dorsal trunk growth, open tracheal system
Growth of epithelial tubes that originate from pits in an open tracheal system and grow towards each other to meet and form a continuous open tube called the dorsal trunk. The dorsal trunk extends from the anterior spiracle to the posterior spiracle of the larva and forms the main airway of the insect tracheal system.
