Schematic drawing of the experimental procedure for testing D. suzukii oviposition avoidance of egg-laying sites previously exposed to D. melanogaster. Details of each experiment, among which origin, sex, and numbers of D. suzukii and D. melanogaster flies, cage size, and oviposition substrate, are described in Table S2 of the Materials and methods. Note a male D. suzukii is depicted in the plastic cage as only males harbor the spotted wings that give the species its vernacular name, the Spotted-Wing Drosophila
