The light trap studies were conducted at five different locations, viz. Jaipur, Phagi, Amer, Chomu and Shahpura in Jaipur district of Rajasthan during kharif seasons of 2018 and 2019. At survey locations the maximum mean grub population in the soil was observed at Chomu tehsil (4.30±0.36 /ft3) followed by Jaipur tehsil (4.00±0.44 /ft3) and Phagi tehsil (2.75±.55 /ft3) at 100 per cent frequency with mean per cent infestation of 44.39, 38.95 and 35.57 per cent, respectively due to white grub. Minimum mean grub population (2.45±0.53 /ft3) as well as percent infestation (27.44%) due to white grub was observed at Shapura tehsil.
