Problems solved by technology

However, because these light sources have a wide range of wavelengths and are not highly targeted, they are easy to accidentally kill some natural enemies and a large number of neutral insects in the field and adjacent areas, causing some impact on local biodiversity.

Embodiment 1

[0013] 1. Test material

[0014] Source of tested insects: The initial population of adult citrus psyllids was collected from Sun Yat-Sen University. They were raised in the insect culture room with Murata citrus, and the progeny populations were used as experimental insects.

[0015] Plants to be tested: Biennial Shatangju

[0016] The test light source: the same frequency (12V8W), the wavelength is 320, 340, 351, 360, 368nm, 380, 400, 420, 445, 460, 480, 525, 545, 560, 575nm and 580nm, a total of 16 LED fluorescent lamps, Provided by Shenzhen Fuweisheng Technology Co., Ltd.

[0017] 2 test method

[0018] 2.1 Selection of the best light source for attracting citrus psyllid adults

[0019] In one size 36m 2 In the self-built light-proof tent, place a pot of sugar orange in the middle, and place six LED lampshades at a distance of 2.5 meters from the sugar orange. effect. Select 6 LED lights for each group of experiments, and install them on each lampshade in order of wa...

Embodiment 2

[0045] Such as figure 1 As shown, the combined light source of this embodiment has a good trapping effect on citrus psyllid adults, which includes an LED lamp driving power supply 1 and an LED lamp connected to the LED lamp driving power supply. The LED lamp includes two kinds of LED lamps, One is an LED lamp 21 that can generate light with a wavelength of 340nm, and the other is an LED lamp 22 that can generate light with a wavelength of 545nm. All the LED lamps are installed on the LED lamp panel 2 .

Embodiment 3

[0047] Such as figure 2 As shown, the combined light source of this embodiment has a good trapping effect on citrus psyllid adults, which includes an LED lamp driving power supply 1, an LED lamp connected to the LED lamp driving power supply and a dimming device 3, and the LED lamp includes Two kinds of LED lamps, one is the LED lamp 21 that can produce light with a wavelength of 340nm, and the other is an LED lamp 22 that can produce light with a wavelength of 545nm. All the LED lamps are installed on the LED lamp panel 2. The dimming The device 3 is connected with the LED lamp to control the light intensity of the LED lamp.

Abstract

The invention discloses a combination light source with a good trapping effect for citrus psylla adults. The combination light source at least comprises an LED lamp drive power source and two kinds of LED lamps connected with the LED lamp drive power source, wherein one kind of LED lamps can generate light with the wave length of 340 nm; the other kind of LED lamps can generate light with the wave length of 545 nm. The combination light source is composed of the two kinds of LED lamps capable of generating light with the wave length of 340 nm and 545 nm. Experiments show that the combination light source has the good trapping effect for citrus psylla adults; compared with single light with the wave length of 340 nm and single light with the wave length of 545 nm, the trapping effect is better, and the effect improving function is achieved.

Description

Technical field: [0001] The invention belongs to the field of physical control of insects, and in particular relates to a combined light source which has a good trapping effect on adult citrus psyllids. Background technique: [0002] As a devastating disease on citrus, huanglongbing (huanglongbing) has caused great economic losses to the world's citrus industry. Citrus psyllid (Diaphorina citri) is the vector insect of Huanglongbing. It can produce multiple generations in one year and has strong reproductive ability. In the Qing Dynasty, strict control of citrus psyllids in large areas is still a key measure for the prevention and control of Huanglongbing. At present, the control methods of citrus psyllid mainly rely on chemical control, which is not effective. Extensive use of chemical pesticides not only pollutes the environment, endangers human health, but also leads to insect resistance. [0003] Taking advantage of the phototaxis of insects, designing insect traps to ...
