Abstract
The present investigation was carried out during kharif season 2023 at Agricultural Research Farm of RBS College Bichpuri, Agra (Uttar Pradesh). During the investigation, it has been revealed that the infestation of the shoot and fruit borer, Earias vittella (Fab.) on okra during the kharif season commenced from shoots 31th SMW (3.20%) and fruit borer 35th SMW (3.20%). The infestation ranged from shoot (3.20 - 29.70%) and fruit borer (3.20 - 36.42%), with the peak occurring in the 36th (29.70) and 39th (36.42) SMW and continuing until harvesting. The percentage of shoot and fruit borer infestation has a positive significant correlation with maximum temperature, minimum temperature, evening relative humidity and wind velocity. However, morning relative humidity, rainfall and sunshine hour has a negative significant correlation during kharif season 2023.
