Timing of extreme heat events matters: exposure during parasitism disrupts top-down control

## Pardikes et al. Timing of extreme heat events matters: exposure during parasitism disrupts top-down control Data and analysis scripts for the manuscript Pardikes et al. 2025 *Timing of extreme heat events matters: exposure during parasitism disrupts top-down control*. Using these data and scripts, we investigated how the timing of extreme heat exposure impacts the outcome of host-parasitoid interactions. We measured the outcomes of 9 combinations of Drosophila-parasitoid interactions across four heat exposure timings: no heat exposure, heat exposure before an interaction, heat exposure during an interaction, and heat exposure after the interaction. We used 50 *Drosophila* eggs per vial; the vials served as replicates. We also measured the outcome of control vials unexposed to parasitoids. We analyzed the proportion of Drosophila survival, parasitism success, development times, and adult survival for wasps and Drosophila using generalized linear models.
