摘要
研究了普通齿蛉Neoneuromus ignobilis Navás幼虫的呼吸系统及其呼吸行为。结果表明:普通齿蛉幼虫为全气门式(10对气门)呼吸系统,前中胸、中后胸之间、腹部8节各有1对气门,腹部8节各有气管鳃1对,前6对细短,管状,有较短绒毛,后2对气管鳃较粗长,呈羽毛状。腹部1～7节各有1对毛簇,第8腹节无毛簇。侧纵干气管较粗,4束,自前胸前缘部分成左右2组,每组两根侧纵干气管,向胸腹部延伸,二级气管分别伸达各个气门和毛簇,腹部每节由毛簇处的二级气管分支而来的三级气管相连或延伸至消化道等处。气管鳃中无气管。有毛簇呼吸、气门呼吸和体壁呼吸3种呼吸方式,在水中以毛簇呼吸为主,在陆上进行气门呼吸和体壁呼吸。
The respiratory system and behavior of the larva of Neoneuromus ignobilis Navás were investigated.10 pairs of spiracles are located on the prothorax,mesothorax and metathorax,and the 8 abdominal segments.The first six pairs of spiracles are slender,short and tubular and have short villi.The last two pairs are thicker and longer and appear feathery.There are a pair of tufts located on the 1st to 7th abdominal segments,but none on the eighth abdominal segment.The lateral and vertical tracheas,4 beams in total,are thicker.They are divided into two groups located on the left and right sides from the front prothorax all of which extend to the thorax and abdomen.The second level tracheas extend into every spiracle and tracheal gill tufts.The third level tracheas branch from the second level tracheas and link,or extend,into the alimentary canal in every abdominal segment.There are no tracheas in the tracheal gills.There are 3 kinds of respiratory behaviors;using the tuft mass,spiracles and body wall,mainly using the tuft mass in water and mainly using the spiracles and body wall on land.
