[0001] The present invention relates to the technical field of pest monitoring, and in particular to a device and method for monitoring pests in urban landscape gardens. Background Art

[0002] At present, in urban landscape gardening, in order to protect the ecological environment of the garden, it is necessary to monitor pests so that pests can be eliminated in time and the damage to urban landscape gardening can be reduced. However, when traditional pest monitoring devices are used for monitoring in dark corners or at night, the monitoring effect is greatly reduced due to insufficient light, which is very inconvenient.

[0003] In the prior art, a support pole is provided, and a light-emitting unit is installed on the support pole. The light-emitting unit is an insect-attracting lamp, and the pests can be gathered by utilizing their phototaxis, and then monitored by a camera.

[0004] However, in the aforementioned prior art, when pests gather outside the insect-attracting light, the camera will be blocked because it is close to the insect-attracting light. At the same time, a large number of pests gather and produce feces and secretions, which will stain the camera, reduce the camera clarity, and thus affect the monitoring accuracy. Summary of the invention

[0005] The purpose of the present invention is to provide an urban landscape garden pest monitoring device and method to solve the problem in the prior art that when pests gather outside an insect-attracting lamp, the camera will be blocked because the camera is close to the insect-attracting lamp.
