Schizandra chinensis is one of the local special crops grown in Mungyeong, more than 70% of Gyeongbuk area. Scirtothrips dorsalis(Hood) are the most damaging pests among the insects that occur in the Schizandra chinensis, mainly affecting fruit quality, yield and quality. Therefore, it is necessary to study how to reduce the damages by establishing efficient forecasting method and pesticide control system for the Scirtothrips dorsalis(Hood) occurring in Schizandra chinensis. Scirtothrips dorsalis(Hood) was surveyed with yellow sticky traps from April to September in the Mungyeong area. Scirtothrips dorsalis(Hood) has the highest density in July, beginning in early May, and then again in September. Therefore, the suitable time to control the Scirtothrips dorsalis(Hood) is in late May, early July, and mid August. Three species of pesticides(Spinetoram WG, Emamectin benzoate EC, Chlorfenapyr EC) registered in Scirtothrips dorsalis(Hood) were treated three times at the suitable time, as a result of the treatment, a high effect of 92% more.
