刺回鱼寄生有S.实蝇幼虫比未被寄生的个体更快地从令人恐惧的头顶刺激中恢复。被寄生的鱼经常在刺激之后进食，而非被寄生的鱼则没有。从刺激的恢复时间是显着负相关的寄生负载，表明逐步削减的恐惧反应。中间宿主的抗捕食行为的改变可能取决于寄生虫的代谢需求，并且可能对寄生虫具有适应价值。
Sticklebacks parasitized by S. solidus larvae recover more quickly from a frightening overhead stimulus than non-parasitized individuals. Parasitized fish often feed subsequent to the stimulus, non-parasitized fish do not. Recovery time from the stimulus is significantly negatively correlated with parasitic load, indicating a progressive curtailment of the fright reaction. Modification of the anti-predator behavior of the intermediate host may depend on the metabolic demands of the parasite and potentially may be of adaptive value for the parasite.
