Figure 1


Fig. 1. Electron micrographs of the male antenna in Ostrinia furnacalis. (A) Scanning micrograph of the basal flagellomer of the antenna. Large numbers of sensilla trichodea (green arrowheads) occur at the medial and lateral part of the ventral surface of the antenna. Basiconic sensillum (ba), coeloconic sensillum (co), auricillic sensillum (au), chaetic sensillum (yellow arrowhead) and styloconic sensillum (yellow arrow, behind s. trichodeum) are also visible. For morphological details of the sensilla, see text. Note the honeycomb-like surface sculpturing of the antennal cuticle. Scales occur on the dorsal surface. Bar, 20 µm. (B) Transmission micrograph of a basal transverse section through a sensillum trichodeum containing three unbranched outer dendritic segments (arrow) in the sensillum cavity. Honeycomb-like surface cuticle (arrowhead) surrounds the sensillum. This region lacks wall pores. Bar, 1 µm. (C) Middle section of an s. trichodeum containing three unbranched outer dendritic segments (arrow). Wall pores (arrowheads) were seen as less electron-dense areas in the wall cuticle. Note that the sensillum was cut obliquely and that inner structures of the outer dendritic segments were unclear because of incomplete fixation. Bar, 1 µm.
