Abstract: An insect-trapping device includes a container, a funnel element, a photo interrupter and a controller. The container is formed with an inlet and an accommodation space connected to each other. The funnel element is with light-absorbed color, placed on the inlet, and inserts into the accommodation space. The photo interrupter is located within an inner passage of the funnel element for sensing whether at least one of insects passes through the inner passage from the inlet. The controller is electrically connected to the first photo interrupter for counting the insects passing through the inner passage according to the photo interrupter.
