Embodiment 1

[0038] A "lure-infect-release" device, the schematic diagram of which is shown in figure 1 As shown, components such as a solar panel 1, an automatic powder spraying device 2, an insect trap lamp tube 3, a storage battery 5 and a support 6 are included. Solar panel 1 is fixed on support 6 tops, and support 6 tops hangs automatic powder spraying device 2, and insect trap lamp tube 3 is installed in the center directly below automatic powder spraying device 2. Dust spraying aerosol is installed in the automatic powder spraying device 2, and the powder spraying aerosol is convenient to change, and content is the particle powder and the propellant containing microbial insecticide 4.

[0039] The generating power of the solar panel 1 is not less than 25 watts, and the storage battery 5 guarantees that the device can operate normally under continuous cloudy weather conditions for 3 days.

[0040] The power of the insect trap lamp 3 is not less than 8 watts, and the opening time is ...

Embodiment 2

[0046] The control of embodiment 2 paddy rice planthopper

[0047] Rice planthopper, a common name for pests of the insect class Homoptera (Homoptera) Planthopper family (Delphacidae), which damage rice and other crops by piercing and sucking plant sap, including brown planthopper (Nilaparvata lugens), white-backed planthopper (Sogatella furcifera) and gray planthopper (Laodelphax striatellus) and others. Rice planthopper is an important pest of rice in China, and it has occurred continuously in various places in recent years. In the initial stage of rice damage, many irregular brown spots appeared on the stalks. When the damage was serious, the whole plant would wither and expand into pieces, causing the whole field of rice plants to fall and wither, severely reducing yield, and posing a serious threat to rice production.

[0048] Methamidophos, an insecticide widely used in the control of rice planthoppers, has been banned in China since January 1, 2007, due to its high tox...

Abstract

The invention discloses a method and a device for microbial pest control based on light luring. The method for microbial pest control based on light luring includes the steps: luring and gathering target pests by a light source or frequency spectrum waves; applying entomopathogenic microorganisms with selective toxicity to the target pests at fixed points; enabling the target pests to carry the entomopathogenic microorganisms. The device for microbial pest control comprises a solar panel, an automatic powder sprayer, a trap lamp tube, a storage battery and a support, wherein the solar panel is fixed to the top end of the support, the automatic powder sprayer is suspended at the top end of the support, and the trap lamp tube is mounted at the center under the automatic powder sprayer. Powder spraying aerosol is mounted in the automatic powder sprayer and contains propellants and particle powder containing microbial pesticides. Light luring and microbial control are cooperatively applied, control area is enlarged by the aid of migratory flight of the pests, and influence on beneficial insects is reduced as the entomopathogenic microorganisms with the selective toxicity are applied according to the target pests.

Description

technical field [0001] The invention belongs to the field of pest control, and in particular relates to a method and device for preventing and controlling pests by microorganisms based on light lures. Background technique [0002] Light insecticidal technology is a technology that uses the phototaxis of insects to attract and kill pests, thereby preventing and controlling agricultural and forestry pests and sanitary pests. Different types of insects have different sensitivities to different bands of spectrum. The long-wave ultraviolet light with a wavelength of 320-400nm, which is invisible to humans, has a strong attracting power to hundreds of pests. Generally, the light source with a wavelength of 320-680nm and a spectral range covering long-wave ultraviolet light and visible light is called a broad-spectrum insect-attracting light source. The effective range of light traps is the circular area formed by the radius of the pests’ visible light source. The effective range ...
