The prospections undertaken in Biskra permitted to investigate the biodiversty of parasitoids of the Aphidiinae family.Parasitoids were collected in 19 different localities on aphids associated with various host plants. All specimens were reared from the natural habitats and preserved in 70% ethanol. This study documented 14 species belonging to 6 genera: Aphidius genus (5species), Binodoxys genus (2species), Diaeretiella genus (1specie), Lysiphlebus genus (3species), Praon genus (2species), Trioxys genus (1specie). All those parasitoids were collected from 24 aphid taxa occurring on 32 plant taxa and 60 parasitoid-aphid associations are reported. Host plants belong to 14 botanical families. The Asteraceae and the Fabaceae constitue the families with the largest number of associated parasitoid species. The present survey permitted to enrich the biodiversity of the Aphidiinae family of Algeria.
