Sensilla on the antennal funiculus of the blow fly, Protophormia terraenovae (Diptera: Calliphoridae)
No full textThe morphology of the antennal funiculus and the external morphological characteristics and distribution
of sensilla of blow fly, Protophormia terraenovae, have been studied using light and scanning
electron microscopy. Cross section of the funiculus is roughly triangular in shape, with an anterior-medial,
anterior-lateral, and posterior surface. The latter presents some large-size pits on restricted lateral and
median areas of the proximal funiculus, and several smaller-size ones close to the pedicel–funiculus
joint. The entire surface of the antennal sub-segment appears densely populated by microtrichia and is
inhabited by seven types of sensilla: one trichoid, two basiconic, one auriculate, one coeloconic, and two
basiconic-like pit sensilla. Trichoid, basiconic, auriculate and basiconic-like types display a multiporous
wall, a feature characteristic of insect olfactory sensilla. It remains to be verified whether or not the coeloconic
structure type has wall pores. The most abundant sensilla are the trichoid ones, which are followed
by the basiconic, coeloconic and auriculate types in a decreasing density order. The basiconic-like pit sensilla
are present only on the posterior funicular surface, unlike the remaining ones which populate the
entire sub-segment. The blow fly’ funiculus displays a significant, even though moderate sexual dimorphism,
the female sub-segment being bigger and presenting a higher number of trichoid and auriculate
sensilla. The presence of multiple wall pores in most of sensilla types implies an olfactory modality
for sensory neurons they accomodate, thus indicating that the blow fly’ funiculus is a plain olfactory
organ
