Comparative analysis of metabolome expression patterns in D. suzukii under different stresses. ( a ) PCA and ( b ) correlation plots between experimental groups with altered metabolites in (i) positive (ESI+) and (ii) negative ion mode (ESI−). Each colored dot indicates the number of repetitions ( n  = 3).
