[0002] Forestry refers to the production department of protecting the ecological environment and maintaining the ecological balance, cultivating and protecting forests to obtain wood and other forest products, and utilizing the natural characteristics of trees to play a protective role, and is one of the important components of the national economy. Forestry includes afforestation, forest cultivation, forest protection, forest felling and renewal, and collection and processing of wood and other forest products. In the long process of human social development, people's understanding of forests has undergone a long exploration process. How to handle the relationship between cultivating, protecting and utilizing forests runs through the whole process of forestry development.

[0003] Forest pests refer to species, strains or biological types of plants, animals or pathogens that can cause harm to forest plants and their products, affect their growth, survival, use and ornamental value, including diseases, insects, rodents (rabbits) and harmful plants. For example, the American white moth, the pine caterpillar, and the pine nematode disease.

[0004] At present, due to the need for greening the environment, the forest area is expanding, but the ecological environment is fragile, the forest quality is poor, and the artificial forest is large, which provides host plants for the reproduction of forest pests and provides objective conditions for their breeding and spread. Moreover, there are many types of forest pests, and the diversity of forest pests and the complexity of environmental conditions, combined with other factors, have made the occurrence and harm of forest pests more and more serious. It is called the smokeless forest fire and has become one of the important factors affecting ecological construction. Many areas have become multiple and outbreak areas of forest pests, which has a great impact on local forestry production and ecological environment, and the economic losses are also more and more serious.

[0037] A slide cylinder 107 is detachably arranged in the shell 102, a movable end of the slide cylinder 107 is connected with a transparent baffle 108, the transparent baffle 108 is in sliding fit with the shell 102, two end faces of the shell 102 are provided with pest inlets 109, the transparent baffle 108 can reciprocate on the inner surface of the shell 102 through the slide cylinder 107 to shield or open the pest inlets 109; a pest lamp set is arranged on each of the left shell 105 and the right shell 106, the pest lamp set is used for attracting pests into the insect catching net bag 101; a mounting groove 110 is arranged on the mounting plate 104, a sensor 111 is mounted in the mounting groove 110, the sensor 111 is connected with the slide cylinder 107 through a controller, and the sensor 111 is used for detecting whether there is a pest above the transparent baffle 108;

[0038] In actual use, the fixed ring assembly is installed on a tree in a forest, and then the induction lamp group is turned on. As an embodiment, the sensor 111 is an ultrasonic distance sensor (hereinafter referred to as "sensor" for short); the initial position of the pest entrance 109 is in a closed state. Then the preset values on the sensor 111 are adjusted, and preset value A and preset value B are set first. The size of preset value A is set according to D1; the distance D1 is the distance between the transparent baffle 108 and the sensor 111; the size of preset value B is set according to the distance D2, and the distance D2 is D1+2cm; when the value on the sensor 111 is less than A or greater than B, the transparent baffle 108 is in a closed state; when the value on the sensor 111 is between A and B, the transparent baffle 108 is in an open state.
