Abstract
In no-choice laboratory tests, young leaves from trees of Betula davurica Pall. Fl. Ross., Betula maximowicziana Reg., Betula schmidtii Reg., and Betula costata Trautv. exhibited 95–100% reductions in oviposition by the birch leafminer Fenusa pusilla (Lepeletier) compared with leaves from Betula populifolia Marsh. Visible absorbance ratios (500 nm: 400 nm) of aqueous supernatants from leaves which exhibited high reductions in oviposition were 2.5- to 4-fold greater than ratios from leaves of B. populifolia. Results suggest these trees offer high resistance against birch leafminer damage and that absorbance characteristics of supernatants from young leaves can be used to detect high levels of resistance.
