Summary The occurrence of urotensin I (UI)-like immunoreactivity is demonstrated in the midgut of the cricket Gryllus bimaculatus and the cockroach Periplaneta americana. The immunoreactivity is restricted to endocrine cells dispersed in the epithelium of the midgut. The UI-positive endocrine cells are numerous in the cricket, but much fewer in the cockroach. These UI-positive cells are different from bovine pancreatic polypeptide (BPP)-immunoreactive cells which represent a dominant cell type in the midgut of both insects. This study suggests the possibility that the neuropeptide UI or a closely related substance may also occur in animals other than fishes.
