Seasonal occurrence and distribution of insect pests and their natural enemies were investigated in several Paprika greenhouses(different pest control histories). Even in the environmental-controlled greenhouses with natural enemies for controlling insect pests, there were differences in occurrence and distribution of insect pests and natural enemies by season. From March after planting, aphids and whiteflies(Myzus persicae and Bemisia tabaci) had partially occurred in all experimental greenhouses. During summer season, whiteflies and leaf mites primarily occurred and insect pest species occurred in this season were more diverse than the winter season. In the winter season, whiteflies predominantly occurred in both natural enemies and pesticide-treated Paprika greenhouses. Predatory mite, Amblyseius swirskii was difficult to maintain their populations under an average temperature below 18℃ and relative humidity below 60%.

A key to species from Korea, comments on external and genital structures, biology, illustrationsof structures, including the genitalia of both male and female of the Korean Soronia species are provided.
