The overall mean fruit damage values after first and second spray confirmed the superior efficacy of Spinosad 45% SC, which recorded the lowest fruit damage of (19.18%). It was followed by T6: Spinetoram 11.7 SC with (21.22%) fruit damage and T2: Lambda-cyhalothrin5% EC with 23.60 per cent fruit damage. Moderate levels of control were observed in biopesticide treatments, such as T5: Azadirachtin 10000 PPM with 27.16 per cent fruit damage, T3: Metarhizium anisopliae with 28.23 per cent, and T1: Beauveria bassiana with 29.83 per cent fruit damage.
