AN AUTORADIOGRAPHIC STUDY OF ENDOCRINE ACTIVITY FOLLOWING FRONTAL GANGLIONECTOMY IN VIRGIN FEMALES OFMELANOPLUS SANGUINIPES(ORTHOPTERA: ACRIDIDAE)

Abstract

Can. Ent. 102: 1083-1088 (1970) The synthetic ability of type-A neurosecretory cells (NSC) and corpus allatum (CA) was investigated autoradiographically in both normal virgin females and those from which the frontal ganglion had been removed. Incorporation of 3H-cystine and 'H-uridine into the hTSC was significantly lower in frontal ganglionectomized insects than in controls. There appeared to be no relationship between the level of isotope uptake and the amount of stainable material in the NSC. Ability of the CA to incorporate 3H-uridine seemed unaffected by the operation.
