Scanning Electron Microscopic Observation on Sensilla of the Antennal, Ovipositor and Abdomen in Female of Pachycrepoideus vindemmiae

The antennal, ovipositor and abdomen of female wasp Pachycrepoideus vindemmiae were observed with scanning electron microscopy (SEM). The results indicated that eight types of sensilla, namely B?hm bristles, chaeticum sensilla，trichodea sensilla, placoid sensilla, basiconic mastoid sensilla, thick walled chemoreceptor, thin walled chemoreceptor and sensory pore, were found on the surface of the antenna. Three types of sensilla, namely trichodea sensilla, chaeticum sensilla and bud-shaped sensilla were found on the terminal abdomen. Four types of sensilla, namely trichodea sensilla, chaeticum sensilla, bud-shaped sensilla and sensory pore, were found on the ovipositor. The types, numbers, morphological characteristics and the relative positions of these sensilla were also depicted.
