  1. OTU richness and diversity values were calculated at genus-level. aAn unpaired two-tailed t-test was performed to assess the significance of differences between groups unless otherwise stated. *P < 0.05; **P < 0.001; ***P < 0.0001. Control group: larvae fed on artificial diet; Treatment group: larvae fed on artificial diet with 1% EGCG supplement.
