In order to establish a tool for a sustainable pest control program, the sex pheromone of H. undalis inhabiting the Mekong Delta was examined. GC-EAD and GC–MS analyses of pheromone gland extracts from the virgin females elucidated three new components, (Z)-11-tetradecenyl acetate (Z11-14:OAc), (Z)-11-hexadecenal (Z11-16:Ald), and (11E,13E)-11,13-hexadecadien-1-ol, in addition to the known pheromone component (11E,13E)-11,13-hexadecadienal (E11,E13-16:Ald). Double bond positions of the two monoenyl components were determined by GC–MS analysis of the pheromone extract treated with dimethyl disulfide. On the other hand, GC–MS analysis of the female body extract detected the unsaturated hydrocarbon (3Z,6Z,9Z)-3,6,9-tricosatriene (Z3,Z6,Z9-23:H). Field examinations of their synthetic compounds indicated the significant role of E11,E13-16:Ald as a major component and a clear synergistic effect of the two monoenyl compounds as a minor component. Although the 3:3:7 mixture of Z11-14:OAc, E11-16:Ald, and E11,E13-16:Ald captured the largest number of males among the tested mixtures, the activity was still quite a bit lower than that of virgin females. However, the 3:3:7:1 mixture, which was prepared by adding a small amount of Z3,Z6,Z9-23:H to the 3:3:7 ternary lure, succeeded in attracting males more powerfully than the females did. This strong synergistic effect was not observed when the triene was added to unmixed E11,E13-16:Ald, indicating important roles of not only the triene but also the two monoenyl compounds as natural pheromone components."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380023718864502020","@type":"Researcher","foaf:name":[{"@value":"Le Van Vang"}]},{"@id":"https://cir.nii.ac.jp/crid/1380023718864502017","@type":"Researcher","foaf:name":[{"@value":"Tran Thanh Thy"}]},{"@id":"https://cir.nii.ac.jp/crid/1380023718864502019","@type":"Researcher","foaf:name":[{"@value":"Duong Kieu Hanh"}]},{"@id":"https://cir.nii.ac.jp/crid/1380023718864502016","@type":"Researcher","foaf:name":[{"@value":"Trieu Phuong Linh"}]},{"@id":"https://cir.nii.ac.jp/crid/1380023718864502018","@type":"Researcher","foaf:name":[{"@value":"Masanobu Yamamoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1380023718864502021","@type":"Researcher","foaf:name":[{"@value":"Tetsu Ando"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"12268615"}],"prism:publicationName":[{"@value":"Journal of Asia-Pacific Entomology"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2020-12","prism:volume":"23","prism:number":"4","prism:startingPage":"935","prism:endingPage":"941"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S1226861520303174?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S1226861520303174?httpAccept=text/plain"}],"createdAt":"2020-08-11","modifiedAt":"2025-10-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390304328103198848","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"トマトキバガ（チョウ目：キバガ科）用合成性フェロモントラップで捕獲された蛾類—近似種ジャガイモキバガとの形態学的識別法—"},{"@language":"en","@value":"Moths Collected with Sex Pheromone Traps for Tomato Leaf Miner, <i>Tuta absoluta</i>, in Japan during 2022 to 2023 with Taxonomic Notes on Its Close Relative <i>Phthorimaea operculella</i>（Lepidoptera, Gelechiidae）"},{"@value":"トマトキバガ(チョウ目:キバガ科)用合成性フェロモントラップで捕獲された蛾類 : 近似種ジャガイモキバガとの形態学的識別法"},{"@language":"ja-Kana","@value":"トマトキバガ(チョウモク:キバガカ)ヨウ ゴウセイセイ フェロモントラップ デ ホカク サレタ ガルイ : キンジシュ ジャガイモキバガ ト ノ ケイタイガクテキ シキベツホウ"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.aspen.2020.08.002"},{"@type":"OPENAIRE","@value":"doi_dedup___::eda9767883c125ca87d61fb5fc84f75c"},{"@type":"CROSSREF","@value":"10.1303/jjaez.2025.53_references_DOI_GOXwJJFZYz6tCfFNqjfywTtOCVJ"}]}
