Effect of the vector composition on the density of Drosophila suzukii (A) and Drosophila melanogaster (B) under different temperatures. The upper, middle, and lower lines associated with the boxes show the 75th, 50th, and 25th percentiles of the data, respectively. Single: A single-species vector, D. suzukii (A) or D. melanogaster (B) infecting the grapes (the single-vector treatment). Combined: the two Drosophila species (D. suzukii and D. melanogaster) infecting the grapes together (the combined-vector treatment). The combined-vector treatment data (‘Combined’ in the graph, initially 10 pairs of D. suzukii and 10 pairs of D. melanogaster combined) were compared directly, whereas the data used for comparison of the single-vector treatment (‘Single’ in the graph) were the half of the values recorded for each trait (just like initially 10 pairs of D. suzukii (A) or 10 pairs of D. melanogaster (B)) in each replicate (see details in the Statistical analysis section). Healthy, Wounded, and Wounded + Bacteria: the initial health conditions of the grapes. Bacteria: Gluconobacter oxydans and Acetobacter acetic coinoculation
