Abstract
A detailed study of the innervation of the neuroendocrine organs in eight species of Noctuidae has revealed a previously undescribed network of serves. A dorsal branch of the outer pair of nerves connecting the protocerebrum with the corpora cardiaca bears fine nerves extending to the ocellar, antennal, and optic nerves and to the orbital setae. A distinct ventrally directed nerve arising from each corpus cardiacum has branches extending to the optic, maxillary, and palpal nerve and lateral orbital setae. The possible significance of these nerves is discussed in the context of known endocrine functions.
