Application of insecticidal protein

Abstract

The invention relates to application of insecticidal protein. A method for controlling chilotraea infuscatellus insects comprises the step of enabling the chilotraea infuscatellus insects to be at least in contact with Vip3A protein. The application has the characteristic that the chilotraea infuscatellus insects are controlled by generating the Vip3A protein capable of killing chilotraea infuscatellus in a plant body; compared with an agricultural control method, a chemical control method and a physical control method in the prior art, the application has the advantages that whole-growing-period and whole-plant protection is carried out on the plant so as to control the invasion of the chilotraea infuscatellus insects, no pollution is caused, no residue is generated, the effect is stable and thorough, and the application is simple, convenient and economic.

Description

technical field

[0001] The invention relates to an application of an insecticidal protein, in particular to an application of a Vip3A protein expressed in plants to control damage to plants by the pod borer. Background technique

[0002] Chestnut gray borer (Chilo infuscatellus), also known as sugarcane two-spot borer, belongs to Lepidoptera moth family. It is widely distributed in Southeast Asia, South Asia and China. In China, it mainly damages gramineous crops, such as corn, sorghum, millet and sugarcane. Millet ash borer is a stem-boring pest, which can cause dead plants after the plant is damaged. Under normal circumstances, the spring valley area and the spring-summer valley mixed-seeding area have heavy occurrences, and the summer valley area has light damage.

[0003] Corn is an important food crop in China. With the strengthening of the global greenhouse effect, the temperature has continued to rise in the past two years, and the types and numbers of insect pests h...
