Push-pull technology for controlling pests through light

Abstract

The invention relates to a push-pull technology for controlling pests through light. In the same biological system, pest expelling lamps are installed in a center area, and expel pests to move towards the edge of the system. Trap lamps are installed on the edge of the biological system, and the pests expelled to the edge of the biological system are trapped. The wavelength of the pest expelling lamps is suitable for repelling pests, and the wavelength of the trap lamps is suitable for trapping the pests. According to the push-pull technology, the pest expelling lamps and the trap lamps with different numbers are installed according to the size of the area of the biological system, the distance between the pest expelling lamps, the distance between the trap lamps and the distance between the pest expelling lamps and the trap lamps are 100-150 m, 150-250 m and 250-500 m respectively. For a large-area biological system, multiple rows of pest expelling lamps and trap lamps can be alternately installed. The wavelength of the pest expelling lamps is 500-600 nm, and the expelling performance on Lepidoptera moth pests is high; the wavelength of the trap lamps is 350-390 nm, and only moth pests can be expelled. The push-pull technology can be used for protecting natural enemy insects of coleopteran, hymenoptera, neuroptera and the like and some neutral insects.

Description

technical field [0001] The invention relates to a push-pull technology for controlling pests by using light. Background technique [0002] Developed countries in Europe and the United States have set up various barriers to the export of my country's agricultural products, and the promotion of harmless control technologies for agricultural pests is the only way for the development of my country's modern agriculture. Based on the phototaxis characteristics of insects, the use of light for pest control has the advantages of good control effect, no residue in the environment, and no resistance to pests. At present, pest light attractant technology has become one of the important means of agricultural and forestry pest control in my country. [0003] However, the pest control concepts of various types of insecticidal lamps widely promoted and applied at present are philosophy of elimination, and all insects (including natural enemy insects and neutral insects) with phototaxis ch...

AI Technical Summary

Problems solved by technology

[0003] However, the pest control concepts of various insecticidal lamps widely promoted and applied at present are the philosophy of elimination, and all insects (including natural enemy insects and neutral insects) with phototaxis are lured and wiped out.

On the one hand, this control strategy is not conducive to the protection of biodiversity and the maintenance of ecological balance; on the other hand, it will greatly reduce the role and status of light trapping technology

In practical applications, "insect nests" under the insecticidal lamp often appear, that is, the pests that have been attracted by the insecticidal lamp but have not been put on the lamp, remain on the crops around the lamp, and concentrate on laying eggs, resulting in the number of insect populations under the lamp increased and more dangerous

In addition, the light radiation area is limited, and the pests far away from the light area will not rush to the light because they cannot receive the stimulation of light, which reduces the trapping and killing effect of the light.

All in all, the single insect trap technology currently used in our country still has some shortcomings in terms of application range and effect.
