The lowercase letters in the same row indicate significant differences in mortality at different developmental stages of A. custos on different temperature (P<0.05). A paired bootstrap test was used to detect statistical differences in the mortality at different stages of A. custos on different the temperatures. Standard errors were estimated from 100,000 bootstrap resampling. N represents the number of viable eggs and test insects
