Abstract: The duration of. low temperature storage Influenced the survival and fecundity of the overwintered adults. The survival rate varied between 11.9-31.1%, when adults underwent storage under 4-6℃ for 57-146 days. The survival rate curve followed Deevey'sⅢ type. Each individual laid 224.9,118 and 68.6 eggs after being kept under 4-6℃ for 73, 92 and 146 days, respectively. The oviposition peak after the storage occurred earlier than those experienced no storage.
