Ultrastructure of the antennal sensillae of male and female peach fruit fly, Bactrocera zonata.

Awad AA, Ali NA, Mohamed HO - J. Insect Sci. (2014)

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.

f01_01: Scanning electron micrograph of the antennal segment of male (A) and female (B) Bactrocera zonata. Sc: scape; P: pedicel; F: funiculus; Ar: aristae. High quality figures are available online.

Mentions: The antennae of peach fruit fly, B. zonata, are situated in a frontal depression between compound eyes (the antennal fossa). The antenna is composed of three segments, the scape, pedicel, and funiculus. The scape (short basal segment, semicircle shape) attaches to the pedicel and is movable with it to allow the movement of antenna. Both the scape and the pedicel are heavily covered with microtrichia and bear bristles. The funiculus (third antennal segment) is unsegmented flagellum, while the arista was found on the dorso-proximal end of the funiculus (Figure 1A, B). The total length of the antenna and the length of each segment are shown in Table 1. The antennal segments of females (∼1000 µm) tended to be larger than those of males (∼846.15 µm)
