Scanning electron microscope (SEM) of sensilla on the antennae of first-instar nymph.

(A) Trichoidea sensilla I on the scape. (B) Trichoidea sensilla II on the pedicel. Inset: The high magnification of the basal part of trichoidea sensilla II. (C) Trichoidea sensilla III on the second flagellum. (D) Microtrichia sensilla and campaniform sensilla on the scape. Inset: The high magnification of the central sunken of campaniform sensilla. (E) Coeloconica sensilla I on the pedicel. (F) Coeloconica sensilla II on the second flagellum. TRI I, II and III are trichoidea sensilla I, II and III; MIC, microtrichia sensilla; CAM, campaniform sensilla; COE I and II, coeloconica sensilla I and coeloconica sensilla II. These sensilla on C. lividipennis antennae at other stages were the same, only those in first-instar nymphs are shown here.
