Abstract

Abstract Detached strawberry leaves of the cultivar ‘Senga Sengana’ representing different levels of nitrogen content were fed to adult vine weevils, Otiorrhynchus sulcatus. The fecundity of the weevils was investigated in connection with their consumption and digestion of the strawberry leaves. A significant reduction in fecundity was found when the nitrogen content of strawberry leaves decreased from 2.2–2.0% N of leaf dry matter. A significant positive correlation between the weevil's fecundity and its digestion of strawbery leaves was found.
