Abstract

Beguinot (1) early described the morphology and anatomy of galls induced on Cuscuta by species of Smicronyx, the genus containing the dodder gall-weevils. Yuncker (4) referred to swellings on stems and flower pedicels of dried herbarium material of Cuscuta and suggested that these galls were caused by an insect, then unidentified because of the condition of the specimens. Weiss and West (3) described galls from Monmouth Junction, New Jersey, on Cuscuta cephalanthi Englm. caused by the dodder gall-weevil, Smicronyx sculpticollis Casey. Gertz (2) reported galls from Sweden on the stems and flower pedicels of Cuscuta europaea L. caused by another species of dodder gall-weevil, Smicronyx jungermanniae Reich. This insect is described by Gertz as rare for Sweden and Scandanavia, but of common occurrence in Central Europe and Italy. Later, Yuncker (5) had occasion to examine numerous, fresh, insect-induced galls on Cuscuta pentagona L. collected near Lafayette, Indiana. He concluded that these swellings were caused by Smicronyx sculpticollis, and that galls previously found by him on dried specimens of Cuscuta resembled those induced by this species of insect.
