最近的工作表明，果蝇对寄生蜂Asobara tabida攻击的抗性进化受到与幼虫竞争能力的权衡。然而，有两个非常重要的问题需要回答。首先，这是一个普遍的成本，还是寄生蜂特有的？其次，对一种寄生蜂物种的免疫反应的选择性增加是否会导致对其他寄生蜂物种的抵抗力的相关变化？这两个问题的答案将影响这些物种的共同进化动态，也可能对群落结构产生以前未被考虑但却很重要的影响。
Recent work has shown that the evolution of Drosophila melanogaster resistance to attack by the parasitoid Asobara tabida is constrained by a trade-off with larval competitive ability. However, there are two very important questions that need to be answered. First, is this a general cost, or is it parasitoid specific? Second, does a selected increase in immune response against one parasitoid species result in a correlated change in resistance to other parasitoid species? The answers to both questions will influence the coevolutionary dynamics of these species, and also may have a previously unconsidered, yet important, influence on community structure.
