An efficient
insect pest light
trapping and killing lamp with air
route missing and retention comprises a lamp cap, an
insect pest
trapping lamp, an
insect pest collecting shell, a base plate, an
insect pest killing electrified wire netting ring and connecting pillars. A closed box body is arranged at the lower end of the lamp cap and used for installing a
control circuit board so that it can be prevented that the
control circuit board gets wet in the rain, so that short out and overburning happen on the
control circuit board, the base plate is fixed above the
insect pest collecting shell, and a combination body of the base plate and the
insect pest collecting shell is connected with the lamp cap through the connecting pillars to form a frame, the insect pest
trapping lamp is installed between the base plate and the lower end of the lamp cap, the insect pest electrified wire netting ring is arranged between the base plate and the lower end face of the lamp cap, and the insect pest trapping lamp is located in the insect pest killing electrified wire netting ring which is of a multi-layer spaced distribution structure for enclosing the insect pest trapping lamp. The number of distributed
layers is larger than or equal to two, and the distance between every two adjacent positive and negative
electrode wires in an insect pest electrified wire netting ring on the inner layer is smaller than that between every two adjacent positive and negative
electrode wires in an insect pest electrified wire netting ring on the outer layer. Targeted light-trapping electrified wire netting killing can be performed according to the type of preset insect pests to be killed, so that the performance of gathering the insect pests is good, and the range of insect pest individuals to be killed is wide.
