Scanning electron micrographs (SEM) of close up view of the distal segment of the maxillary palp of adult Rhyzopertha dominica and their associated sense organs. A Distal segment of the maxillary palp with numerous short s. trichodea (st1) and single large s. digitiformium (SD), note that the apical tip of the palp carry an apical sensory field (ssf); scale bar = 10 µm. B Enlarged view of the apical part of the maxillary palp carried s. styloconica (sst), s. basiconica (sb) and s. ampullacea. Scale bar = 2 µm. C Close up view of s. digitiformium showing longitudinal gutters. Scale bar = 10 µm. D enlarged view of the base of s. digitiformium showing internal pores inside the longitudinal gutters (arrow heads). Scale bars: A 10 µm; B 2 µm; C 10 µm; D 1 µm
