通过温度变化实验，探讨了热带双环蝶个体发育可塑性的适应意义。与之前关于成虫适应的研究结果相反，我们没有发现任何支持适应性发育可塑性的证据，因为当幼虫的饲养温度与蛹前或蛹发育期间的温度相匹配时，成虫的存活率并没有提高。极端温度大大降低了存活率，支持了“最佳发育温度”假说。在27°C的较高饲养温度下，蜕变效率更高，卵孵化成功率也更高，这表明20°C的较低温度对这种热带蝴蝶来说已经有点压力了。
We explored the adaptive significance of developmental plasticity in the tropical butterfly Bicyclus anynana using two experiments including temperature changes during ontogeny. In contrast to previous findings on adult acclimation, we could not find any evidence in support of adaptive developmental plasticity, as survival until adulthood was not enhanced when larval rearing temperatures matched the temperatures experienced during prepupal or pupal development. Extreme temperatures substantially reduced survival, supporting the ‘optimal developmental temperature’ hypothesis. Metamorphosis was more efficient at the higher rearing temperature of 27°C, where egg hatching success was also higher, indicating that the lower temperature of 20°C is already slightly stressful for this tropical butterfly.
