Online Published on 12 September, 2022. Abstract A field experiment was conducted at SASRD, Nagaland University, Nagaland from June 2017 to January 2018 on pigeon pea to find out the species abundance of arthropods fauna by means of pitfall trap for soil surface dwellers. Soil surface dwellers were recorded with a total mean of 16.60 belonging to 23 families and 13 orders comprising Hymenoptera (38.10%), Orthoptera (17.44%), Dermaptera (0.11%), Isoptera (2.05%), Dictyoptera (1.40%), Hemiptera (0.97%), Coleoptera (16.26%), Diplopoda (4.63%), Chilopoda (1.51%), Acarina (3.34%), Araneida (11.84%), Lepidoptera (0.97%) and Diptera (0.86%). Formicidae (Hymenoptera) was the most dominant group. Correlation with the abiotic factors indicated that maximum and minimum temperature, minimum relative humidity and rainfall were found positively correlated with Hymenoptera, Orthoptera, Coleoptera and Araneida but maximum relative humidity was found to be negatively correlated with Hymenoptera, Coleoptera and Araneida but non-significantly with Orthoptera. The population of arthropods was found to be increased when temperature was high but reached lowest when temperature started to decline in the month of Dec-Jan 2018.
