The invention provides an entomopathogenic fungus conidium collection process. An entomopathogenic fungus strain is inoculated into Sabouraud liquid medium and cultured, so that an entomopathogenic fungus liquid strain is obtained; the liquid strain is then inoculated into rice medium or bran medium and cultured until spore production are mature; after being mixed, the medium containing the mature spore production and vegetable oil or mineral oil are uniformly stirred under the process temperature of 3 DEG C to 30 DEG C, so that a dispersed system is obtained; the dispersed system is put onto a 120mu m to 150mu m screen and filtered, after obtained filtrate is dewatered under vacuum condition and then centrifugally filtered or filtered by screening, conidium ointment is collected. The conidium ointment which is collected by the screening process combined with stirring under the specific temperature (3 DEG C to 30 DEG C) not only can prevent conidia from being damped, but also can be directly used for preparing pesticide products, such as powder and suspension.
