Abstract: A method for producing a cell extract having agricultural pest insecticidal capacity by culturing filamentous fungi having insecticidal capacity for an agricultural pest, and a method for insecticide produced by this production method. A method for producing a cell extract having agricultural pest insecticidal capacity provided with a step for culturing filamentous fungi in solid medium and obtaining a solid culture of the filamentous fungi, a step for culturing the filamentous fungi in liquid medium and obtaining a liquid culture of the filamentous fungi, a step for separating mycelia of the filamentous fungi from the liquid culture of the filamentous fungi, a step for mixing the liquid culture from which the mycelia have been removed and the solid culture and obtaining a mixed culture, and a step for extracting a spore solution of the filamentous fungi from this mixed culture.
