The diversity of arthropod fauna of mango ecosystem was studied in Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Union Territory of Puducherry and their population dynamics from August 2016 to February 2017 evaluated. The fauna was collected at weekly intervals with net sweeping method, pitfall traps and in situ counts. The biodiversity analysis with Shannon-Wiener index and Margalef richness index revealed that the diversity was more for Coleoptera (3.0220 and 5.0520); Simpson's index was maximum for Orthoptera (0.1846), and equitability index maximum with Neuroptera (1.00). Among the 127 arthropods observed, the population of
