Electrophysiological studies of pheromone receptor cells keyed to ispdienol were performed in laboratory-raised hybrids of the eastern and western populations of the pine engraver,Ips pini. As previously shown in the parental beetles, the receptor cells keyed to ipsdienol could be classified as two distinct types: one keyed to (+)- and one to (-)-ipsdienol. None of the 20 ipsdienol cells recorded from F1 hybrids were of an intermediate type. Recordings of the summated receptor responses (EAGs) showed no significant difference between parental beetles and hybrids. Similar results were obtained in reciprocal crosses, eastern females with western males and the reverse. Thus, there was no indication that sex-linked alleles determined the specificity of the ipsdienol receptor cell. The ratio between (+) and (-) cells was 14∶6 in the hybrids compared to 1∶12 in the western and 9∶12 in the eastern populations.
对性信息素受体细胞的电生理研究在实验室饲养的松雕象甲的东部和西部种群的杂交种中进行。如以前在亲代甲虫中所示，对异松二烯醇有反应的受体细胞可以分为两种不同的类型：一种对（+）-和一种对（-）-异松二烯醇有反应。从 F1 杂种中记录的 20 个异松二烯醇细胞中没有一个是中间类型的。总和受体反应（EAGs）的记录显示，亲代甲虫和杂种之间没有显著差异。在正反交中也得到了类似的结果，即东部雌性与西部雄性杂交和相反的杂交。因此，没有迹象表明性连锁等位基因决定了异松二烯醇受体细胞的特异性。在杂种中，（+）和（-）细胞的比例为 14∶6，而在西部种群中为 1∶12，在东部种群中为 9∶12。
