Bark beetle trapping device

A bark beetle trapping device belongs to the technical field of pest trapping and comprises a tank body, trapping agents capable of luring bark beetles into the tank body are arranged at the bottom of the tank body, a plurality of layers of leakage nets capable of separating other irrelevant pests are arranged in the tank body side by side, and the diameters of leakage holes in the leakage nets are sequentially reduced from top to bottom. The size of the leakage holes in the bottommost layer of leakage net is that bark beetles can pass through; a protective cover is installed over the opening of the tank body, and the diameter of the protective cover is larger than that of the opening in the top of the tank body. The utility model has the beneficial effects that the problems of falling damage of antennae, elytra and the like of the bark beetles, poor specimen integrity and the like caused by the fact that target insects such as the bark beetles are eaten by silkworms in the prior art are solved, and the integ
