Table 1. Host species thermal tolerance upper limit (CT_max) and thermal performances: Optimal temperature (T_opt) and thermal breadth (T_breath defined here as the range where performance is above 80% of optimal) for overall species fitness (product of fecundity, developmental success and developmental speed) and fecundity measured as egg-laying capacity ± SD.

Data are from [51].
