摘　　要：将接蜂后的柞蚕蛹保存在低温环境中,诱导白蛾周氏啮小蜂滞育,控制滞育时间,利用公式计算出不同滞育时间下白蛾周氏啮小蜂的发育起点温度(C)和有效积温(K).研究结果显示出蜂率随滞育时间延长而逐渐降低,发育起点温度(C)随着滞育时间的延长而降低,有效积温(K)随着时间的延长而缓步升高.这些数据可为进一步研究白蛾周氏啮小蜂的长期储存技术以及正确把握放蜂时机提供理论依据.The tussah pupa after the beekeeping were preserved in low temperature,in order to make the pupa of Chouioia cunea Yang on diapause induction.The purposes of the study is to calculate the developmental threshold temperature(C)and effective accumulated temperature(K)of different diapause days.The result shows that the eclosion ratio of C.cunea Yang is gradually reducing,the developmental threshold temperature(C)is decreasing,and theeffective accumulated temperature(K)is slowly increasing with the extension of time.These results provide a theoretical basis for the technology of long-term preservation and releasing time of C.cunea.
