Optimizing Aerosol Dispensers for Mating Disruption of Codling Moth, Cydia pomonella L.

abstract：:A study of two related plants (Antirrhinum majus L. and Linaria vulgaris Mill.) containing the same defensive compound (the iridoid glucoside, antirrhinoside) but with reproductive strategies that differ during ontogeny was undertaken. Young leaves are important to plants due to their higher photosynthetic rates and, ...
