Currently, Carposina sasakii (peach fruit moth) is considered economically important pest in organic jujube orchards. However, until now, research has not been conducted to control C. sasakii. The control period is very important for moth larvae to contact organic materials. Therefore, this study were conducted to determine when control using organic materials selected in 2017. In the method, parafin oil selected in 2017 was treated seven times at interval of seven days, and each treatment interval was seven days until 7th treatment. As a result, when the control started at the early to mid July, the control values were about 75%, and when the control started at late July to mid August, the control values were over 85%. However, when the control started after mid August, the control value was less than 30%. Therefore, in order to effectively control C. sasakii, control must be started by early August.
