The stinkbug's volatile compositions would alter very much before and after stinkbugs were disturbed or irritated, which caused the alarming effect. An efficient headspace solid-phase microextraction sampling method was established to study the alarming volatile characteristics and potential alarming volatiles of stinkbugs (Tessaratoma papillosa) followed by gas chromatography-mass spectrometry detection. The number of volatiles identified was 16 and 22 before and after stinkbug irritation, respectively. ⋯ The variety of the stinkbug alarming volatile characteristics before and after irritation was specified by common model strategy. Tridecane, [E]-2-hexenal, dodecane, [E]-2-hexen-1-ol acetate, and 2,3-dimethyl-1-pentene contributed most to the various alarming volatile characteristics before and after irritation, which might be the potential alarming volatiles. It is hoped that this work will provide useful information for insect control.
