as attractants, there have been no studies investigating the identity or activity of rectalglandsecretions or emission profiles of this species. The present study (1) identifies the chemical profile of volatile compounds produced in rectalglands 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

Pheromones are biologically important in fruitfly mating systems, and also have potential applications as attractants or mating disrupters for pest management. Bactrocera kraussi (Hardy) (Diptera: Tephritidae) is a polyphagous pest fruitfly for which the chemical profile of rectalglands is available for males but not for females. There have been no studies of the volatile emissions of either sex
信息素在果蝇交配系统中具有重要的生物学意义,并且还具有作为害虫管理的引诱剂或交配干扰剂的潜在应用。 Bactrocera kraussi (Hardy)(双翅目:实蝇科)是一种杂食性害虫果蝇,其直肠腺的化学特征仅适用于雄性,但不适用于雌性。目前还没有关于性别挥发性排放或对这些化合物的电生理反应的研究。本研究(i)通过气相色谱-质谱(GC-MS)建立了两性B. kraussi直肠腺内容物和挥发物的化学特征,(ii)评估了气相色谱对已鉴定化合物的检测 -触角电图检测(GC-EAD)和触角电图检测(GC-EPD)。在雄性B. kraussi 的直肠腺中鉴定出 16 种化合物,在雌性 B. kraussi的直肠腺中鉴定出 29 种化合物。在这些化合物中,有 5 种在雄性的顶部空间中检测到,13 种在雌性的顶部空间中检测到。 GC-EPD 测定记录了两性针对 ( E , E )-2,8-二甲基-1,7-二氧螺[5
