Electroantennographic and single sensillum recordings were performed on male pine sawfly, Neodiprion sertifer, antennae. Responses to the sex pheromone component (2S, 3S, 7S)- 3,7-dimethyl-2-pentadecenyl (diprionyl) acetate (SSS:OAc), to the behavioral inhibitor (2S, 3R, 7R)-diprionyl acetate (SRR:OAc), to the six other enantiomers of diprionyl acetate, and to the biosynthetic precursor diprionol were recorded. Responses to trans-perillenal, a monoterpene identified in female gland extracts and to (2S, 3S, 7S)-diprionyl propionate (SSS:OPr), a field attractant for N. sertifer and some related sawfly species were also recorded. EAG recordings demonstrated a high antennal sensitivity to SSS:OAc and to SSS:OPr. A somewhat lower response was elicited by SRR:OAc. Single sensillum recordings revealed 8-12 different cells firing in each sensillum, corresponding to the number of cells observed in earlier morphological investigations. Out of these cells all, except one, responded to SSS:OAc and to SSS:OPr. No differences in the response to the two components could be observed. The largest amplitude cell in each sensillum was specifically tuned to the behavioral antagonist, SRR:OAc. The pheromone perception system encountered in male pine sawflies thus differs clearly from that observed in moths.
对雄性松叶蜂（Neodiprion sertifer）的触角进行了触角电图和单感器记录。记录了对性信息素成分（2S, 3S, 7S）-3,7-二甲基-2-十五碳烯基（二普里翁基）乙酸酯（SSS:OAc）、行为抑制剂（2S, 3R, 7R）-二普里翁基乙酸酯（SRR:OAc）、二普里翁基乙酸酯的其他六种对映体以及生物合成前体二普里翁醇的反应。还记录了对在雌虫腺体提取物中鉴定出的单萜反式紫苏醛以及对（2S, 3S, 7S）-二普里翁基丙酸酯（SSS:OPr）（一种对松叶蜂和一些相关叶蜂种类具有田间引诱作用的物质）的反应。触角电图记录表明触角对SSS:OAc和SSS:OPr具有高敏感性。SRR:OAc引起的反应略低。单感器记录显示每个感器中有8 - 12个不同的细胞放电，这与早期形态学研究中观察到的细胞数量相对应。在所有这些细胞中，除了一个之外，其他细胞都对SSS:OAc和SSS:OPr有反应。对这两种成分的反应未观察到差异。每个感器中振幅最大的细胞对行为拮抗剂SRR:OAc具有特异性调谐。因此，雄性松叶蜂中遇到的信息素感知系统与蛾类中观察到的明显不同。
