The composition of stink bug allomones is similar for most species and includes hydrocarbons, as well as saturated and unsaturated aldehydes and esters. Analysis of extracts of the metathoracic glands of seven pentatomid species from different genera by gas chromatography/Fourier transform-infrared (GC/FT-IR) showed that the compound previously thought to be 1-tridecene actually showed characteristic bands of an internal as well as terminal double bond, the former compound having (Z)-configuration. The mass spectrum of an epoxy-derivative of the natural material demonstrated that the internal double bound was located at C4. GC/FT-IR and co-injections with synthetic standards on different capillary columns proved that all these stink bugs had 1-tridecene and (Z)-4-tridecene in their defensive secretions.
臭虫信息素的成分在大多数物种中相似,包括碳氢化合物,以及饱和和不饱和的醛和酯。通过气相色谱/傅里叶变换红外光谱(GC/FT-IR)对来自不同属的七种半翅目昆虫的后胸腺提取物进行分析表明,以前被认为是 1-十三烯的化合物实际上显示出内部和末端双键的特征带,前一种化合物具有(Z)-构型。天然物质的环氧化衍生物的质谱表明,内部双键位于 C4 处。GC/FT-IR 和在不同毛细管柱上与合成标准品的共注入证明,所有这些臭虫在它们的防御分泌物中都有 1-十三烯和(Z)-4-十三烯。
