【Abstract】 [Objective] To control the non-diapause eggs occurrence on the spring original species Yuncan 8 A×B.[Method] Combining with the related research,species characteristics and actual production,inducements of the non-diapause eggs occurrence were analyzed,then different measures were adopted to control it.[Result] In recent years,the ratio of non-diapause eggs in spring original species Yuncan 8 A×B reduced from 10%-15% to 1%-2%.[Conclusion] Several measures,including species property selection,management in the incubation period,rearing environment and nutrition conditions in larval phase,proper protection in pupal phase,could effectively control the non-diapause eggs occurrence on the spring original species Yuncan 8 A×B.更多还原
