研究了日本桃金娘（Myrmecina nipponica Wheeler）中翅/脱翅雌蜂（alate/dealate）和永久无翅雌蜂（intermorphic queen）的形态和发育可塑性。晚期/晚期蜂王和间型蜂王的繁殖能力几乎相等。未授精的雌蜂和未授精的雌蜂的卵巢数量几乎相同，但受精的异态雌蜂的卵巢数量明显多于未授精的雌蜂。为了确定M. nipponica的异态蜂后是“异态蜂后”还是“异态蜂后”，我们比较了每个女性种姓的七个外部特征。异态蜂后的外部特征，尤其是前额宽度和中胚层韦伯长度，与工蜂蜂相比，与异态蜂后更相似。关于卵巢的数据表明，互态蜂王的生殖能力类似于异态蜂王。没有可繁殖的雌性蜂群和低温刺激了新的异形蜂王的产生，但没有刺激新的异形蜂王的产生。互态蜂后的产生所带来的可塑性很可能是对食物资源匮乏和筑巢地点不均匀的适应。
We examined the morphology and developmental plasticity of alate/dealate queens and permanently wingless reproductive females (hereafter referred to as "intermorphic queens") in Myrmecina nipponica Wheeler. Alate/dealate queens and intermorphic queens had nearly equal reproductive capacities. The number of ovarioles was almost identical between virgin and inseminated alate/dealate queens, but inseminated intermorphic queens had significantly more ovarioles than virgin females. To determine if intermorphic queens in M. nipponica are 'ergatoid queens' or 'intercaste,' we compared seven external traits of each female caste. The external traits of intermorphic queens, in particular pronotal width and Weber's length of the mesosoma, were more similar to workers than to alate/dealate queens. Data on ovarioles suggest that the intermorphic queens have a reproductive ability similar to alate/dealate queens. The absence of a reproductive female in a colony and low temperature stimulated the production of new intermorphic queens but not new alate queens. The plasticity afforded by the production of intermorphic queens is likely an adaptation to low food resources and patchy nest sites.
