在确认工蜂（蜜蜂）从觅食恢复到育雏护理后，我们确定保幼激素（JH）是否介导这种形式的可塑性在行为发育和工人的年龄和基因型是否影响其表达的概率。JH滴度的测量支持这一假设，即蜜蜂行为发育的可塑性是JH由外在因素调制的结果。在由两个表型可区分的亚科组成的群体中，观察单独标记的蜜蜂发现，经历行为逆转的可能性受工人年龄的影响，但不受工人基因型的影响。工人的年龄逆转的影响是一致的，与以前制定的模型，年龄polyethism在蜜蜂的监管，预测不同年龄的工人有不同的反应阈值的任务相关的刺激。与其他形式的行为可塑性的结果相反，缺乏基因型对修正的影响。
After confirming that worker honey bees (Apis melifera) an revert from foraging to brood care, we determined whether juvenile hormone (JH) mediates this form of plasticity in behavioral development and whether worker age and genotype influence the probability of its expression. Measurement of JH titers support the hypothesis that plasticity in honey bee behavioral development is a consequence of modulation of JH by extrinsic factors. Observations of individually marked bees in a colony composed of two phenotypically distinguishable subfamilies revealed that the likelihood of undergoing behavioral reversion was influenced by worker age but not by worker genotype. The effect of worker age on reversion is consistent with a previously formulated model for the regulation of age polyethism in honey bees that predicts that workers of different ages have different response thresholds for task-associated stimuli. The lack of a genotypic effect on revision is in contrast to results for other forms of behavioral plasticity.
