species in India, including genera such as Ephedrus and Toxares. Members are exclusively endoparasitoids of aphids, with some species exhibiting extreme polyphagy—Toxares deltiger parasitizes 27 aphid species and Ephedrus plagiator parasitizes 22. Several species have been successfully employed in biological control programs worldwide.
Ephedrus
Ephedrus is a genus of small braconid wasps in the subfamily Aphidiinae, all species of which are obligate parasitoids of aphids. The genus includes both extant and fossil species, with records from the Eocene Baltic amber indicating an ancient evolutionary history. Multiple species have been evaluated or employed as biological control agents against agricultural pest aphids, particularly in greenhouse systems. Species-level studies reveal complex host discrimination behaviors involving external marking pheromones and internal host quality assessment.
Monoctonina
Monoctonina is a subtribe of aphid parasitoid wasps within the subfamily Aphidiinae (Braconidae). Members are small parasitic wasps that develop within aphid hosts, eventually killing them. The subtribe includes genera such as Monoctonus and Falciconus, with species documented from high-elevation mountain habitats in Europe and Asia.
Monoctonus
Monoctonus is a genus of solitary parasitoid wasps in the subfamily Aphidiinae (Braconidae). Species in this genus are specialized parasitoids of aphids, with females laying eggs in the thoracic nerve ganglia of host aphids. Multiple species have been documented, including M. paulensis, M. nervosus, M. paludum, and M. leclanti, with distributions spanning the Palearctic, Nearctic, and Oriental regions.
Trioxys
Trioxys is a genus of aphid parasitoid wasps in the subfamily Aphidiinae (Braconidae). Species within this genus are internal parasitoids of aphids and have been studied for their biological control potential against agricultural pests. Some species, such as T. indicus, exhibit adaptive learning in host discrimination behavior, with experience reducing superparasitism and improving oviposition efficiency. Other species, including T. utilis and T. pallidus, have been deployed or studied for management of specific aphid pests in crops such as alfalfa and hazelnut.
