在不同滞育条件下测量了总共 2210 只大黄蜂蜂王 (Bombus terrestris) 的滞育存活率和滞育后表现（即，如果蜂王开始产卵）：5 种温度（-5、0、5、10 和 15 摄氏度）以及 5 种暴露时间（1、2、4、6 和 8 个月）。结果显示，开始时的重量滞育在很大程度上决定了是否 蜂王能够在滞育中存活下来。滞育前湿重低于 0.6 克的蜂王无法存活，但对于超过此阈值的蜂王，较高的滞育前重量并不会提高其滞育后的性能。温度对滞育存活率没有影响； 76% 的生存差异可以用治疗持续时间来解释。温度和暴露时间对滞育后的表现均没有影响。还确定了产卵蜂王的产卵前期。产卵前期受温度和暴露时间的影响：产卵前期随着温度的降低而缩短，但也随着处理持续时间的增加而缩短。
Diapause survival and post-diapause performance (i.e., if a queen starts to lay eggs) of in total 2210 bumblebee queens (Bombus terrestris) were measured under different diapause regimes: 5 temperatures (-5, 0, 5, 10 and 15 degrees C) in combination with 5 durations of exposure (1, 2, 4, 6 and 8 months).The results show that weight at the start of diapause determines to a large extent whether a queen will be able to survive diapause. Queens with a wet weight below 0.6 g prior to diapause did not survive, but for those queens exceeding this threshold a higher pre-diapause weight did not increase their post-diapause performance.There was no effect of temperature on diapause survival; 76% of the variance in survival could be explained by the duration of the treatment. Neither temperature nor duration of exposure had an effect on post-diapause performance. The preoviposition period of the queens that laid eggs was also determined. The preoviposition period was affected by both temperature and duration of exposure: the preoviposition period decreased with decreasing temperature but also with increasing duration of the treatment.
