摘要
报道1种根据旋幽夜蛾Scotogramma trifolii Rottemberg蛹腹节的外部形态特征迅速、准确区分旋幽夜蛾蛹雌雄的方法。雌蛹第8腹节腹面中央有一纵裂缝,裂缝连接第7、第9腹节,裂缝两侧平坦,无突起,腹部末端分节不明显;雄蛹第8腹节无裂缝,在第9腹节腹面中央有一纵裂缝,裂缝两边各有一半圆状瘤状突起,腹部末端分节较为明显。这对于了解旋幽夜蛾田间性比,观察生物学特征、种群动态及开展预测预报等十分重要。
A method for quickly and accurately sexing clover cutworm(Scotogramma trifolii Rottemberg) pupae according to the morphology of the 8th and 9th abdominal segments is described.Sexing pupae is essential to determine the sex ratio and important for population dynamics research and outbreak forecasting.
