Title:
INSECTICIDAL PROTEIN COMBINATION, AND INSECT RESISTANCE MANAGEMENT METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2018/090714
Kind Code:
A1
Abstract:
An insecticidal protein combination, and insect resistance management method for same. The insect resistance management method comprises enabling Ostrinia furnacalis to contact at least the protein Cry2Ab and the protein Cry1Ac. By employing two types of insecticidal proteins, Cry1Ac and Cry2Ab, to effectively delay or prevent Ostrinia furnacalis from having resistance, the present invention realizes pest control of Ostrinia furnacalis, provides superior protection of plants, and stabilizes yields.
