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.

Scanning electron micrograph of the funiculus of male (A) and female (B) Bactrocera zonata showing different types of sensilla. TrI, II: trichoid sensilla type 1, 2; BsI: basiconica sensilla type 1; Cl: clavate sensilla; CoI, II: coeloconica sensilla type 1, 2. High quality figures are available online.

f04_01: Scanning electron micrograph of the funiculus of male (A) and female (B) Bactrocera zonata showing different types of sensilla. TrI, II: trichoid sensilla type 1, 2; BsI: basiconica sensilla type 1; Cl: clavate sensilla; CoI, II: coeloconica sensilla type 1, 2. High quality figures are available online.

Mentions: C) The funiculus (third antennal segment): The funiculus is the most important antennal segment. It is an elongate and un-segmented flagellum. A large protruding arista extends from the superior edge of the outer surface of the funiculus. The third antennal segment of females (∼576.92 µm) tended to be larger than that of males (∼553.84 µm). Numerous sensilla were found. It is densely covered with microtrichia, which gradually diminished in density from the base to the tip. Four major types of sensilla (trichoid, basiconica, clavate and coeloconica sensillae) were observed on the flagellum (funiculus) of male and female B. zonata. All sensillae were oriented in a direction to the tip of antenna, giving the flagellum a velvety appearance. The funicular sensilla observed in males was greater than in females (Table 4, Figure 4A, B).
