Abstract: The antennal sensilla of the Glyptapanteles liparidis were observed with scanning electron microscope.The results showed that there were ten distinct types of antennal sensilla, including trichoid sensillum, placoid sensillum, chaetic sensillum, pored chaetic sensillum, styloconic sensillum, ampullaceous sensillum, papillatipped cylindric sensillum, poretipped ampullacous sensillum, antrumous sensillum and Bhm′s Bristles. Among which, trichoid sensillum was the largest in number with widest distribution, that was distributed in each node of the antenna. Furthermore, there were most sensilla types and quantity on the antenna flagellums, and there were only trichoid sensillum and chaetic sensillum observed on the scape and pedicel nodes of the antenna. The Bhm′s Bristles only exited in the intersegmental membrane between the head and scape nodes of the antenna.
