Abbreviations: PP pupae production, MPP male pupae production, M% percentage of male pupae in PP
aLarval survival was calculated as: (Total number of pupae collected + Residual number of larvae after sex separation) / (Estimated number of larvae per tray)
Note: Within each column, values followed by different lowercase or capital letters were statistically different using ANOVA analysis and Tukey post-hoc test (P < 0.05)
