中文摘要：
报道1种根据外部形态特征迅速、准确区分菜粉蝶Pieris rapae L.蛹雌雄的方法。实体显微镜检表明，雌蛹第8腹节有1生殖孔，第9腹节有1产卵孔，两孔之间连成1条长纵裂缝；而雄蛹只在第9腹节有1个生殖孔，形成的纵裂缝短。
英文摘要：
Stereomicroscope was used to distinguish between male and female of Pieris rapae L. pupae rapidly and reliably. It showed that one longer suture existed between the genital pore on the 8th abdominal segment and the oviporus on the 9th abdominal segment of female pupae, and one shorter suture formed by genital pore on the 9th abdominal segment of male pupae.
