The Japanese orange fly, Bactrocera tsuneonis, infests various citrus crops. While male pheromone components accumulated in the rectal glands are well characterized for Bactrocera, but information regarding the chemical factors involved in the life cycles of B. tsuneonis remains scarce. Herein, several volatile chemicals including a γ-decalactone, (3R,4R)-3-hydroxy-4-decanolide [(3R,4R)-HD], were identified as major components, along with acetamide and spiroketals as minor components in the rectal gland complexes of male B. tsuneonis flies. The lactone (3R,4R)-HD was also identified in female rectal gland complexes. The amount of this compound in mature males was significantly higher than those observed in females and immature males. The lactone (3R,4R)-HD was detected in flies fed with sucrose only, indicating that this lactone is not derived from dietary sources during adulthood, but biosynthesized in vivo. The predominant accumulation of (3R,4R)-HD in mature males also suggests a possible role in reproductive behavior.
日本橙色果蝇(Bactrocera tsuneonis)寄生在各种柑橘作物上。虽然Bactrocera的雄性信息素成分在直肠腺中已经很好地被表征,但是关于B. tsuneonis生命周期中涉及的化学因素的信息仍然很少。在此,几种挥发性化合物,包括γ-十二内酯、(3R,4R)-3-羟基-4-癸内酯[(3R,4R)-HD],以及乙酰胺和螺环酮作为雄性B. tsuneonis果蝇直肠腺复合物中的次要成分被鉴定为主要成分。内酯(3R,4R)-HD也被鉴定为雌性直肠腺复合物中的成分。成熟雄性中这种化合物的含量显著高于雌性和未成熟雄性。内酯(3R,4R)-HD在只喂食蔗糖的果蝇中被检测到,表明这种内酯不是在成年期从饮食中获取的,而是在体内生物合成的。成熟雄性中(3R,4R)-HD的主要积累也表明其可能在生殖行为中起到作用。
