The composition of the territorial marking pheromones from mandibular glands of males of the beewolvesPhilanthus crabroniformis, P. barbatus, andP. pulcher have been determined. The structures of the components were elucidated by gas chromatography-mass spectrometry and gas chromatography-Fourier transform infrared spectroscopy. The major compound ofP. crabroniformis is isopropyl tetradecanoate, with somewhat lesser amounts of 2-tridecanone, 3-methyl-3-butenyl tetradecanoate, and 92∶8 (Z)∶(E)-11-eicosen-1-ol. The major compounds ofP. barbatus are ethyl tetradecanoate and hexadecanal, which are present in approximately a 60∶40 ratio. These two compounds comprise over 95% of the neutral lipids. Also present in lesser amounts are ethyl dodecanoate, tetradecanal, hexadecan-1-ol, a Δ (x) -octadecen-1-ol, and octadecan-1-ol. The major compounds ofP. pulcher are ethyl (Z)-7-hexadecenoate and geranylgeraniol acetate, which comprise nearly 90% of the neutral lipid fraction, with smaller amounts of tetradecanal, pentadecanal, and ethyl hexadecanoate; trace amounts of Δ (x) hexadecenal, hexadecanal, and octadecanal are also present.
已确定雄性锯角叶蜂属 Philanthus crabroniformis、P. barbatus 和 P. pulcher 的下颚腺中领土标记信息素的组成。通过气相色谱-质谱和气相色谱-傅里叶变换红外光谱法阐明了这些成分的结构。P. crabroniformis 的主要化合物是异丙基十四酸酯，其次是 2-十三酮、3-甲基-3-丁烯基十四酸酯和 92∶8（Z）∶（E）-11-二十碳烯-1-醇。P. barbatus 的主要化合物是十四酸乙酯和十六醛，它们的比例约为 60∶40。这两种化合物占中性脂质的 95%以上。此外，还存在少量的十二酸乙酯、十四醛、十六烷-1-醇、Δ（x）-十八烯-1-醇和十八烷-1-醇。P. pulcher 的主要化合物是（Z）-7-十六酸乙酯和香叶基香叶醇乙酸酯，它们占中性脂质部分的近 90%，而十四醛、十五醛和十六酸乙酯的含量较少；还存在痕量的Δ（x）十六烯醛、十六醛和十八醛。
