The invention provides a method for improving Metarhizium anisopliae to kill German cockroach by interfering with genes and its application, belonging to the technical field of biological control. The present invention finds for the first time that the use of RNAi technology to down-regulate the gene expression of Akirin, Bgchi or CYP4G19 can effectively reduce the resistance of the German cockroach to pathogenic fungi (such as Metarhizium anisopliae), making the German cockroach especially resistant to high-efficiency The cypermethrin strain of German cockroach has increased sensitivity to pathogenic fungi (such as Metarhizium anisopliae), thereby effectively improving the poisoning effect of biological insecticides, so it has good practical application value. |
