The survey of aphids and their parasitoids in various ecosystems of the Northwestern region of Algeria revealed the presence of 25 species of aphids belonging to subfamily Aphidinae with two tribes and eleven genera. Aphid individuals were collected from 46 host plant species belonging to 22 plant families, Aphis fabae was the most abundantly detected aphid species in this area. Seven primary parasitoid species that have been identified belonged to the family of Braconidae and were divided into three genera (Aphidius, Lysiphlebus and Diaeretiella). The wasp Lysiphlebus testaceipes, was the most frequent species. The parasitoids species with their host aphids and flora in diverse habitats formed 54 Tri-trophic interactions.
