Nilaparvata lugens NlMATH3 gene and application thereof in prevention and treatment of Nilaparvata lugens

The invention discloses a nilaparvata lugens NlMATH3 gene and application of the nilaparvata lugens NlMATH3 gene in prevention and treatment of nilaparvata lugens. The nucleotide sequence of the nilaparvata lugens NlMATH3 gene is as shown in SEQ ID NO. 1. The invention discloses the application of the NlMATH3 gene of the brown planthopper as the target spot in prevention and treatment of the brown planthopper for the first time, ovarian development and egg laying quantity of the brown planthopper can be influenced by silencing the NlMATH3 gene, the generation quantity of offspring of the brown planthopper is reduced, and the survival rate of eggs is reduced, so that the purpose of preventing and treating the brown planthopper is achieved. 本发明公开了褐飞虱NlMATH3基因及其在防治褐飞虱中的应用。褐飞虱NlMATH3基因的核苷酸序列如SEQ ID NO.1所示。本发明首次公开褐飞虱NlMATH3基因作为靶点在防治褐飞虱中的应用，通过沉默NlMATH3基因可以影响褐飞虱的卵巢发育和产卵数量，使褐飞虱后代产生数量减少及卵成活率下降，从而达到防治褐飞虱的目的。
