Problems solved by technology

Compared with direct feeding hazards, citrus psyllids, as an important vector of citrus Huanglongbing, have caused greater losses to the citrus industry
[0004] Citrus psyllids have strong phototaxis and chromotropic behavior. At present, yellow boards are used to trap citrus psyllids to some extent, but yellow boards can only be used during the day, and yellow boards have no trapping effect on citrus psyllids at night.
At present, there are few studies on the prevention and treatment of citrus psyllids with light trapping technology, the trapping rate is poor, and the specificity is not good. The effect of trapping citrus psyllids with lights is not obvious

Embodiment 1

[0035] Example 1 Detection of the positive and negative phototaxis behavior of adults of citrus psyllids to light sources of different wavelengths

[0036] 1. Experimental materials

[0037] (1) Source of tested insects: Adult citrus psyllids were obtained from the Entomology Department of South China Agricultural University. They were bred on Gourilla japonica. The breeding temperature was 26±1ºC and the relative humidity was 60±5%.

[0038] (2) Light sources for testing: 9 kinds of wavelengths: 365.0±10nm, 419.9±10nm, 434.7±10nm, 459.2±10nm, 501.6±10nm, 610.6±10nm, 691.5±10nm, 729.0±10nm, 780.0±10nm Provided by Hunan Benye Green Prevention and Control Technology Co., Ltd.

[0039] (3) Testing device: The structural schematic diagram of the testing device is as follows: figure 1 shown. The detection device is Y-shaped, wherein 1, 4, and 7 are black non-reflective sponge plugs; 2 is a negative phototaxis reaction chamber made of quartz glass, cylindrical, with an outer diam...

Embodiment 2

[0070] The citrus psyllids were trapped with traps whose wavelengths of light sources were 419.9±10nm, 459.2±10nm and 501.6±10nm respectively. The schematic diagram of the trap is as figure 2 with image 3 mentioned. in, figure 2 main view, image 3 for side view.

[0071] The trap uses light of a single wavelength as a light source, wherein the wavelength of the light source of trap 1 is 419.9nm±10nm, the wavelength of light source of trap 2 is 459.2nm±10nm, and the wavelength of light source of trap 3 is 501.6nm±10nm.

[0072] The trap includes a light source 18, a hook 11, a solar panel 12, a power supply and a timing device 13, an adhesive yellow plate 17, a waterproof baffle 14, a color plate support 15 and a draw-in slot 16. Wherein, the waterproof baffle 14 is installed on the top of the swatch support 15, and is used to protect the light source 18 (because the power supply and the timing device 13 are arranged inside the waterproof baffle 14, they are not marked...

Abstract

The invention discloses application of a special light source in the aspect of diaphorina citri trapping and a diaphorina citri trapper. The wavelength of the special light source is 409.9-511.6 nanometers. Light of different wavelengths has different trapping rates for diaphorina citri trapping, the diaphorina citri has the high response index and the positive phototaxis index for the light source with the wavelength being 409.9-469.2 nanometers or 491.6-511.6 nanometers. When the light source of the wavelength is adopted, the effect of trapping diaphorina citri through lamplight can be greatly improved; meanwhile, the wavelength of the special light source is single, the pertinence is high, the diaphorina citri trapping specificity is high, and damage caused to other insects, particularly beneficial insects is small. The light source of the specific wavelength is adopted for trapping diaphorina citri, the effect of trapper lamplight trapping can be remarkably improved, the diaphorinacitri prevention effect of the trapper is improved, the consumption of chemical pesticide is lowered, pesticide residues on diaphorina citri are reduced, generation of chemical pesticide resistance of diaphorina citri is delayed, and contaminations of chemical pesticide to the environment are reduced.

Description

technical field [0001] The invention relates to the technical field of preventing and controlling citrus psyllid adults, and more particularly relates to the application of a special light source in trapping citrus psyllids and a citrus psyllid trap. Background technique [0002] Light trapping technology is a physical control method that uses the behavior of insects to move toward or away from the light source to encourage insects to gather at a fixed location for centralized elimination. At present, there are many studies on the phototaxis behavior of insects, but the phototaxis behavior of insects is affected by many aspects, and the phototaxis behavior includes positive phototaxis and negative phototaxis, and negative phototaxis is often ignored by people. In addition, the phototaxis behavior of insects also lacks a unified standard. [0003] Citrus psyllids belong to Hemiptera Psyllidae, and are important pests on Rutaceae plants such as citrus, lemon, yellow bark, and...
