Abstract BACKGROUND Silicon (Si) fertilization has been well‐documented to enhance plant resistance against insect pests by increasing the abrasiveness and toughness of leaf tissues. Additionally, Si also interacts with jasmonic acid pathway, which modulates antiherbivore induced defenses, including emission herbivore‐induced volatiles (HIPVs) that attract natural enemies. In this study, we examined influence on attractiveness nocturnal HIPVs from maize plants infested fall armyworm (FAW), Spodoptera frugiperda (JE Smith), predatory earwig Doru luteipes (Scudder). RESULTS laboratory assays, found did not alter constitutive predator D . However, upon infestation FAW larvae, Si‐fertilized emitted a volatile blend was more attractive D. Although composition non‐fertilized similar, terpene neryl acetate exclusively detected in HIPV plants. Tests synthetic demonstrated alone at specific concentration CONCLUSION This study demonstrates primes indirect defenses specifically amount blend, is responsible for enhanced earwig. Thus, can act as priming agent potentially recruitment once are FAW, thereby contributing suppress pest populations. © 2025 The Author(s).
