Background : Most of cases in korea, distributed herbal medications are storaged in room temperature and it causes many insect pests during storage. Despite the fact, there is little research about storage conditions. Temperature and humidity in storehouse are highly related with pests’ overwintering, generation length and the number of occurrence in summer. Consequently, in this research, major pests’ overwintering was studied by reviewing facility condition, temperature and humidity in major regional storehouses. The results of this would help to develop how to manage pest occurrence in distributed herbal medications. Methods and Results : For this study, storage facilities was investigated at different regions including Gyeongdong Market in Seoul, the pharmaceutical company in Daegu and farmhouse in Youngcheon by monitering temperature, humidity, ventilator, air conditioning and heating on ground and underground places from June 2014 to July 2016. including Upon investigation, most of building using for storage had simple ventilators. Whereas in case of farmhouse, it is vulnerable to maintaining quality. Because most farmhouse had temporary buildings which are difficult to control temperature and humidity. In addition, among the other surveyed warehouses, Basement in the Gyeongdong Market had most favorable condition for pest overwintering. The lowest temperature of it was seldom below zero maintaining level of about 1.5℃ and average temperature was about 10℃ in underground warehouse during winter. And the ground warehouse of Daegu had similar patterns in temperature and humidity with that of Seoul in that being over 0℃ even in the winter. In Youngcheon, the temperature of farmhouse was below zero degree and the daily range of temperature and humidity was wide. It caused difficulty of overwintering of insect pests but possible to inhabit. Conclusion : According to a study by Han-Mo, Koo(1997), it was impossible to overwinter for Lasioderma serricorne F. which is dominant medicinal plants’ pest in north of the Chungcheong region’s warehouse due to low temperature. But in case of investigated warehouses, it was possible to overwinter because of the high temperature in office building or basement storage area. In order to make prediction of pest occurrence and comprehensive measures, it is urgent to take more investigation by regional groups and types of storage.
