The invention discloses a method for selectively trapping and killing pests by using a monochromatic LED (Light-Emitting Diode) lamp, belonging to the field of equipment for destroying harmful animals or plants. The pests of designated species are trapped and killed or driven by using the LED lamp capable of emitting a specified/designated wavelength through the singleness of the spectral wavelength of an LED light-emitting device, wherein the LED lamp is a combined/composite type light source consisting of a plurality of LED light-emitting devices. Because the light source only emits a monochromatic light of a certain specified/designated wavelength or a combined monochromatic light of several specified/designated wavelengths, the light source has attractability to only a certain species or several species of pests and the broad spectrum attractability to various species of pests in the prior art can be avoided. The currently epidemic pests are pertinently killed by using the LED lamp with the monochromatic light of different wavelengths or the monochromatic light combination, and the LED lamp is a real ecological-type trap lamp. The invention can be widely applied to the field of catching or killing or dissipating the harmful insects in agriculture and forestry.

The present invention is a method of controlling noxious plant species. The method comprises identifying a target area in a foraging area, selecting a treatment period, selecting an ungulate specie, providing an animal feed supplement at a first deployment location in the target area, and introducing the selected ungulate specie to the animal feed supplement in the target area during the treatment period. The target is considered such because it includes a noxious plant specie. During the treatment period, the selected ungulate specie will interact with the noxious plant specie in the target area. For example, the ungulates interact with the noxious plant specie by eating the noxious plant specie and/or by trampling the noxious plant specie. The animal feed supplement is highly-palatable, portable, self-limiting, attracts the ungulate specie to the target area, and increases the length of stay of the ungulate specie in the target area.
