Description
Summary:This study was conducted in the natural environment of the Khenchela region. Different prospections allowed the collection a total of 8 species of primary parasitoids (Hymenoptera: Braconidae, Aphidiinae), which were able form 22 tri-trophic associations with 12 aphid species and 14 plant species. The kind Aphidius is best represented the species Aphidius funebris was able to emerge from the mummies of 6 aphid species. This primary parasitoid expressed a preference for aphids kind Uroleucon. The largest rate of emergence was obtained from the parasitoid Lysiphlebus fabarum, while Hyperomyzus aphids lactucae and Brachycaudus cardui are the most infected.
