The author designed photoelectric self-control pest control instrument, is a circuit structure is simple, easy to weld, high sensitivity, easy to use insect trap device. The use of proof, the device pest control effect is satisfactory, high success rate. It provides instruments for eliminating phototrophic pests in agriculture and forestry with minimal labor, energy saving and manual management. The figure shows the working principle of the device circuit. The right half is black light lure pest device, the left half is the photoelectric automatic control circuit. 3DU for the phototransistor, J_1 JQX-10F-type DC relay, suction
