Παραδείγματα χρήσης PROTHORACIC σε μια πρόταση

• Ecdysone is a prohormone of the major insect molting hormone 20-hydroxyecdysone, secreted from the prothoracic glands.
• The first larval instar has a dark brown head; all other instars have a light fawn head and prothoracic plate.
• However, unpaired prolegs, a ventrally directed truncate head, and prothoracic spiracles on a short respiratory tube differentiate them.
• His most significant contribution was the discovery that neurosecretory cells in the brain of the South American kissing bug, Rhodnius prolixus, secrete a crucial hormone that triggers the prothoracic gland to release prothoracicotropic hormone (PTTH), which regulates the process of metamorphosis.
• The spiracles are located on the ends of wrinkled tube-like spiracular processes, the anterior pair (prothoracic spiracle) are on segment 1 the posterior ones are on segment.
• Larvae are mostly whitish or pinkish, except for a brown head and prothoracic shield, and dark pinacula (sclerotised plates bearing setae).
• When migrating either to prey or a new nest site, workers attach their lower mouthparts to the larvae's prothoracic structure and carry them along their body, ventral side to ventral side, with the larva's head pointing forwards.
