Description
Technical Field
The invention belongs to the technical field of microwave application, and particularly relates to a method for killing diaphorina citri nymphs by microwaves based on a ground self-propelled wheel type machine.
Background
Citrus Huanglongbing (huangglongbing) is the first devastating disease of current global citrus production, caused by the parasitizing brevibacterium within the phloem of plants. Due to the serious hazards and high mortality, and the lack of effective prevention and control methods to date, huanglongbing is known as citrus "cancer".
The diaphorina citri is the only natural transmission medium of the diaphorina citri in the field, the whole life cycle of the diaphorina citri comprises three stages of eggs, nymphs and adults, the adults and the nymphs suck the primary peel juice in a large amount to obtain and transmit the diaphorina citri, and timely and effectively controlling the population quantity of the diaphorina citri is an effective way for preventing and treating the diaphorina citri. The traditional method for controlling the diaphorina citri mainly comprises two methods of physical trapping and chemical killing. Chinese patent CN201810639091 (application number) discloses application of a special light source in trapping citrus psyllids and a citrus psyllid trap, wherein the wavelength of the special light source is 409.9 nm-511.6 nm, and when the light source with the wavelength is used, the effect of trapping the citrus psyllids by lamplight can be greatly improved; meanwhile, the special light source has single wavelength and strong pertinence, has strong specificity for trapping diaphorina citri, and has small harm to other insects, particularly beneficial insects. Chinese patent CN201810370904 (application number) discloses a diaphorina citri control device and method, which comprises a spawning mechanism and a light trapping mechanism, wherein the spawning mechanism comprises a supporting body, the supporting body comprises a root, a side surface of the root is connected with a supporting blade, the length of the supporting body is L, and L is more than 0 and less than 10 mm. The other side surface of the root part is connected with a bearing installation part. The light trapping mechanism is provided with an ultraviolet lamp, and the wavelength range of the ultraviolet light generated by the ultraviolet lamp is 390nm-405 nm. Chinese patent CN201810428158 (application number) discloses an insecticidal composition suitable for preventing and controlling diaphorina citri by drip irrigation, the active ingredients of the insecticidal composition are binary complex formulation of sulfoxaflor and cyantraniliprole, and the optimal synergistic ratio of indoor bioassay of the insecticidal composition to the diaphorina citri is 5: 3. Chinese patent CN201510931478 discloses a pharmaceutical composition for controlling diaphorina citri. The drug comprises acetamiprid and rotenone, wherein the mixing volume ratio of the acetamiprid to the rotenone is 5-15: 1. the problem of low trapping efficiency when the citrus psyllids are physically trapped, and pesticide residues are easily generated in chemical drug control, so that the product quality of citrus is influenced. Therefore, the development of a novel method for controlling diaphorina citri is urgently needed.
The microwave is a short for a limited frequency band in radio waves, and refers to electromagnetic waves with the frequency of 300 MHz-300 GHz, namely the wavelength of 1 mm-1 m. The microwave irradiation has the advantages of short time, fast temperature rise, high efficiency, energy conservation, safety, environmental protection, sensitive reaction, simple equipment, convenient control and the like, and is a novel physical sterilization and disinsection technology. The advantages of microwaves derive from the thermal and non-thermal effects of microwaves. In the microwave sterilization and disinsection process, bacteria or pests are always in the microwave electromagnetic environment and are subjected to the action of two fields, namely a temperature field and an electromagnetic field, created by the microwave electromagnetic field. When the microwave penetrates through a medium due to the high-frequency characteristic of the microwave, polar molecules such as water, nucleic acid, protein and the like are subjected to orientation movement under the action of an alternating electric field, and the polar molecules rub against each other to generate heat, so that the temperature is increased, and molecules such as nucleic acid, protein and the like in a microorganism body are denatured and inactivated, thereby achieving the effect of killing pathogenic microorganisms and pests.

Chinese patent CN201810362098.3 (application number) provides a method for killing or killing tea leafhoppers in a tea garden by microwaves, comprising the following steps: step S1, arranging a support frame on a ridge of the tea garden, erecting two guide rails on the support frame, and respectively arranging two small rail cars on the two guide rails; step S2, arranging a support frame among the four small-sized railcars, arranging connecting pieces downwards around the bottom of the support frame, erecting an arc-shaped cover body at the bottom of the four connecting pieces, wherein the cross section of the arc-shaped cover body is in an inverted U shape; step S3, arranging a plurality of microwave antennas on the inner side wall of the arc-shaped cover body; a solar panel is arranged on the arc-shaped cover body, and a storage battery and a charging and discharging circuit are arranged on the supporting frame; step S4, connecting the solar panel with the charging and discharging circuit, connecting the charging and discharging circuit with the storage battery, and connecting the charging and discharging circuit with the microwave antenna and the small-sized railcar; and step S5, starting the microwave antenna, starting the small-sized rail car, enabling the small-sized rail car to slide on the guide rail to drive the supporting frame to move, covering the arc-shaped cover body on tea leaves on ridges of the tea garden, and carrying out microwave emission on tea lesser leafhoppers on the tea garden through the microwave antenna so as to carry out insecticidal operation. Microwave pest killing has been well applied in the aspect of controlling certain pests, however, no microwave killing method aiming at the diaphorina citri exists at present.
The diaphorina citri imagoes have the characteristics of bouncing movement and short-distance flight, and the diaphorina citri can escape everywhere when the diaphorina citri imagoes are killed in a movable mode in an orchard, so that the killing effect is poor. And the psylla nymphs are classified into 1-5-year nymphs, the 1-3-year nymphs hardly move, and the 4-5-year nymphs have weak crawling capability and can only crawl slowly on young tips. Therefore, the method for killing the diaphorina citri nymphs by microwaves based on the self-propelled wheel type machine is developed aiming at the characteristic that the diaphorina citri nymphs have weak mobility, the diaphorina citri nymphs can be killed efficiently and non-toxically, generation transfer of the diaphorina citri is cut off, the control of the number of the diaphorina citri populations in a citrus orchard is facilitated, and the spread of the citrus yellow shoot are controlled.
