Abstarct: Using natural enemies as a supplement or alternative for chemical control or along with other methods to control aphids have long been done to eliminate the damages of this group of pests. The main purpose of the study was to identify the themes for biological control of aphids using their parasitoids taking into account the fact that irregular use of chemical toxins results in increasing the expenses of production, bringing up hygienic and environmental issues, and making resistance in insects. Insects are prone to attacks from a large number of natural enemies including predators, parasitoids, and other pathogens, and hence identifying existing species and their biodiversity are of great importance. baxsed on the samplings done in 2020-2021 in Neyshabur, Iran, more than 100 samples of parasitized aphids were collected which were comprised of four genera including Lysiphelebus, Binodoxys, Adialyts, and Aphidius, and seven species including L.confusus, L.fabarum A, A.ambiguus, A.salicaphis, B.angelicae, A.smithi, and A.matricariae, among which Lysiphlebus fabarum was labeled as the purely dominant species having frequency of 30 percent, and Binodoxys angelicae were labeled as the dominant spieces having frequency of 10-30 percent, and Adialytus salicaphis, Adialytus ambiguous were labeled as the semi-dominant spieces having frequency of 5-10 percent. In Shannon-Wiener Index L.fabarum constitutes the most percentage. In Simpson Index, the highest percentage belongs to , B.angelicae, and in Margalef Index, L.confusus has the highest percentage. in all three indicators Agricultural vegetation has a significant advantage over the other two. Among the covers and climates, the highest and lowest frequency were for garden cover and vegetation, respectively.
