(2R,3R)-2,3-Epoxy-3,7-dimethyl-6-octenal [(2R,3R)-epoxyneral] was identified as the female sex pheromone from an acarid mite, Caloglyphus sp. (Astigmata:Acaridae), whose phoretic hypopi had been collected from the Cockchafer, Melolontha japonica (Coleoptera: Scarabaeidae). Sexual activity of the males was induced by exposure to a 0.1-1 ng dose of synthetic (2R,3R)-epoxyneral. The enantiomer of the pheromone, (2S, 3S)-epoxyneral, was inactive and its admixture did not inhibit the activity of the natural pheromone. Copyright (C) 1996 Elsevier Science Ltd
在一项研究中,科学家们从一种名为Caloglyphus的螨虫(属于Acaridae科)中识别出雌性性外激素,化学名称为(2R,3R)-2,3-环氧-3,7-二甲基-6-辛烯醛,也称为(2R,3R)-环氧麦杆烯。这种螨虫的拟寄生幼虫阶段是从粪金龟科的Cockchafer,具体来说是Melolontha japonica中分离出来的。
实验中,雄性的性活动可以通过接触0.1到1纳克的合成(2R,3R)-环氧麦杆烯来诱发。研究还发现,这种性外激素的对映异构体,即(2S,3S)-环氧麦杆烯,并没有活性,且当它与天然性外激素混合时,也不会抑制后者的活性。
