Abstract:
Sensilla trichodea of the silk moths, Antheraea pernyi and Bombyx mori, were reconstructed from serial sections after freeze substitution. The volume and surface area of the different sensillar cells were calculated from the area and circumference of consecutive section profiles. A. pernyi and B. mori differ largely in the size of the sensory hair and the larger outer dendritic segments as well as in the volume of the receptor lymph within the hair, while there are only small differences regarding inner dendritic segments, receptor-cell somata, trichogen and tormogen cells and the volume of the receptor lymph below the hair base.
