as attractants, there have been no studies investigating the identity or activity of rectal gland secretions or emission profiles of this species. The present study (1) identifies the chemical profile of volatile compounds produced in rectal glands and released by B. frauenfeldi, (2) investigates which of the volatile compounds elicit an electroantennographic or electropalpographic response, and (3)
Bactrocera frauenfeldi (Schiner)(双翅目:实蝇科)是巴布亚新几内亚特有的一种多食性果蝇害虫物种,已在几个太平洋岛屿和澳大利亚定居。尽管它对许多作物具有重要的经济意义,化学介导的性交流在实蝇的生殖生物学中起着关键作用,以及信息素作为引诱剂的潜在应用,但还没有研究调查直肠腺的特性或活动该物种的分泌物或排放特征。本研究 (1) 确定了直肠腺中产生并由 B. frauenfeldi 释放的挥发性化合物的化学特征,(2) 调查哪些挥发性化合物会引起触电图或触电图反应,(3) 研究腺体排放作为吸引配偶的性信息素的潜在功能。通过气相色谱-质谱法分析了来自 B. frauenfeldi 的性成熟雄性和雌性的直肠腺提取物和顶空收集物。男性直肠腺体含有 (E,E)-2-ethyl-8-methyl-1,7-dioxaspiro [5.5] undecane 作为主要成分和 (E
