Investigations on seasonal incidence of okra shoot and fruit borer and its relation with weather parameters in summer okra was carried out at Instructional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh during summer 2016 and 2017. The data on seasonal abundance of Earias vittella on okra showed that, in first season (2016), the pest activity of this noctuid commenced from 11th standard week (0.9 larva/ plant) and continued up to 24th standard week (0.93 larva/ plant) and in next season at 11rd standard week (0.7 larva/ plant) to 24th standard (0.10 larva/ plant). Shoot damage was observed from 11th standard week whereas fruit damage was started during 5th week after sowing during both the years of study. While in correlation study maximum and minimum temperature showed significant positive correlation and bright sunshine showed negative correlation with okra shoot and fruit borer population.
