Infestation on fruit starts in 37th standard week (September second week) with an average population of 3.31% infestation. The shoot and fruit borer population increased and gradually reached its peak level of infestation 5.71% at 41st standard week (October second week). The population of shoot and fruit borer decreased with infestation of 2.26 % at 45th standard week (November 1st week) there after declined trend was observed as temperature decreased. The shoot and fruit borer population increased with increasing temperature and positively correlated with maximum temperature.
