Figure 2.

Drosophila suzukii adult survival (average and CI from n = 3 samples) in tubes treated with Photorhabdus luminescens (10⁶ cells mL⁻¹) or P. luminescens culture supernatant over 9 days after application (DAA). Survival rates were compared to 10 mM MgSO₄ (control) or axenic Luria–Bertani (LB) medium. Different letters show significant differences among different treatments for each day, according to LSD test; p < 0.05.
