摘要: 观察了多音天蚕Antheraea polyphemus及柞蚕I>Antheraea pernyi 雄蛾触角上毛形感器 (Sensillum trichodeum)的形态、数量和分布,并用单细胞记录方法研究嗅觉感受细胞对性外激素组分的反应特性。两种雄蛾的触角上的每个毛形感器内都存在有1至3个数目不等的嗅觉感受细胞,即AC1-细胞,Ac2-细胞和AL-细胞,它们分别对各自的性外激素组分产生具有高度特异性的反应。

Abstract: The number, shape and distribution of sensilla trichodea on the antennae of male silkworm moths Antheraea polyphemus and A. pernyi were observed and their quantitative difference was measured. The specificities of response to the components of sex pheromones of olfactory cells were investigated by single cell recording. The result indicated that there were1to 3 receptor cells in each olfactory sensillum on the antennae of male moths and they could be nominated as the AC1-cell, AC2-celland Alcell respectively. It was shown that each type of the receptor cells was highly specialized to one kind of the the components of the sex pheromones and there was certain difference in the response specific to the insect species.

Key words: Antheraea polyphemus——Ansheraea pernyi——sex pheromone ——single cell recording
