In the wheat agroecosystem, 42 species of arthropods from 26 families and 10 orders were found. In terms of population frequency in the wheat agroecosystem, arthropod diversity revealed that the corn leaf aphid, Rhopalosiphum maids (18.85%), was the most common, followed by the bird cherry oat aphid, Sitobion avenae (7.76%), and the lady beetle, Coccinella transversalis (4.80%). The most dominant order was Coleoptera with relative abundance of (30.95%) and the least was Orthoptera, Neuroptera and Isoptera (2.38%). Arthropod diversity was measured using indicators such as the Gini-Simpson index and the effective number of species. Using the Shannon-Weiner index and the Gini-Simpson index, the effective number of species for the arthropod community on wheat was 0.059 and 3.341, respectively. As a result, this study emphasises the diversity and abundance of arthropod fauna, as well as the importance of long-term conservation efforts.
