Resistance to whitebacked planthopper (WBPH) in Chinese japonica rice Chunjiang 06 (CJ-06) was mediated by sucking inhibitory and ovicidal mechanism. The ovicidal reponse was a common self-defense mechanism against WBPH in japonica. The ovicidal gene and its chromosomal position had already been identified. The sucking inhibitory nature of CJ-06 caused a define non-preference behavior of WBPH in fields. A single dominant gene governed the sucking inhibition in CJ-06.
