寄生虫驱动的共同进化导致宿主发展出一种复杂且可能昂贵的防御机制，主要由免疫系统组成。尽管有证据表明免疫功能和生活史特征之间存在权衡，但使用和维持免疫功能的成本如何支付仍不清楚。我们测试了免疫攻击对白色甘蓝粉蝶（Pieris brassicae L.）滞育蛹与对照组相比，使用尼龙植入物挑战的个体的标准代谢率提高了近8%。因此，昆虫蛹免疫系统激活的成本可以用能量货币来表示。
Parasite-driven coevolution has led hosts to develop a complicated and potentially costly defence machinery, consisting mainly of the immune system. Despite the evidence for the trade-offs between immune function and life-history traits, it is still obscure how the costs of using and maintaining the immune function are paid. We tested whether immune challenge is energetically costly for white cabbage butterfly (Pieris brassicae L.) diapausing pupa. Individuals challenged with nylon implant raised their standard metabolic rate nearly 8% compared to the controls. Hence, costs of activation of immune system in insect pupa can be expressed in energetic currency.
