Environmentally friendly and energy-saving injurious insect trapping device

The invention discloses an environmentally friendly and energy-saving injurious insect trapping device. The environmentally friendly and energy-saving injurious insect trapping device comprises a trapping device main body and an insect trapping lamp, wherein the insect trapping lamp is arranged on the lower portion of the trapping device main body; a sealing end cap and sex attractants are arranged on the upper portion of the trapping device main body; the sealing end cap is provided with a storage battery; and an inner-layer net cover is arranged in the trapping device main body and is provided with a one-way inlet. By the insect trapping lamp, the problem that injurious insects attracted by the sex attractants are single in type is solved; and after entering a collecting space, the injurious insects cannot escape from the one-way inlet, so that the environment cannot be polluted, and the device is safe for people and animals. The injurious insect trapping device has regular and long-lasting effect on populations of the injurious insects, and solar panels provide required electric energy for the device. The trapping device can be reused, and has the advantages of energy conservation, environmental protection, high efficiency, sanitation, safety, easiness and convenience in operation, zero later-stage maintenance and the like.
