对信息素腺体提取物、从切除的信息素腺体收集的挥发物和从呼叫雌性收集的挥发物进行气相色谱和质谱分析。除十四醛、（Z）-9-十四烯醛、十六醛、（Z）-7-十六烯醛、（Z）-9-十六烯醛和（Z）-11-十六烯醛外，还从腺体提取物中鉴定出十四醇、（Z）-9-十四烯醇、十六醇和（Z）-11-十六烯醇。只有6种醛类成分在腺体和雌性挥发物中被发现。采自雌蜂的挥发物中，十四醛、9-十四烯醛、十六醛、7-十六烯醛、9-十六烯醛和11-十六烯醛的平均含量分别为13.0%、18.1%、7.3%、0.6%、1.0%和60.0%。使用橡胶隔膜制定释放女性挥发性混合物的生物测定表明，所有六个醛组分在近距离男性生殖行为中发挥重要作用。从六组分共混物中删除（Z）-9-十六烯醛减少了交配尝试的次数，而（Z）-7-十六烯醛对所有近距离行为产生了微妙的影响。十四醛影响了雄性近距离重新定向的次数。删除十六醛从六个组成部分的混合物导致显着减少的次数男性登陆。比较六组分合成混合物（释放量略低于1雌性当量/小时）与呼叫雌性动物表明，六组分混合物在诱导所有监测的行为方面与雌性动物没有区别。
Gas chromatographic and mass spectral analyses were conducted on pheromone gland extracts, volatiles collected from excised pheromone glands, and volatiles collected from calling females. In addition to tetradecanal, (Z)-9-tetradecenal, hexadecanal, (Z)-7-hexadecenal, (Z)-9-hexadecenal, and (Z)-11-hexadecenal, four other compounds, tetradecanol, (Z)-9-tetradecenol, hexadecanol, and (Z)-11-hexadecenol, were also identified from gland extracts. Only the six aldehyde components were found in gland and female volatile collections. The mean percentage of components identified from volatiles collected from calling females was 13.0% tetradecanal, 18.1% (Z)-9-tetradecenal, 7.3% hexadecanal, 0.6% (Z)-7-hexadecenal, 1.0% (Z)-9-hexadecenal, and 60.0% (Z)-11-hexadecenal. Bioassays using rubber septa formulated to release the female volatile blend indicated that all six aldehyde components play major roles in close-range male reproductive behavior. Deletion of (Z)-9-hexadecenal from the six-component blend reduced the number of copulation attempts while (Z)-7-hexadecenal exerted subtle effects on all close range behaviors. Tetradecanal affected the number of times males reorient from close range. Deletion of hexadecanal from the six-component blend resulted in a significant reduction in the number of times males landed. Comparison of the six-component synthetic blend (released at somewhat less than 1 female equivalent per hour) with calling females indicated that the six-component blend was indistinguishable from the females in inducing all of the behaviors monitored.
