摘要
蜜蜂是典型的模式昆虫,也是重要的经济昆虫,温度对其发育有着重要的影响。本文研究了低温20℃处理不同时长对意大利蜜蜂Apis mellifera ligustica 0-66 h受精卵的影响。结果表明:低温处理导致意大利蜜蜂受精卵的孵化率下降,发育历期显著延长。低温对蜜蜂受精卵孵化率影响程度与卵龄关系较大。0-9 h卵龄对低温敏感,其次是12-24 h卵龄,36 h以上卵龄后则较耐低温。0-66 h的卵受低温影响后发育历期延长平均值与低温胁迫时间呈显著的线性正相关。低温对蜜蜂卵发育有影响,在蜜蜂饲养管理的早春增长阶段,需要加强蜂群的保温。
Honeybee is a typical model as well as the keynote economic insect. Temperature is crucial to embryonic development of the Italian honeybees Apis mellifera ligustica. In the present paper we studied on low temperature effects at 20 °C for different time on the 0 - 66 h fertilized egg. The results showed that the hatchability decreased and the development durations were prolonged in stressed fertilized eggs. Fertilized eggs of 0 - 9 h were most susceptible to cold temperature, followed by eggs of 12 -24 h and 〉36 h, suggesting that the late stage of embryos had a less susceptibility to cold temperatures. The average prolonged development duration was positively linearly correlated to the stress time under low temperature. Our data suggested that strategies should be taken to prevent brood rearing hives from cold exposure during early spring management.
