The invention belongs to the technical field of plant protection, and discloses a method for carrying out fast non-destructive detection on fruit and tuber eating pests by using spiral CT. The methodcomprises the steps of 1, performing scanning detection on potatoes which are damaged by phthorimaea operculella but cannot be seen in surface damage by using the CT; 2, during detection, independently placing the potatoes or storing the potatoes in a box; 3, reconstructing a volume image after scanning; and 4, recombining axial, coronal, sagittal and VR images by utilizing the volume image so asto meet the diagnosis requirement. According to the method, under the condition that fruits and tubers are not damaged, whether the interiors of the fruits and the tubers are damaged by the fruit eating pests or the phthorimaea operculella or not can be rapidly detected at one time; the conditions of the surfaces and the interiors of the fruits and the potato tubers can be observed rapidly througha CT post-processing techn
