In order to identify the main types, morphological characteristics and distribution of sensilla on the adult Trichogramma pintoi Voegele, in this study, the types and morphological structures of sensilla on the antennae and abdominal ends were observed and described using scanning electron microscopy(SEM). The results showed that there were seven types of sensilla on the antennae of the T. pintoi, namely, the sensilla trichodea, the sensilla chaetica, the B?hm bristles, the sensilla coeloclnica, the sensilla placodea, the sensilla campaniformia and the sensilla falcatas, among which the sensilla trichodea was the most numerous. At the end of the abdomen, there were four types of sensilla, namely, sensilla trichodea, sensilla chaetica, B?hm bristles and sensilla campaniformia. The present study perfects the study of the ultrastructure of the sensilla of the Trichogramma, and provides a morphological basis for the subsequent study of chemical communication mechanism and biocontrol development and utilisation of the Trichogramma. |
