Abstract
Arthropods are the major part of the fauna on earth, they participate significantly in sustaining agricultural ecological systems.
Their participation makes them functional bioindicators for determining agro-ecosystem stability. Yet, their abundance and
diversity in some terrestrial ecosystems are still undisclosed. This study was done to determine the diversity of arthropod fauna
in a mixed agroecosystem of District Faisalabad, Pakistan. Additionally, it was compared and analyzed the diversity,
abundance, and richness of species in the Morning and Evening periods. A total of 172 species belonging from 10 orders,70
families, and 2741 specimens were collected from the agroecosystem. The diversity parameters used to analyze the diversity
of arthropods were Shannon index, Evenness Margalef index, Simpson index, and Sorenson similarity index. We observed
that most abundantly found orders were Orthoptera, Diptera, and Hemiptera. Morning fauna exhibited the highest diversity
than evening. The arthropod's abundance differed significantly in the morning and evening. From the overall study, it was
observed that fauna has a great association with the agro-ecological zones. Further research work of a broad level is needed to
explore the more prevalence of fauna in this area, which will be helpful in the management strategies of IPM and crop rotations.
