Problems solved by technology

Chinese patent CN201810639091 (application number) discloses the application of a special light source in trapping citrus psyllids and the citrus psyllid trap. The wavelength of the special light source is 409.9nm~511.6nm. Greatly improve the effect of trapping citrus psyllids with light; at the same time, the wavelength of the special light source is single, the pertinence is strong, the specificity of trapping citrus psyllids is strong, and the damage to other insects, especially beneficial insects, is small
Physical trapping of citrus psyllids has the problem of low killing efficiency, while chemical drug control is prone to produce pesticide residues, which affects the quality of citrus products

Abstract

The invention discloses a method for expelling wood citrus lice by ultrasonic waves, and relates to the technical field of ultrasonic application. According to the method, ultrasound equipment is arranged in a grid in a citrus orchard, and then the ultrasound equipment is automatically opened in sequence from inside to outside in the citrus orchard to carry out ultrasonic emission, with the ultrasonic frequency of each ultrasound equipment being 20kHz-10MHz, the power being 1-5kW, the single ultrasonic emission time being 1-10min, and the intermittent time being 1-15min; and ultrasonic waves are adopted to block citrus wood lice and repeat ultrasonic emission, so that the effect of long-term expelling of citrus wood lice is realized. The method has an obvious effect of expelling citrus wood lice, can reduce the detection rate of citrus wood lice in orchards by more than 90%, greatly limits the ability of wood lice to spread citrus yellow dragon disease, can effectively prevent the spread and spread of yellow dragon disease, and does not need to use chemical agents, so that the method is an ecological, environment-friendly and efficient method for expelling wood lice.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic application, and in particular relates to a method for driving away citrus psyllids by ultrasonic waves. Background technique [0002] Citrus Huanglongbing (Huanglongbing) is currently the number one devastating disease of citrus production in the world, which is caused by Phloem bacteria parasitic in the phloem of plants. Due to the serious harm and high fatality rate, and the lack of effective prevention and control methods so far, Huanglongbing is called the "cancer" of citrus. The citrus psyllid is the only natural carrier of Huanglongbing in the field. In the whole life cycle of the citrus psyllid, there are three stages: eggs, nymphs and adults. Effectively controlling the detection rate of citrus psyllid is an effective way to control citrus huanglongbing. The traditional control methods of citrus psyllid mainly include physical trapping and chemical killing. Chinese patent CN20181063...
