title: Post-embryonic determination of the ecdysial line in the cockroach: evidence for pattern regulation in the medio-lateral axis.
abstract: By removing or transplanting sections of the ecdysial line in the cockroach Gromphadorhina portentosa, pattern regulation in medio-lateral axis of an insect has been demonstrated. The line can reform after sections have been removed and when epidermal grafts from either side of the midline are grafted with confronting medial edges. The results are explicable in terms of known mechanisms for pattern regulation in insects.
