最近的研究表明，巢内蜜蜂工人（意大利蜜蜂）之间的任务专业化模式的差异可以解释，在某种程度上，作为基因型变异的结果。在这里，我们提出的证据支持的假设，一个人的任务专业化的模式不仅受到她自己的基因型，但间接地，由她的巢友的基因型。在其各自亲株的菌落和另一株的菌落中观察到了来自两个蜜蜂品系的工蜂，其中一个被选择为高花粉囤积，另一个被选择为低花粉囤积。工蜂基因型和寄主群体类型影响其觅食活动。工人从高应变培养在低应变殖民地返回花粉的总觅食行程的75.6%，而工人从高应变培养在高应变殖民地返回花粉的总行程的53.5%。工人从低应变培养在低应变殖民地返回花粉的34.8%的总觅食行程，而工人从低应变培养在高应变殖民地返回花粉的总行程的2.6%。在第二个实验中也得到了类似的结果。我们认为，工人的影响，他们的巢友的行为间接通过他们对共享的殖民地环境的影响。工人从这些菌株的两种类型的殖民地环境的反应中看到的不对称性也表明，这些基因型表现出不同的反应规范。
Recent studies have shown that differences in patterns of task specialization among nestmate honey-bee workers (Apis mellifera) can be explained, in part, as a consequence of genotypic variability. Here, we present evidence supporting the hypothesis that an individual's pattern of task specialization is affected not only by her own genotype, but, indirectly, by the genotypes of her nestmates. Workers from two strains of honey bees, one selected for high pollen hoarding, the other for low pollen hoarding, were observed in colonies of their respective parent strains and in colonies of the other strain. Worker genotype and host-colony type affected foraging activity. Workers from the high strain fostered in low-strain colonies returned with pollen on 75.6% of total foraging trips, while workers from the high strain fostered in high-strain colonies returned with pollen on 53.5% of total trips. Workers from the low strain fostered in low-strain colonies returned with pollen on 34.8% of total foraging trips while workers from the low strain fostered in high-strain colonies returned with pollen on 2.6% of total trips. Similar results were obtained in a second experiment. We suggest that workers influence the behavior of their nestmates indirectly through their effects on the shared colony environment. The asymmetry seen in the response of workers from these strains to the two types of colony environments also suggests that these genotypes exhibit different norms of reaction.
