Closterocerus
Closterocerus is a genus of minute parasitoid wasps in the family Eulophidae (Hymenoptera). Species within this genus are predominantly larval parasitoids of various insect hosts, including leafmining Lepidoptera, Chrysomelidae beetles, and gall-forming Eulophidae. Several species have been documented as effective biological control agents, particularly against invasive pests. The genus exhibits considerable diversity in host associations and geographic distribution across multiple continents.
Olesicampe
Olesicampe is a genus of ichneumonid wasps containing at least 130 described species. Species in this genus are parasitoids of sawfly larvae (Hymenoptera: Symphyta), with documented associations to hosts in the genera Pristiphora and Cephalcia. Several species have been introduced as classical biological control agents against larch sawfly and mountain ash sawfly pests in North America, where they have established successfully and achieved significant host population suppression. The genus is native to the Palaearctic region.
