| 中文摘要: |
| 北京幽灵蛛( Pholcus beijingensis )体表的微感受器包括毛状感受器(触毛、听毛、味觉毛和刺)、裂缝状感受器(单个裂缝器、竖琴器)和跗节器等。扫描电镜观察显示,北京幽灵蛛体表的毛状感受器数量最多,分布最广;其次是裂缝感受器;此外,每个跗节末端具有一个跗节器。除触毛在整个身体表面均有分布外,其他毛状感受器(听毛、味觉毛、刺)以及竖琴器和跗节器等均只在附肢分布。微感受器在各条步足分布的类型和数量一致,但步足各节不同。北京幽灵蛛体表的微感受器类型及其着生位置在雌雄间无差别,除成群分布的裂缝感受器在雌蛛步足的数量多于雄蛛外,其他类型微感受器的数量也没有明显性别差异。 |
| 英文摘要: |
| Spiders are sensitive to various stimuli. To understand the sensing mechanism, microreceptors on body surface of the spider Pholcus beijingensis were studied by scanning electronic micrograph (SEM). Four kinds of sensory hairs including tactile hair, trichobothrium, gustatory hair and spine, were found. Among these hairs, tactile hairs grow on all over the body surface while others just present on appendages. There are not obvious sexual differences in type and distribution of the microreceptors in the spider P.beijingensis , while females have much more single slit sensilla, which distributed in group on the femur, than males. |
