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

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 (Solanum tuberosum) and the Colorado potato beetle (CPB),
Leptinotarsa decemlineata (Coleoptera: Chrysomelidae), in the presence or
absence of their mutualistic microbial symbionts and another pest, the
potato aphid (Macrosiphum euphorbiae). Here we report changes in CPB
performance and leaf chemistry, specifically, volatile organic compounds
(VOCs) and glycoalkaloids content in host plants.
