Insect Sci."],"abstract":"\n Introduction<\/jats:title>\n \n This study developed an eco-friendly attractant from fermented fruit waste juices for\n Drosophila melanogaster<\/jats:italic>\n (Diptera: Drosophilidae), a model dipteran species, aligning with Sustainable Development Goals (SDGs) SDG 2 (Zero Hunger), 12 (Responsible Consumption and Production) and 15 (Life on Land) through sustainable waste valorization and reduced reliance on synthetic pesticides.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n Multi-choice bioassays were conducted to evaluate the attraction of\n D. melanogaster<\/jats:italic>\n to fruit waste juices subjected to different fermentation durations. The microorganisms present in the most effective fermented banana juice were identified using morphological and molecular approaches. Gas chromatography\u2013mass spectrometry (GC\u2013MS) was used to characterize the volatile organic compound (VOC) profiles of fresh and fermented juices. To develop a greenhouse-deployable formulation, sodium alginate\u2013carboxymethyl cellulose (CMC) beads loaded with fresh and fermented banana juice were evaluated under greenhouse conditions. Molecular docking analysis was performed against the odorant-binding protein dmelOBP28a (PDB ID: 6QQ4) to assess the predicted binding interactions of selected VOCs with the target protein.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Fermentation duration significantly enhanced insect attraction across all tested substrates, with banana juice (\n Musa acuminata<\/jats:italic>\n ) fermented for seven days eliciting the highest attraction rate (34.07%; F\n (5,12)<\/jats:sub>\n = 121.331; p &lt; 0.001). The microorganisms present in the more effective fermented banana juice were identified as\n Saccharomyces cerevisiae<\/jats:italic>\n (PX986379.1),\n Lactiplantibacillus<\/jats:italic>\n plantarum (PX986372.1), and\n Acetobacter aceti<\/jats:italic>\n (PX986373.1). GC\u2013MS analysis showed that fermentation substantially diversified the VOC profile, yielding elevated levels of D-limonene, phenolic derivatives, esters, and organic acids that correlated with increased attraction. Under greenhouse conditions, sodium alginate\u2013CMC beads loaded with seven-day fermented juice achieved a higher attraction rate (82.96%; F(2,6) = 358.183; p &lt; 0.001) than those loaded with fresh juice, confirming the effectiveness of the controlled-release delivery system. Molecular docking analysis indicated that 2-Propenoic acid, 6-methylheptyl ester and D-limonene exhibited the strongest predicted binding affinities to dmelOBP28a, with docking scores of \u22126.7 and \u22126.5 kcal\/mol, respectively.\n <\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n \n These findings demonstrate that fermented fruit waste, particularly banana waste, can be developed into an affordable and environmentally friendly fruit fly attractant by combining microbial fermentation, chemical ecology, and controlled-release formulation techniques. The favorable predicted interactions of 2-Propenoic acid, 6-methylheptyl ester and D-limonene with dmelOBP28a suggest that these compounds may contribute to odor-mediated attraction in\n D. melanogaster<\/jats:italic>\n . However, the present study did not directly evaluate reductions in fruit infestation or postharvest fruit losses. Further field and postharvest studies are therefore needed to determine the potential of this approach for reducing fruit damage and associated losses.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/finsc.2026.1933666","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T05:45:51Z","timestamp":1790574351000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Fermented fruit waste extract-loaded sodium alginate beads for the sustainable management of Drosophila melanogaster (Diptera: Drosophilidae)"],"prefix":"10.3389","volume":"6","author":[{"given":"Kannan","family":"Swathy","sequence":"first","affiliation":[{"name":"Department of Entomology and Plant Pathology, Faculty of Agriculture, Chiang Mai University","place":["Chiang Mai, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Perumal","family":"Vivekanandhan","sequence":"additional","affiliation":[{"name":"Department of Entomology and Plant Pathology, Faculty of Agriculture, Chiang Mai University","place":["Chiang Mai, Thailand"]},{"name":"Office of Research Administration, Chiang Mai University","place":["Chiang Mai, Thailand"]},{"name":"Center of Omics for High-Value Agriculture, Faculty of Agriculture, Chiang Mai University","place":["Chiang Mai, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patcharin","family":"Krutmuang","sequence":"additional","affiliation":[{"name":"Department of Entomology and Plant Pathology, Faculty of Agriculture, Chiang Mai University","place":["Chiang Mai, Thailand"]},{"name":"Center of Omics for High-Value Agriculture, Faculty of Agriculture, Chiang Mai University","place":["Chiang Mai, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2024.1443651","article-title":"Classification, biology and entomopathogenic fungi-based management and their mode of action against Drosophila species (Diptera: Drosophilidae): A review","volume":"15","author":"Vivekanandhan","year":"2024","journal-title":"Front Microbiol"},{"key":"B2","unstructured":"University of California Integrated Pest Management Program.
