Trapping device for collecting crawling insects and application thereof

The invention relates to the technical field of agricultural pest trapping and killing, in particular to a trapping device for collecting crawling insects and application thereof. The trapping devicecomprises an inducing area and a trap area, the inducing area comprises an inducing pipe, and the inducing area is connected with the trap area through the inducing pipe; and trapping and killing agents are arranged in the trap area. When the trapping device for collecting the crawling insects is used, the insects enter a one-way channel when crawling to the inducing area from the inducing pipe, walk into the trap area under the attraction of the attractant and fall into a trap, and even if the insects climb to the exterior of a lower shell when making contact with an upper shell of the trap area, due to the characteristic of the inducing pipe in the inducing area, the insects can also return to the interior of the lower shell of the trap area in the non-purpose crawling process, and therefore the insects fall int
