Abstract BACKGROUND Drosophila suzukii is an invasive pest causing high losses of agricultural crops. Conventional treatment strategies are considered problematic for their risk inducing resistance and environmental harm. Photodynamic Inactivation (PDI) based on the photosensitizer‐mediated light‐dependent generation reactive oxygen species. Natural food‐grade photosensitizers, such as food additive sodium magnesium chlorophyllin (Chl, E140), have been proven effective against microbial pathogens several pests. The aim this study to assess whether principle Chl‐based PDI D. could be transferred from laboratory towards practical conditions. RESULTS We prove that photokilled after feeding 5 mM Chl with 3% sucrose (98.4% median moribundity, 9 h drug light interval, 78.9 J/cm 2 radiant exposure). Therefore, aspects safety feasibility were assessed, using streamlined variations same assay: required photosensitizer concentration reduced 0.5 (90.1% moribundity 6 days 315.6 illumination LEDs). was photoactivable sunlight (92.5% 294.5 1 Chl). Offering alternative lures did not impair effect. Photobleaching rendered non‐toxic (2.5% bleaching subsequent 157.8 ). Furthermore, fluorescence microscopy Chl‐fed flies confirmed accumulation in flies' intestines. CONCLUSION Our findings demonstrate harnessed a safe management © 2025 Author(s).
