当植物和食草动物对变化的物候线索（如温度或融雪日期）有不同的反应时，就会发生物候不匹配。这通常会将食草动物的喂养转移到质量较低的植物阶段。草食动物对植物品质的反应也可能由温度介导，这可能导致温度-物候相互作用。我们研究了温度和寄主植物物候对蚜虫丰度和与蚂蚁的共生关系的影响。在这个研究系统中，蚜虫寄生在寄主植物川芎（Ligusticum porteri）的开花茎上。像其他蚜虫一样，这种蚜虫的丰富程度依赖于蚂蚁的保护。为了了解寄主植物物候和温度对蚜虫丰度的影响，我们采用了多年的观测研究和田间试验。在2017-2021年的5年时间里，我们观察了20个寄主植物种群，跟踪了温度和融雪日期，以及寄主植物物候和昆虫丰度。我们发现寄主植物和蚜虫物候对温度和融雪时间有不同的响应。早期融雪对寄主植物物候的加速程度大于蚜虫物候，而蚜虫物候对温度的响应更大。当蚜虫在开花后阶段定殖到寄主植物时，蚜虫群体建立和蚂蚁招募的可能性都降低了。2019年，我们通过实验加速了寄主植物物候，将融雪日期提前了两周。我们将这种处理与围绕蚜虫菌落的开放式顶部加热室结合起来。在环境温度下，当它们发生在开花阶段的寄主植物上时，菌落生长最快。总之，我们的研究结果表明，与寄主植物的物候不匹配会降低蚜虫的丰度，并且这种影响会随着温度的升高和蚜虫共生关系的变化而加剧。
Phenological mismatch can occur when plants and herbivores differentially respond to changing phenological cues, such as temperature or snow melt date. This often shifts herbivore feeding to plant stages of lower quality. How herbivores respond to plant quality may be also mediated by temperature, which could lead to temperature‐by‐phenology interactions. We examined how aphid abundance and mutualism with ants were impacted by temperature and host plant phenology. In this study system, aphidsAphis asclepiadiscolonize flowering stalks of the host plant,Ligusticum porteri. Like other aphids, abundance of this species is dependent on ant protection. To understand how host plant phenology and temperature affect aphid abundance, we used a multiyear observational study and a field experiment. We observed 20 host plant populations over five years (2017–2021), tracking temperature and snow melt date as well as host plant phenology and insect abundance. We found host plant and aphid phenology to differentially respond to temperature and snow melt timing. Early snow melt accelerated host plant phenology to a greater extent than aphid phenology, which was more responsive to temperature. Both the likelihood of aphid colony establishment and ant recruitment were reduced when aphids colonized host plants at post‐flowering stages. In 2019, we experimentally accelerated host plant phenology by advancing snow melt date by two weeks. We factorially combined this treatment with open top warming chambers surrounding aphid colonies. Greatest growth occurred for colonies under ambient temperatures when they occurred on host plants at the flowering stage. Altogether, our results suggest that phenological mismatch with host plants can decrease aphid abundance, and this effect is exacerbated by temperature increases and changes to the ant–aphid mutualism.
