X-ray irradiation and modified atmospheres (MAs) provide eco-friendly, chemical-free methods for pest management. Although a low-oxygen atmospheric treatment improves the performance of some irradiated insects, its influence on quarantine insects impacts control efficacy have yet to be investigated. Based bioassay results, this study employed direct immersion solid-phase microextraction (DI-SPME) combined with gas chromatography-mass spectrometry (GC-MS) determine metabolic profiles late third-instar B. dorsalis larvae under normoxia (CON, Air), hypoxia (95% N2 + 5% O2, HY), super-hypoxia (99.5% 0.5% Sup-HY), irradiation-alone (116 Gy, IR-alone), (HY IR) (Sup-HY IR). Our findings reveal that, compared IR-alone group, IR HY Sup-HY increases larval pupation dorsalis, weakens delaying effect developmental stage. However, these 3 groups further hinder adult emergence phytosanitary dose 116 Gy. Moreover, all IR-treated groups, including IR-alone, IR, lead insect death as coarctate or pupae. Pathway analysis identified changed pathways across groups. Specifically, changes in lipid metabolism-related were observed: vs. CON, 2 5 each CON. The treatments induce comparable modifications pathways. demonstrate significantly fewer changes. research suggests that environment Sup-HY) might enhance radiation tolerance by stabilizing metabolism at biologically feasible levels. Additionally, our indicate current contributes effective management without being influenced radioprotective effects. These results hold significant importance understanding biological effects developing IR-specific regulatory guidelines MA environments.
