BEO–βCD\\\/GA showed greater toxicity than BEO, producing lower LC values and higher T. castaneum mortality across concentrations and exposure periods. The carrier substances showed no toxicity to T. castaneum, confirming that the observed effects were due to BEO or BEO–βCD\\\/GA. The LC50 and LC90 values of BEO–βCD\\\/GA were consistently lower than those of BEO across all exposure periods (1–7 days). At 7 days, BEO–βCD\\\/GA recorded markedly lower LC50 (106.85 ppm; 3.15–173.54) and LC90 (319.49 ppm; 200.18–4468.97) compared with BEO (LC50: 437.72 ppm: 359.29–596.06; LC90: 3195.87 ppm: 1710.83–10801.66). The BEO–βCD\\\/GA achieved near-complete inhibition of progeny emergence (97–100%) at higher concentrations, compared to 61–79% for BEO. In addition, BEO–βCD\\\/GA significantly reduced grain weight loss and exhibited strong antifeedant activity. Neither treatment adversely affected wheat germination nor seedling vigor. These physicochemical characteristics, together with the formulation’s enhanced insecticidal performance, suggest improved stability and bioavailability of BEO within the βCD\\\/GA system, making it a promising, eco-friendly alternative for sustainable stored-product pest management.\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/futurenews24.com\\\/index.php\\\/2026\\\/07\\\/17\\\/s41598-026-61299-8\\\/#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/futurenews24.com\\\/index.php\\\/2026\\\/07\\\/17\\\/s41598-026-61299-8\\\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"en-US\",\"@id\":\"https:\\\/\\\/futurenews24.com\\\/index.php\\\/2026\\\/07\\\/17\\\/s41598-026-61299-8\\\/#primaryimage\",\"url\":\"https:\\\/\\\/media.springernature.com\\\/m685\\\/springer-static\\\/image\\\/art%3A10.1038%2Fs41598-026-61299-8\\\/MediaObjects\\\/41598_2026_61299_Fig1_HTML.png\",\"contentUrl\":\"https:\\\/\\\/media.springernature.com\\\/m685\\\/springer-static\\\/image\\\/art%3A10.1038%2Fs41598-026-61299-8\\\/MediaObjects\\\/41598_2026_61299_Fig1_HTML.png\"},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/futurenews24.com\\\/index.php\\\/2026\\\/07\\\/17\\\/s41598-026-61299-8\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/futurenews24.com\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Enhanced insecticidal efficacy of nanoencapsulated bergamot important oil towards stored-product pest Tribolium castaneum (Herbst)\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/futurenews24.com\\\/#website\",\"url\":\"https:\\\/\\\/futurenews24.com\\\/\",\"name\":\"Future News 24\",\"description\":\"The Smart Hub for AI and Next-Gen Innovation\",\"publisher\":{\"@id\":\"https:\\\/\\\/futurenews24.com\\\/#organization\"},\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":{\"@type\":\"EntryPoint\",\"urlTemplate\":\"https:\\\/\\\/futurenews24.com\\\/?s={search_term_string}\"},\"query-input\":{\"@type\":\"PropertyValueSpecification\",\"valueRequired\":true,\"valueName\":\"search_term_string\"}}],\"inLanguage\":\"en-US\"},{\"@type\":\"Organization\",\"@id\":\"https:\\\/\\\/futurenews24.com\\\/#organization\",\"name\":\"Future News 24\",\"url\":\"https:\\\/\\\/futurenews24.com\\\/\",\"logo\":{\"@type\":\"ImageObject\",\"inLanguage\":\"en-US\",\"@id\":\"https:\\\/\\\/futurenews24.com\\\/#\\\/schema\\\/logo\\\/image\\\/\",\"url\":\"https:\\\/\\\/futurenews24.com\\\/wp-content\\\/uploads\\\/2026\\\/06\\\/fn24-favicon.png\",\"contentUrl\":\"https:\\\/\\\/futurenews24.com\\\/wp-content\\\/uploads\\\/2026\\\/06\\\/fn24-favicon.png\",\"width\":250,\"height\":250,\"caption\":\"Future News 24\"},\"image\":{\"@id\":\"https:\\\/\\\/futurenews24.com\\\/#\\\/schema\\\/logo\\\/image\\\/\"}},{\"@type\":\"Person\",\"@id\":\"https:\\\/\\\/futurenews24.com\\\/#\\\/schema\\\/person\\\/cecad1bde21cfc357cf70128144d6c83\",\"name\":\"Future News 24\",\"image\":{\"@type\":\"ImageObject\",\"inLanguage\":\"en-US\",\"@id\":\"https:\\\/\\\/secure.gravatar.com\\\/avatar\\\/d57f07142d73cb5503ab2446ea7bc9ef3d0a5ba378d64a6157692311e42bf097?s=96&d=mm&r=g\",\"url\":\"https:\\\/\\\/secure.gravatar.com\\\/avatar\\\/d57f07142d73cb5503ab2446ea7bc9ef3d0a5ba378d64a6157692311e42bf097?s=96&d=mm&r=g\",\"contentUrl\":\"https:\\\/\\\/secure.gravatar.com\\\/avatar\\\/d57f07142d73cb5503ab2446ea7bc9ef3d0a5ba378d64a6157692311e42bf097?s=96&d=mm&r=g\",\"caption\":\"Future News 24\"},\"sameAs\":[\"https:\\\/\\\/futurenews24.com\"],\"url\":\"https:\\\/\\\/futurenews24.com\\\/index.php\\\/author\\\/mridulpahuja20\\\/\"}]}<\/script>\n<!-- \/ Yoast SEO plugin. -->","yoast_head_json":{"title":"Enhanced insecticidal efficacy of nanoencapsulated bergamot important oil towards stored-product pest Tribolium castaneum (Herbst) - Future News 24","description":"In this study, bergamot essential oil (BEO) was encapsulated within β-cyclodextrin\/gum Arabic (BEO–βCD\/GA) to enhance its physicochemical properties and its toxicity against Tribolium castaneum, a major stored-product pest.
