雷氏黄萤幼虫呼吸系统和呼吸行为

研究雷氏黄萤Luciola leii Fu and Ballantyne幼虫的呼吸系统及其呼吸行为。结果表明:雷氏黄萤幼虫的呼吸系统中只有气管无气囊。前胸、中胸和后胸均分布有气门,无气管鳃,腹部1~8节分布有气门和气管鳃,气门腔基部和气管鳃基部相连,呈"√"状,气管鳃内气管与气门气管相连通。雷氏黄萤幼虫的呼吸行为分为3种:利用胸部气门呼吸、腹部气门呼吸和气管鳃呼吸,其中以腹部气门呼吸为主。

Respiratory system and respiratory behaviors of Luciola leii larvae

The structure of respiratory system and respiratory behaviors of Luciola leii larvae were studied. The results showed that there were only tracheas without air sacs in the whole respiratory system of L. leii larvae. The spiracles were located on prothorax, mesothorax and metathorax, where no tracheal gills were distributed. Both the spiracles and tracheal gills were located on the 1st～8th segments of abdomen and tracheal gills connected with the basement of the atrium which formed the shape of "√ ". The tracheas in the tracheal gills connected with the spiracular trachea. L. leii larvae had three kinds of respiratory behaviors: using thoracic spiracles, abdominal spiracles and tracheal gills to breathe, in which the abdominal spiracles were primarily used.
