The chemical composition of phloem sap is very important in understanding the mechanism of host resistance of rice tothe whitebacked planthopper (WBPH), Sogatella furcifer-α, a phloem-feeder. Using the stylectomy method, 30d oldplants’phloem sap of rice varieties Zhefu 802 and TN1 , which were susceptible to WBPH, were collected by cutting the stylet of WBPH when the WBPH were sucking the phloem sap of rice.
