BACKGROUNDBactrocera cucurbitae (Coquillett) is a distructive quarantine insect pest that causes significant economic losses on cucurbit crops. To explore a green control approach, we investigated the behavioral responses of B. cucurbitae larvae and adults to bacterial suspensions, sediments, and supernatants derived from eight gut microbial strains across four distinct genera. The proboscis extension response was used to evaluate the impact of these microbial strains. In addition, using food selection experiments, two‐choice trap methods, and gas chromatography–mass spectrometry, we isolated and identified the predominant volatile compounds in the microbiota supernatants.RESULTSAmong the tested gut microbial strains, Kluyvera , Morganella , and Providencia exhibited notable attraction toward B . cucurbitae . In particular, the supernatant of Providencia M38 revealed the most highly attractive effect on B . cucurbitae larvae, whereas the supernatant of Morganella M72 was highly attractive to B. cucurbitae adults. Primary components present in the supernatant of M38 and M72 were dimethyl disulfide, indole, 2‐nonone, phenethyl alcohol, and 1‐decanol.CONCLUSIONStrains of M38 and M72 displayed remarkable attractive properties for B. cucurbitae larvae and adults, respectively, presenting promising potential for developing a novel attractant for this pest species. © 2025 Society of Chemical Industry.

Bactrocera cucurbitae (Coquillett) 对选定的肠道微生物群上清液的吸引力:对害虫防治的影响
背景葫芦葫芦 (Coquillett) 是一种破坏性检疫性害虫,对葫芦作物造成重大经济损失。为了探索绿色控制方法,我们研究了葫芦芽孢杆菌幼虫和成虫对来自四个不同属的八种肠道微生物菌株的细菌悬浮液、沉积物和上清液的行为反应。喙伸展反应用于评估这些微生物菌株的影响。此外,使用食物选择实验、二选捕集法和气相色谱-质谱法,我们分离并鉴定了微生物群上清液中的主要挥发性化合物。结果在测试的肠道微生物菌株中,Kluyvera、Morganella 和 Providencia 表现出对葫芦芽孢杆菌的显着吸引力。特别是,Providencia M38 的上清液对葫芦芽孢杆菌幼虫具有最强的吸引力,而摩根氏菌 M72 的上清液对葫芦芽孢杆菌成虫具有极强的吸引力。M38 和 M72 上清液中存在的主要成分是二甲基二硫醚、吲哚、2-壬酮、苯乙醇和 1-癸醇。结论M38 和 M72 菌株分别对葫芦幼虫和成虫表现出显著的吸引力特性,为开发该害虫物种的新型引诱剂提供了有希望的潜力。© 2025 化工学会.
