[Objectives]  To clarify the effects of cold storage time on the survival, parasitism and reproduction of Bracon adoxophyesi Minamikawa,and thereby improve the low-temperature storage of this parasitic wasp. [Methods]  The effect of keeping B. adoxophyesi at 10 ℃ for 30, 45, 60, 75, 90 and 105 d on adult survival rate, parasitism, oviposition and offspring development, were measured and compared. [Results]  The survival rates of adults were 97.35% and 82.07% after 30 and 45 d cold storage, respectively. Survival declined with longer periods of cold storage to a minimum of 46.77% after 75 days. There was no significant difference in the number of hosts（Galleria mellonella Linnaeus）killed by, or the average mortality rate (79.00%-92.00%) of, female wasps that had been subject to 30-75 d cold storage compared to the control group (99.00%). However, cold storage significantly reduced the parasitism rate which was 25.00% after 30 days cold storage compared to 44.00% for the control. Cold storage increased the oviposition rate; the highest total number of eggs laid (78.60) was recorded after 30 d cold storage, followed by 60 d and 45 d (71.33 and 70.00, respectively), all of which were significantly higher than the control (47.80). Cold storage in did not affect hatching, pupation or adult emergence of progeny, but did decrease the ♀︰♂ sex ratio of offspring. [Conclusion]  Storing B. adoxophyesi at 10 ℃ for 30-60 d had no effect on the host paralysis rate, and increased the oviposition rate relative to the control. B. adoxophyesi should be kept in cold storage for no more than 60 d.
