This work aimed to compare the measurements, developmental length, and weight of eggs laid by colony queens naturally mated halfqueens and laying workers of the Egyptian honey bee Apis mellifera lamarckii. The dry weight of workers emerged from the queen and halfqueen eggs were also compared. The eggs of laying workers were significantly shorter, slimmer, and lighter than the eggs of the other two female castes. Egg length and egg width fluctuated significantly in the three female castes throughout the experimental period with different patterns of change. The developmental time of laying worker eggs was significantly shorter than that of queen and halfqueen. Eggs from all three castes change their sizes during the whole incubation period. No significant difference was found between the mean weight of newly emerged workers from the queen and halfqueen eggs. Three well-separated clusters, representing the eggs of the three castes, were obtained by using discriminant analysis. The results revealed that queens and halfqueens are closely related to each other.

拉马克蜜蜂蜂王、半蜂王和工蜂产卵与新兴工蜂体重比较

这项工作旨在比较埃及蜜蜂 Apis mellifera lamarckii 自然交配的半蜂后和产卵工蜂产下的卵的测量值、发育长度和重量。还比较了从皇后和半皇后卵中出现的工人的干重。与其他两个女性种姓相比,产蛋工人的卵明显更短、更细、更轻。在整个实验期间,三个女性种姓的卵长和卵宽波动显着,变化模式不同。工蛋的发育时间明显短于蜂王和半蜂王。在整个孵化期间,来自所有三个种姓的鸡蛋都会改变它们的大小。蜂王和半蜂王卵中新出现的工蚁的平均体重之间没有发现显着差异。通过使用判别分析获得三个分离良好的集群,代表三个种姓的鸡蛋。结果显示,皇后和半皇后彼此密切相关。
