An accurate and rapid method for identifying the sex of Euzophera pyriella pupa and adult was described in this paper.By observing abdominal morphological characteristics of E.pyriella pupa and adult,some significant differences between male and female were found.In female pupa,one shorter suture exists in the middle of the 8th abdominal segment with the average length of 65-70μm and the suture's two sides were smooth,while on the male pupa,a lump on each side of a longer suture(with the average length of 100-110μm)formed by genital pore on the 9th abdominal segment was obviously visible.The female adult had round abdominal end,while the male adult had a forcipate one with annular filaments.
