A method for improving plant insect resistance includes providing target genes derived from insects. Constructs based on the nucleotide sequences of these target genes are designed to form interfering molecules. After being eating by insects, the plant can significantly inhibit expression of corresponding genes in insects. This inhibition is not affected by barrier of the insect digestive systems. The method can improve the insect resistance of plants, reduce pesticide applications, lower the costs of agricultural production, and protect the environment.

Method for improving plant resistance to insects

A method for improving insect resistance of plants, in which dsRNA of insect's gene is expressed in plants by using transgenic technique, and then the interfering RNAs are formed in the plants. The interfering RNAs then enter into insects' bodies after being ingested by the insect that eats the plant, and conduct RNA interference against the target gene, thereby expression of the target gene is suppressed by RNA interference. A new plant-mediated method for improving insect resistance by suppressing the growth of insects by RNA interference mechanism.
