Notes on Life-History and Taxonomy of Ceruraphis eriophori (Wlk.) and Neoceruraphis viburnicola (Gill.), and a Description of the Apterous Viviparous Female of Neoceruraphis viburnicola (Gill.) (Homoptera: Aphididae)

Abstract

In New Brunswick, Ceruraphis eriophori (Wlk., 1848) and Neoceruraphis viburnicola (Gill., 1909) are readily found in spring and autumn on their Viburnum hosts. I have collected both species from the curled leaves of these primary hosts (C. eriophori from Viburnum lantana L. and V. opulus L. and N. viburnicola from V. opulus var. roseum L. and V. trilobum Marsh.) In Colorado, Palmer (1952) recorded borh species from V. opulus var. sterile (= V. opulus var. roseum).The known secondary host plants of C. eriophori in Europe are species of Carex, Eriophorum, Luzula, and Typha (Börner, 1952); in North America, Cyperus virens Michx. is the only one reported (Palmer, 1952). The secondary hosts of N. viburnicola have not been recorded (Palmer, 1952; Shaposhinkov, 1956), nor has the apterous viviparous female been described.
