在天蛾 Agrius convolvuli（鳞翅目：天蛾科）中研究了参与性信息素信息处理的神经元通路，该天蛾使用 (E,E)-11,13-十六烯醛 (El 1,E13-16:Ald) 作为单一性信息素成分。我们首先阐明了旋花蛾触角叶的解剖结构。随后，鉴定出触角叶中对 El 1,E13-16:Ald 做出反应的中枢神经元。这些神经元的树突状突起被限制在触角叶的特定肾小球（积云）内。这些神经元的轴突投射到下外侧原大脑和蘑菇体花萼。尽管空旋花中单个神经元的解剖组织和形态与蚕总科中的其他物种相似，但使用积云作为性信息素信息处理的单一途径是该物种的特征。 (C) 2017 Elsevier Ltd. 保留所有权利。
The neuronal pathways involved in the processing of sex pheromone information were investigated in the hawkmoth Agrius convolvuli (Lepidoptera: Sphingidae), which uses (E,E)-11,13-hexadecadienal (El 1,E13-16:Ald) as the single sex pheromone component. We first clarified the anatomical organization of the antennal lobe of A. convolvuli. Subsequently, central neurons in the antennal lobe that responded to El 1,E13-16:Ald were identified. The dendritic processes of these neurons were confined within a specific glomerulus (cumulus) in the antennal lobe. The axons of these neurons projected to the inferior lateral protocerebrum and mushroom body calyx. Although the anatomical organization and morphology of individual neurons in A. convolvuli were similar to other species in the superfamily Bombycoidea, the use of cumulus as the single pathway for sex pheromone information processing was characteristic to this species.
