Ultrastructure of the antennal sensillae of male and female peach fruit fly, Bactrocera zonata.
Bottom Line: This study focused on the sensillae found on the antennal segments (scape, pedicel, and flagellum or funiculus that bears the arista) of B. zonata.Numerous microtrichia as well as trichoid (I, II), basiconic, clavate, and coeloconic sensillae were observed on the funiculus.The sensillae found on the funiculus, such as trichoid and basiconic sensillae, were significantly larger in females.

Mentions: B) The pedicel (P; second antennal segment). The pedicel is a cone-like structure that measures ∼284.5 µm in its maximum length, slightly longer than the scape, movable with scape to allow the movement of antenna. It is reinforced and fringed with many types of sensilla (Table 3, Figure 3A, B). The total number of sensilla observed in males was greater than in females. Numerous microtrichia as well as trichoid (TrI, II), cheatica, and basiconica (II) sensilla were observed on the pedicel.
