Abstract BACKGROUND Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici , is a foliar disease affecting wheat crops against which conventional control methods are not totally effective. During inter‐epidemic periods the fungus survives in wheat residues left on the ground. In this study, we tested the potential of the collembolan Heteromurus nitidus – a springtail species present in field soils and known to interact with different fungal species – as a potential bioregulation agent of Z. tritici on wheat residues through a choice and consumption experiment. RESULTS Springtails preferred inoculated fresh residues but did not have a preference between inoculated and uninoculated old residues. Springtails grazed on Z. tritici fruiting bodies and reduced pycnidiospore numbers by ten‐fold compared to control inoculated fresh residues. Attraction toward fresh inoculated residues and pycnidiospore reduction support the hypothesis that Z. tritici is a food source for springtails. Heteromurus nitidus showed no preference between inoculated and uninoculated 18‐month‐old residues, probably because they no longer produced ascospores. CONCLUSION Attraction towards fresh residues and spore reduction support our hypothesis that H. nitidus may contribute to the bioregulation of Z. tritici . Perspectives for field application would be determined by the ability of H. nitidus and Z. tritici to interact at key epidemiological stages. The impact of H. nitidus on the quantity of pathogen primary inoculum over time should be estimated using residues of intermediate age. This would help to identify the optimal period for enhancing the effectiveness of springtails as consumers of Z. tritici . © 2024 The Authors.
