Analyses of the dorsal abdominal glands of fourth- and fifth-instar nymphs of the bed bud, Cimex lectularius L. (Hemiptera: Cimicidae), indicated the predominant constituents were (E)-2-hexenal and (E)-2-octenal, with lesser amounts of 4-oxo-(E)-2-hexenal and 4-oxo-(E)-2-octenal. The latter two compounds have not been reported previously as occurring in bed bugs. There were no differences in the chemical composition of the dorsal abdominal glands excised from exuviae left behind by either male or female adults, nor from glands excised from fourth-instar exuviae. Because the two oxo-aldehydes made up at least 16% of the gland contents, further study of the functional role of these chemicals seem advisable.
对第四和第五龄若虫的腹部背腺进行分析，表明床虱（Cimex lectularius L.）（半翅目：臭虫科）的主要成分是（E）-2-己烯醛和（E）-2-辛烯醛，少量的 4-氧代-（E）-2-己烯醛和 4-氧代-（E）-2-辛烯醛。后两种化合物以前并未报道过存在于床虱中。从雄性或雌性成虫留下的蜕皮中切除的腹部背腺，以及从第四龄蜕皮中切除的腺体，其化学成分没有差异。由于这两种氧代醛至少占腺体含量的 16%，因此进一步研究这些化学物质的功能作用似乎是明智的。
