Published online by Cambridge University Press: 31 May 2012
Extract
To our knowledge, reports of Betula spp. resistance against damage caused by the birch leafminer, Fenusa pusilla (Lepeletier), have not been published. Becker (1938), Friend (1933), and Johnson and Lyon (1976) stated that B. populifolia Marsh., B. papyrifera Marsh., and B. alba L. are the most commonly attacked species. Friend (1933) and Johnson and Lyon (1976) stated that B. lenta L., B. alleghaniensis Britt, and B. nigra L. have never been observed infested or are rarely fed upon.
