The present study was undertaken with specific objectives to assess economic loss in sugarcane due to white grub infestation. The study was conducted in 3 districts of northern Karnataka, viz. Belagavi, Bagalkot and Vijayapur Stratified random sampling method was employed for the farmers. The primary data were collected from 120 farmers’ field with white grub infested sugarcane crop (FFWWGNISC) and 24 farmers’ field with white grub non-infested sugarcane crop (FFWWGNISC). Study revealed that Input used was more in case of FFWWGISC as compared to FFWWGNISC and yield realized by the FFWWGISC (105 t/ha) was lesser when compared to FFWWGNISC (139.58 t/ha). The total variable cost incurred by the FFWWGISC ( 1, 14, 988 /ha) was higher as compared to FFWWGNISC ( 93, 215.51/ha). Net return by the FFWWGNISC found to be less ( 60, 292. 45/ha) than the FFWWGNISC ( 1, 38, 950.74/ha). Net loss realized was due to the white grub in FFWWGISC (- 48,257/ha) as compared to FFWWGNISC.
