【 摘 要 】

This study was conducted to determine the abundance and diversity of soilarthropods in Anua and Ekpri Nsukara farmland communities, Uyo, Nigeria from Septemberto November, 2012. Soil arthropods were sampled using pitfall trap. A total of 707Individuals of soil arthropods were encountered during the study period. Of the total number,203 individuals were encountered in Anua while 504 in Ekpri Nsukara. Hymenoptera werethe dominant taxa while the least was Blattodea in the two communities. Higher Shannondiversity index 1.3 was recorded in Anua while lower diversity index 0.86 was recorded inEkpri Nsukara. Evenness ranged from 0.006 to 0.80 in Ekpri Nsukara and 0.02 to 0.61 inAnua. The lower abundance of soil arthropod in Anua community as compared to EkpriNsukara could be attributed to the partially open vegetation which exposes the arthropods toavoidable predators.
