摘　　要：目的观察成虫期冷藏对丽蝇蛹集金小蜂雌蜂寿命和繁殖能力的影响。方法考察羽化后不同时间的丽蝇蛹集金小蜂雌蜂在15℃冷藏不同时间后的寿命、寄生和繁殖能力。结果成虫期冷藏可延长丽蝇蛹集金小蜂雌蜂的成虫寿命,但随冷藏时间的延长,丽蝇蛹集金小蜂雌蜂的寄生能力和产卵能力均受到不同程度的负面影响,当冷藏时间不超过12d时,丽蝇蛹集金小蜂雌蜂的寄生和产卵能力均不受显著影响,而超过12d后,其产卵和寄生能力均呈线性下降趋势;冷藏前至冷藏后24d,雌蜂对棕尾别麻蝇蛹的寄生率由85%下降至35%,蝇蛹的平均出蜂数由33头/蛹下降至6头/蛹,而后代的雌蜂比和体长均不受影响。结论成虫期冷藏可延长丽蝇蛹集金小蜂雌蜂的寿命,但影响其繁殖能力。Objective To observe the effect of adult cold storage on the longevity and reproductive capacity of female Nasonia vitripennis. Methods The female N. vitripennis emerged on different days were cold stored at 15 ℃ for different period. Their longevity, parasitic capacity and reproductive capacity were then measured. Results The longevity of female N. vitripennis was extended after cold storage at adult stage. However, as the cold storage time prolonged, the parasitic and reproductive capacities were compromised. At a cold storage time for less than 12 d, the impact on these capacities of female N. vitripennis was not remarkable. In contrast, after cold storage of over 12 d, the egg production and parasitic capacities declined linearly. After cold stored for 24 d, the parasitic ratio of Boettcherisca peregrina by N. vitripennis reduced to 35% from 85% before cold storage and the average emerging parasitoid progeny to 6 from 33 per fly pupa. However, the female adult rate and the body length of the progeny were not affected. Conclusion Adult cold storage extends the longevity of female N. vitripennis at the cost of reproductive capability.
