桑蚕雌蛾冷藏对其F1代蚕综合性状的影响研究
The Impact of Cold Storage on Comprehensive Traits of F1 Silkworms
摘要
Abstract
To investigate the impact of cold storage on comprehensive traits of F1 generation silkworms derived from female silkworms of the'827×Xinhang'hybrid strain,comparative trials on cocoon induction and rearing were conducted using first-generation hybrids produced after cold storage at 7.5℃and 10℃.The results demonstrated that prolonged cold storage at 7.5℃had no negative effects on larval viability or economic cocoon traits in F1 generation silkworms.However,under 10℃storage conditions,significant differ-ences were observed across different cold storage periods regarding the number of 4th-5th instar larvae,cocoon formation rate of 4th instar silkworms,healthy pupal retention rate,and cocoon layer quantity.In conclusion,cold storage of midline silkworm females with-in the 7.5℃to 10℃temperature range was feasible for seed production,with the resulting first-generation hybrids proving fully practical for agricultural applications.The optimal temperature standard for midline silkworm females during cold storage was 7.5℃.When using 10℃storage,the protection duration should not exceed 48 hours,with 24 hours being the most effective duration.关键词
