Abstract： The feeding behaviour of Schlechtendalia chinensis (Bell) fundatrix on its primary hostplant Rhus chinensis Mill was monitored using an electrical penetration graph (EPG). 7 EPG waves were obtained on leaflets or leafwings; np, C (A+B+C), pd, E1, E2, F and G waves. The tissue of leaflets or leafwings on which S. chinensis had fed were sectioned and examined with an optical microscope. The results revealed that the aphid stylets had mostly just touched the phloem. Based on these results we conclude that S. chinensis fundatrix obtains food mainly from the phloem.
