Role of different abiotic factors on the temporal fluctuations of shoot and fruit infestation by Earias vittella on okra crop were studied under field conditions at Vegetable Research Farm, Banaras Hind University, Varanasi during Kharif season 2014-15 and 2015-16. Shoot infestation was observed during 37th SW (one month after sowing) where as fruit infestation was observed during 39th SW (6 weeks after sowing). The maximum shoot infestation has been observed at 40th SW while fruit infestation was maximum at 42nd S.W. Thereafter, fruit infestation was gradually declined but persisted up to third week of November. Further, shoot infestation found to have significant positive correlation with morning R.H. during 2014-15 cropping season and maximum temperature during 2015-16. Other weather parameters did not significantly influence the shoot borer damage. Further, weather parameters did not significantly influence the fruit damage by the borer during both the years.
