The invention provides an Eucryptorrhynchus chinenis ground capture device and method; the device comprises a mesh covering the basal part of an ailanthus tree, and male and female sticking buckles tightly attached to the basal part of the trunk; the four edges of the mesh are respectively wrapped by 100-mesh nylon gauze; a middle point connecting line of two parallel edges of the mesh is provided with an opening; two sides of the opening are respectively wrapped by 100-mesh nylon gauze; the male and female sticking buckles are respectively sewed on the 100-mesh nylon gauze of the two edges of the opening after being wrapped. The device is simple in making technology, convenient in operation, low in cost, ling in life, cannot affect normal growth of the ailanthus tree, and cannot pollute environment; Eucryptorrhynchus chinenis overwintering imago and eclosion imago will unearth and climb tree so as to damage ailanthus tree branches; the device and method can keep capturing Eucryptorrhynchus chinenis overwintering imago and eclosion imago in long time, so the Eucryptorrhynchus chinenis overwintering imago and eclosion imago cannot harm the tree and mate and lay eggs; the device and method have good capturing effect for underground pests like Chinese mole cricket, chafer imago and larva.
