White grubs are the major insect pests of cultivated plants in semi arid agro-ecosystem of Rajasthan. It is important to understand diversity, abundance and distribution of scarabaeid beetles for planning effective pest management programme. The experimental data were collected from nine locations in three different ecosystems in Kharif season of year 2019. Species identification revealed that there was total nine species were recorded from 18885 specimens collected. The identified species were belongs under two subfamilies of Scarabaeidae family. Maximum specimens were collected in the month of July from selected sites. When species diversity was compared among different locations, it was found that Shannon Wiener diversity index varied from 1.235 to 1.095, which indicates that species were less diverse but frequently present. The present study can be used to formulate the integrated pest management strategies based on most abundance and diverse scarabaeids in semi-arid agro-ecosystem of Rajasthan.
