Abstract: This study was conducted to determine the species compositions and relative abundance of soil arthropods in Leventis agricultural training school maize farmland Yaba, FCT, Abuja Nigeria from 28th of January, 2018 to December 28th, 2018. Soil arthropods were sampled using pitfall trap of height of 14.40cm and diameter 9.50cm with an overlap cover of 11.00cm held attached to the trap by two iron rod of length 1.65cm. A total of 3202 soil arthropods were sampled belonging to 7 orders, 8 families and 35 species. The Order Coleoptera had the dominant taxa of 3099 (96.78%), while Orthoptera had the least taxa of 25 (0.78%). In terms of family dominance, Scarabaeidae had the highest taxa of 2067(64.96%) while Buprestidae, Acrididae, Lygaeidae and Tiphiidae has the least taxa of 1(0.03%). In species dominance, Hister monitor (Lewis) had the highest of 901 (28.14%) followed by Copris sp. 879 (27.45%) and Gymnopleurus fulgidus 719 (22.45%). In the Monthly sampling, the month of June had the highest number of taxa 2016 (62.96%) followed by the month of May 381(11.91%), while the month of December had the least number of taxa 1(0.03%). From these results, it was observed that stable rainfall and vegetation are good predictors of soil arthropods abundance in a particular farmland.
