Steinernema carpocapsae exhibits temperature-induced olfactory plasticity. ac Temperature-swapping infective juveniles (IJs) from 25 °C to 15 °C, or vice versa, reversed their olfactory preferences. Olfactory plasticity occurred more rapidly in younger IJs (a) than older IJs (b, c). *** P < 0.001 relative to day 0 IJs; two-way ANOVA with Dunnett’s post-test; n = 6–22 trials for each condition. d The olfactory responses of IJs maintained at 25 °C remained relatively unchanged over a 70-day period, although the response to 1-hexanol at day 70 was slightly reduced. Day 28 data are taken from Fig. 2. * P < 0.05 relative to day 0 IJs; two-way ANOVA with Dunnett’s post-test; n = 6–22 trials for each condition. e Temperature-induced olfactory plasticity occurred gradually over the course of days; n = 6–22 trials for each time point. For all graphs, error bars represent standard error of the mean (SEM). Mean, n, and SEM values for each assay are listed in Additional file 7: Dataset S1
