PESTICIDAL GENE AND USE THEREOF

Involved is pesiticidal gene and use thereof， the nucleotide sequence of said pesticidal gene comprises: (a) a nucleotide sequence as shown in SEQ ID NO: 3; or (b) a nucleotide sequence as shown in SEQ ID NO: 4;. The pesticidal gene of present invention is particularly suitable for expression in monocotyledonae and notably increases the expression level， stability and virulence of pesticidal protein Vip3Aa. At the same time， in present invention， Sesamia inferens is controlled by the Vip3Aa protein having pesticidal activity against Sesamia inferens， which is produced in the plants. The present invention can protect the whole plant during whole growth period from the harm of Sesamia inferen. Furthermore， it causes no pollution and no residue and provides a stable and thorough control effect. Also it is simple， convenient and economic.
