1 dsRNA Composition for controlling Spodoptera exigua comprising E. coli expressing dsRNA specific to integrin beta 1 subunit of Spodoptera exigua and method for controlling the larvae of Spodoptera exigua using it

摘要

The present invention relates to a composition for controlling parasitic worms using E. coli expressing a dsRNA (SEQ ID NO: 1) specific to the integrin 1 subunit (SeINT) of Paralichthys olivaceus, and a method for controlling parasitic wasp. In the present invention, there is provided a composition for controlling parasitic astringency caused by feeding, which comprises a transgenic Escherichia coli expressing a dsRNA (SEQ ID NO: 1) specific to the integrin 1 subunit (SeINT) do. The method for controlling parasitic fever of the present invention comprises the steps of: pre-treating the above-mentioned transformed E. coli with ultrasonic treatment; Feeding the pre-treated transgenic E. coli to the larvae of Paralichthys olivaceus; And treating the Bt toxin after ingestion treatment. According to the present invention, the dsRNA expressed by Escherichia coli can delay the development of the parasitic larva and lead to death, thereby effectively controlling parasitic nematodes.;
