Ground beetles are important bioindicators of the habitat and its study helps in insect and weeds management at the farms. A study was carried out in the 2017-2020 to measure the biodiversity and impact of urbanization on the ground beetles. Ground beetles were collected by pit fall, observations and by mechanical methods from four experimental sites - two from urban area and two from the suburban area. The results obtained after running the data on PAST Version 4.03, the Shannon diversity index of the urban area is lower than the suburban area. The percentage of collection of the ground beetles were 25 percent from urban area while, 75 per cent from the suburban area. The result of t-Test and Cochran Q Test also were significant to infer the difference between the two sites - urban and suburban are different.
