【Aim】 The purpose of this study was to clarify the types, quantity, distribution and morphological structure of sensilla on the antenna of adult tea moth (Agriophara rhombata Meyr). 【Method】 Using scanning electron microscope to observe the ultrastructure of various sensilla on the antennae of female and male adult A. rhombata. 【Result】A total of 8 kinds of sensilla were found on the antennae of A. rhombata, the y were Böhm's mane (2 subtypes), scale-shaped sensilla, thorn-shaped sensilla (2 subtypes), cavity cone sensilla, bolt cone, cone, hairy (4 subtypes) and tongue. 【Conclusion】There are sexual dimorphisms in the antennal sensilla of female and male adults of A. rhombata, and the species of sensilla in male and female moths are the same. The research will provide an experimental basis for the study of the communication and behavioral mechanism of A. rhombata.
