Data from: Effects of a heat wave event on the chemical ecology of species interactions in the potato agroecosystem

<p>Heat waves, brief periods of unusually high temperatures, are increasing in frequency and intensity globally. Such extreme weather events can alter plant chemistry, disrupting species interactions that contribute to pest suppression or increase their performance. Yet, most heat wave studies focus on pairwise interactions, leaving us with a poor understanding of how complex agroecosystems respond to temperature extremes. We addressed this knowledge gap by simulating an experimental heat wave in the field on potato plants (<em>Solanum tuberosum</em>) and the Colorado potato beetle (CPB), <em>Leptinotarsa decemlineata</em> (Coleoptera: Chrysomelidae), in the presence or absence of their mutualistic microbial symbionts and another pest, the potato aphid (<em>Macrosiphum euphorbiae</em>). Here we report changes in CPB performance and leaf chemistry, specifically, volatile organic compounds (VOCs) and glycoalkaloids content in host plants.</p>
