Determining the ULT of species. The survival rate of each group is shown as a function of experimental temperature. Each dot represents the result for a group (n = 10 to 15 individuals). The curves are logistic dose–response fits. The intersection of the nonlinear regression line and the 50% threshold (horizontal dashed lines) corresponds to the ULT (indicated in gray type). Colors indicate feeding guild: phloem feeder (green), leaf miner (blue), and tissue piercer (orange). Species included spotted tentiform leaf miner, Phyllonorycter blancardella; rosy apple aphid, Dysaphis plantaginea; green apple aphid, Aphis pomi; pear lace bug, Stephanitis piri; brown mite, Bryobia rubrioculus; and two-spotted spider mite, Tetranychus urticae.
