Studies were carried out on “Seasonal incidence and management of okra shoot and fruit borer, Earias vittella (Fabricius)” on okra (GAO 5) at N. M. College of Agriculture, Navsari Agricultural University, Navsari during summer 2022. The shoot infestation commenced from 4^th week after sowing (9^th SMW) with maximum (25.71%) in 9^th week after sowing (14^th SMW). Whereas, fruit infestation noticed from 6th week after sowing (11^th SMW) with maximum (40.20%) in 11^th week after sowing (16^th SMW). Shoot damage showed positive and significant correlation with maximum temperature (0.509), while fruit damage was found positive and highly significant correlation with minimum temperature (0.685). Shoot damage exhibited negative and non-significant correlation with morning relative humidity (-0.030) and wind velocity (-0.286). Among the different insecticides, spinosad 45 SC (0.018%) was the best treatment and recorded significantly lowest fruit damage (8.05%), which was at par with chlorantraniliprole 18.5 SC (0.005%) and lambda-cyhalothrin 4.90 CS (0.003%) having 8.85 and 9.17 per cent fruit damage, respectively. Treatment pyridalyl 10 EC (0.01%) was found least effective against fruit borer (13.96%).
