  1. APOP adult pre-oviposition period, TPOP total pre-oviposition period—both calculated using females that produced fertile eggs. Average oviposition days were calculated for days when the number of eggs laid was greater than zero. Standard errors were estimated using 100,000 bootstraps and compared using the paired bootstrap test based on the differences in confidence intervals. Means followed by different letters in the rows are significantly different (p < 0.05) by the paired bootstrap test
