摘要: 通过显微解剖,结合透射电镜和扫描电镜,观察比较了条背萤Luciola substriata幼虫两个不同发育阶段呼吸系统的差异。结果表明:1~2龄幼虫的呼吸系统中只有气管无气囊,3~6龄幼虫的呼吸系统中气管和气囊并存。1~2龄幼虫的尾气门和3~6龄幼虫的腹部侧气门及尾气门结构没有差异。透射电镜观察提示条背萤1~2龄幼虫体壁上的毛状物为气管鳃。

Abstract: The structure of respiratory system during the 1st-2nd instars and the 3rd-6th instars of Luciola substriata larva was observed using micro-dissection, transmission electron microscope (TEM) and scanning electron microscope (SEM). The results indicated that the 1st-2nd instar larva had trachea without air sacs, while the 3rd-6th instar larva had trachea and air sacs in the respiratory system. The structure of the posterior spiracles of the 1st-2nd instar larva was the same as that of the 3rd-6th instar larva. Observations by TEM suggest that the hairs on the culticle are tracheal gills.
