The evolutionary biology of host-parasite relationships are considered here using a simple game-theory model in which hosts play against parasite and vice versa. In this model, the players can choose between two strategies (aggressive or not aggressive) and the utility of the game is envisaged in terms of fitness and selective costs. The game solutions suggest that the two types of confrontation are encountered in symbiotic relationships and thus constitute two Evolutionary Stable Strategies (ESS). These observations lead us to discuss: (i) the status of different kinds of symbiotic relationships (i.e. parasitoidism; parasitism, commensalism and mutualism) related to selective costs and (ii) the position of coevolution in this game theory context.
本文运用一个简单的博弈论模型来探讨宿主与寄生虫关系的进化生物学，在该模型中宿主与寄生虫相互对抗。在这个模型中，参与者可以在两种策略（攻击性或非攻击性）之间进行选择，并且博弈的效用是根据适应性和选择成本来设想的。博弈解决方案表明，在共生关系中会出现两种对抗类型，因此构成了两种进化稳定策略（ESS）。这些观察结果促使我们讨论：（i）与选择成本相关的不同种类共生关系（即拟寄生、寄生、共栖和互利共生）的状态；（ii）在这种博弈论背景下协同进化的地位。
