胸节

翅原基是家蚕成虫盘之一，位于第2和第3胸节的两侧，分别发育为成虫的前后翅。

The wing disc is one of the imaginal discs of the silkworm , which locates the two sides of the2nd and3rd thoracic section and grows separately into adult wing .

并胸腹节具明显的四齿，侧齿大，中齿小；

Propodeum with four teeth , lateral teeth bigger and middle teeth smaller ;
