Article Abstract

Plants employ both direct and indirect defense mechanisms to combat herbivorous insects, with volatile emissions playing a critical role in attracting natural enemies of pests. This study investigates the effects of Atailing, a plant immunity inducer, on rice () defenses against the striped stem borer (, SSB). Behavioral assays revealed that Atailing-treated rice plants significantly enhanced (the major egg parasitoid of ) attraction, increasing oviposition parasitism rates (direct, 94.7%; indirect, 131.1%), confirming indirect defense as an active strategy induced by Atailing. GC-MS analysis identified six key functional compounds that significantly attract . Chemical and biological assays demonstrated that the concentrations of salicylic acid (SA) and trypsin inhibitors (TrypPIs) were significantly increased by 30.1% and 13.2%, respectively. These findings highlight the potential of Atailing in modulating volatile emissions to attract natural enemies and provide evidence of its potential as a sustainable pest management tool.

Effect of brand love on brand defense mediated by customer brand engagement: The moderated mediation role of regulatory focus.

In an era where negative word-of-mouth escalates and spreads rapidly on social media, understanding the psychological mechanisms of brand defense is of critical importance. Expanding on literature that establishes brand love as a strong predictor of pro-brand behaviors in offline settings, this study investigates the psychological process that transforms this emotion into defensive behaviors in the high-visibility and high-risk environment of social media. This study advances and tests a moderated mediation model, specifying that customer brand engagement (CBE) mediates the brand love-brand defense relationship.

Extrafloral nectaries (EFNs) are specialized plant glands that secrete nectar but are not related to pollination. Several ants feed on EFNs and, in exchange, they often attack herbivores, reducing the consumption of leaf tissue and floral parts, and enhancing plant performance. Although most empirical studies and reviews have demonstrated that ant visitation benefits EFN-bearing plants, many others have failed to show ants as protective partners.
