摘　　要：描述了绿翅绢野螟Diaphania angustalis(Snellen)蛹和成虫的雌雄鉴定特征。雌蛹第8腹节腹面中间有1纵裂缝,连接第7腹节与第9腹节,裂缝两侧平坦无突起,第8,9,10节腹面节间呈两个"八"字形凹陷,腹部末端具有7根毛钩,分节明显;雄蛹第8腹节没有裂缝,第9腹节有1纵裂,两侧各有1半圆形瘤状突起,与肛门裂缝间距远小于雌蛹,腹部末端具有8根毛钩,分节较雌蛹不明显。A rapid and accurate method for identifying the sex of Diaphania angustalis pupae was reported. To the female pupae,a longitudinal suture exists on the 8th abdominal segment,and the space around the suture is smooth,there are two splay depression on the surface of the 8th,9th,10 th abdominal segments,and 7 hair hooks at apex abdominis,while to the male pupae,no suture is found on the surface of the 8th abdominal segment,and there is a suture on the 9th abdominal segment where a semicircular lump can be found on each side,abdominal end has 8 hair hooks,and the last abdominal segment is not as obvious as that of female pupa.
