Method for selectively trapping and killing pests by using monochromatic LED lamp

Abstract

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.

Description

technical field [0001] The invention belongs to the field of equipment for eliminating harmful animals or plants, and in particular relates to a device for catching or killing insects. Background technique [0002] At present, in agriculture, we usually mainly rely on spraying pesticides to kill pests that harm crops. This not only pollutes the air, water sources and soil, but also makes the food, vegetables and fruits eaten by people contain toxic substances of pesticides, which endangers human health and affects food safety. , It is also easy to cause pests to develop more and more drug resistance, and fall into a vicious circle. [0003] There is a pigment in the retina of phototaxis insects, which can absorb light of a certain wavelength and cause a photoresponse, stimulating the optic nerve to move towards the light source. [0004] Phototaxis is one of the important biological characteristics of many insects, which reflects the selection and adaptation of insects to e...

Problems solved by technology

[0008] However, in the prior art, whether it is a black light lamp, an ultraviolet light lamp or other types of light source insect traps, the light emitted by the light source has a certain wavelength range, in other words, it is not a monochromatic light of a single wavelength. , so in actual use, while using the insect trap lamp to kill a certain type (species) of pests, it may also kill a large number of its natural enemies (such as ladybugs (tortoise ladybug, heterochromia ladybug, seven-spot ladybug, etc.) ) and lacewings (Chinese lacewings, large lacewings, lacewings, etc.), that is, as the saying goes, "good bugs and bad bugs are killed together"; It also plays the role of "attracting" insects, and even attracts insects that did not appear in the target field. On the contrary, it makes the area around the insect trap lamp known as the "enrichment" area of ​​various insects, which completely violates the law. The original intention and intention of setting up insect trap lights
