Blacus ruficornis
Blacus ruficornis is a species of parasitoid wasp in the family Braconidae, subfamily Blacinae. The species was first described by Christian Gottfried Daniel Nees von Esenbeck in 1811. It belongs to a genus characterized by specific morphological traits including reduced wing venation and particular antennal structures. Records indicate presence in Northern Europe and on Madeira Island.
Pygostolus
Pygostolus is a genus of braconid wasps in the subfamily Blacinae, comprising approximately eight described species. The genus is best known through studies of P. falcatus, an endoparasitoid of weevils in the genus Sitona. These wasps exhibit thelytokous parthenogenesis and develop as solitary endoparasitoids within the haemocoele of their hosts. The genus has been investigated for biological control applications, particularly against sweetclover weevil (Sitona cylindricollis), though effectiveness is limited by phenological asynchrony and diapause.
