Abstract: Soil samples were collected from four different types of sites –agricultural field, river basin, brick field and forest floor. Density and group diversity varied considerably among the sites, the statistically significant difference in mean abundance both for total microarthropods and acarines however existed only between forest site and brick field, difference of group diversity was not significant. All the sites showed post-monsoon population maxima. Oribatids were the single largest order at the sites followed by collembolans.
