The present investigation was conducted to study the effect of abiotic factors on occurrence of leaf folder, Cnaphalocrocis medinalis Guenee in basmati rice in western plain zone of Uttar Pradesh during Kharif 2017 and 2018. Observations of C. medinalis infestation were recorded at weekly interval, 15 days after transplanting till harvesting. The peak period of pooled maximum leaf damage (13.40%) of both cropping seasons was recorded in 39th standard week. Thereafter, infestation declined gradually. The correlation matrix between infestation of leaf folder with weather parameters indicated that there was a positive correlation with maximum temperature (r= 0.38), minimum temperature (r= 0.50), morning relative humidity (r= 0.01), evening relative humidity (r= 0.70) and rainfall (r= 0.13) with the leaf damage caused by leaf folder.
