母体效应是一种用于提高后代质量的进化策略。在蜜蜂（Apis mellifera）的母体效应的一个例子中，蜂王在蜂王细胞中产生的卵比在工蜂细胞中产生的卵更大，以便繁殖更好的女儿蜂王。本研究对蜂王室（QE）、工蜂室（WE）和工蜂室（2L）饲养的2日龄幼虫的形态指标、生殖组织和产卵能力进行了评价。此外，还对子代蜂王的形态指标和子代工蜂的工作性能进行了测定。QE组的胸重、卵巢管数、卵长、产蛋数和带帽窝数均显著高于WE组和2L组，表明QE组的繁殖能力优于其他组。此外，从QE后代蜂王有较大的胸部重量和大小比其他两个组。QE工蜂的后代也比其他两组工蜂具有更大的体型和更高的花粉采集和皇家的生产能力。这些结果表明，蜜蜂显示出深刻的母性影响女王的质量，可以跨代传递。这些发现为提高蜂王质量提供了依据，并对养蜂和农业生产具有一定的指导意义。
Maternal effects are an evolutionary strategy used to improve offspring quality. In an example of maternal effects in honey bees (Apis mellifera), mother queens produce larger eggs in queen cells than in worker cells in order to breed better daughter queens. In our current study, morphological indexes, reproductive tissues, and the egg-laying ability of newly reared queens reared with eggs laid in queen cells (QE), eggs laid in worker cells (WE), and 2-day-old larvae in worker cells (2L) were evaluated. In addition, morphological indexes of offspring queens and working performance of offspring workers were examined. The thorax weight, number of ovarioles, egg length, and number of laid eggs and capped broods of QE were significantly higher than those of WE and 2L, indicating that the reproductive capacity of QE group was better than that of other groups. Furthermore, offspring queens from QE had larger thorax weights and sizes than those from the other two groups. Offspring worker bees from QE also had larger body sizes and greater pollen-collecting and royal jelly-producing abilities than those of other two groups. These results demonstrate that honey bees display profound maternal effects on queen quality that can be transmitted across generations. These findings provide a basis for improving queen quality, with implications in apicultural and agricultural production.
