Method for controlling pests through purple light and converted light thereof

Abstract

The invention relates to the field of pest control, in particular to a method for controlling pests through purple light and converted light thereof. The method comprises the steps that first emittedlight and second converted light are adopted for conducting illumination treatment on a pest occurrence place, and the first emitted light comprises emitted light with the peak wavelength ranging from310 nanometers to 400 nanometers; the second converted light is obtained by excitation of the first emitted light with light intensity of at least 5%; and the second converted light includes at leastone of the following: converted light with the peak wavelength of 500 nanometers to 570 nanometers and a full width at half maximum of not more than 40 nanometers, converted light with the peak wavelength of 560 nanometers to 590 nanometers and a full width at half maximum of not more than 40 nanometers, and converted light with the peak wavelength of 400 nanometers to 490 nanometers, and the full width at half maximum of not more than 40 nanometers. By applying the method, accurate pest prevention and control can be achieved, pests can be effectively prevented and controlled, and ecologicalbalance cannot be damaged; and operation is simple, and large-scale popularization is facilitated.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a method for controlling pests through purple light and its converted light. Background technique [0002] Pest control is of great value in agriculture as well as in other fields such as industry. Insects use the optic organ as an organ to perceive light stimulation, which makes insects show sensitivity to different light spectra. The ommatidia or ocelli of insects contain visual cells that are sensitive to a specific range of spectra. There are transmembrane opsins and chromophores on the cell membranes of visual cells, which constitute photosensitive pigments. The spectral absorption of photosensitive chromatograms largely determines Spectral sensitivity of photoreceptor cells. Pest control can be achieved by utilizing the sensitivity of insects to a specific range of light spectrum. Generally, the main light sources used to control pests can be divided into two categories: one ...

Problems solved by technology

However, it is difficult for a single light source to produce a good trapping effect on various insects at the same time.

However, the combined application of LED devices of different single-primary colors to obtain light of different wavelengths, due to their different operating voltages and operating currents, the drivers required for LED lights based on different single-primary colors are also different, making the control circuit of the lighting system The structure is complex, which puts forward higher technical requirements for intelligent control technology; and the cost combination of different primary color LED devices is very expensive, which is not suitable for large-scale promotion and use
