为掌握桑蚕雌蛾的耐冷藏性和冷藏后的交配产卵效果，在5℃条件下对桑蚕两广二号、贵蚕一号雌蛾进行了不同时间冷藏后的交配产卵试验。结果表明，在温度5℃和相对湿度75％条件下冷藏，桑蚕雌蛾的耐冷藏性因品种不同有差异。含多化性血统的两广二号原蚕9·芙和7·湘较耐冷藏，冷藏72 h以内交配能力仍然较强。产卵效果因品种和时间不同也有差异。在5℃条件下，两广二号9·芙原蚕雌蛾冷藏时间在24 h以内最好，7·湘原蚕雌蛾冷藏时间在72 h以内实用，贵蚕一号新杭原蚕雌蛾以不冷藏最好，826原蚕雌蛾冷藏时间在48 h以内最好。

In order to investigate the resistance of female silkworm moths to cold storage and their copulation and oviposition after cold storage, copulation and ovipo-sition experiments of Liangguang 2 silkworms and Guican 1 female silkworm moths were conduced under cold storage at 5 ℃ for different durations. The results indi-cated that, after cold storage at 5 ℃ with relative humidity of 75%, the resistance of female silkworm moths to cold storage varied with different varieties; to be specific, 9·Fu and 7·Xiang, parent silkworm varieties of Liangguang 2 with ancestry of mul-tivoltinism, were relatively resistant to cold storage, and their copulation capability was stil at a high level after cold storage for 72 h. Oviposition capability also varied with different varieties and durations; to be specific, under 5 ℃ conditions, between two parent silkworm varieties of Liangguang 2, female silkworm moths of 9 ·Fu achieved the best results within cold storage duration of 24 h, female silkworm moths of 7·Xiang achieved the best results within cold storage duration of 72 h; be-tween two parent silkworm varieties of Guican 1, female silkworm moths of Xinhang achieved the best results without cold storage, female silkworm moths of 826 achieved the best results within cold storage duration of 48 h.
