Metabolomics of silkworm larvae reared on fresh mulberry leaves or the artificial diet. (a) Partial least squares-discriminant analysis (PLS-DA). (b) Classification of metabolites and (c) the heat map. Data from the PLS-DA were analyzed using SIMCA-P 13.0 software (Umetrics AB, Umeå, Sweden). The x-axis shows the names of the metabolites, and the y-axis shows the names of the samples (strain-food-sex). Hi and Lo indicate silkworm strains that exhibited high or low ingestion of the artificial diet, respectively. M, fresh mulberry leaves, n = 8 replicates; A, artificial diet, n = 7 replicates; ♂, male; ♀, female. Each sample comprised five larvae, which provided an equal volume of hemolymph.
