Several species of monophagous jack pine sawflies (Hymenoptera: Diprionidae) were tested in the field and by electroantennograms (EAG) for activity toward the optical isomers of a pine sawfly sex pheromone, the acetate and propionate esters of 3,7-dimethylpentadecan-2-ol.Neodiprion rugifrons andNeodiprion dubiosus were attracted to a mixture of the propionate esters of the 2S,3R,7R and 2S,3R,7S isomers, whereasNeodiprion swainei was attracted to the 2S,3S,7S propionate isomer. Samples containing the 2S,3R,7S propionate isomer elicited the strongest EAG responses in these three species andNeodiprion nigroscutum. The 2S,3S,7S propionate isomer was equally active (EAG) in the case ofN. swainei.
几种单食性的马尾松叶蜂（膜翅目：叶蜂科）在野外和触角电位图（EAG）测试中对马尾松叶蜂性信息素的光学异构体，即 3,7-二甲基十五烷-2-醇的乙酸酯和丙酸酯表现出活性。新松毛虫和双齿新松毛虫对 2S,3R,7R 和 2S,3R,7S 异构体的丙酸酯混合物有吸引力，而松毛虫则对 2S,3S,7S 丙酸酯异构体有吸引力。在这三个物种和黑松毛虫中，含有 2S,3R,7S 丙酸酯异构体的样本引起了最强的 EAG 反应。在松毛虫的情况下，2S,3S,7S 丙酸酯异构体同样具有活性（EAG）。
