Abstract

Antennal sensilla of the Cochliomyia hominivorax were studied by scanning electron microscopy. Thirteen subtypes of sensilla were identified in the fly antenna. In the antennal funiculus, nine subtypes were found: one trichoid, three basiconic, and five coeloconic. Among these, olfactory sensilla were morphologically recognized. Long bristle sensilla presenting various sizes and distribution patterns were observed in the scape and pedicel. In this segment, two other types of tricoid sensilla were still observed. The three antennal segments were shown to be coved by smaller spinules of the microtrichia type. No type of sensillum was seen in the aristas of C. hominivorax. Consistent differences between the sexes in typology, topography, and quantity of antennal sensilla were verified. The great variety of sensillary subtypes, presenting wall pores and/or grooves, found in the funiculus of C. hominivorax, indicates the olfaction should play an important role in this species behavior and communication. The data of the current study, besides corroborating in the amplification of the morphologic and ultrastructural knowledge of C. hominivorax, can foment future electrophysiological studies for the development of volatile semiochemicals, to be uses as attractants in traps, as a new alternative to monitoring and/or controlling this fly.
