Research Progress about prevention and control of diseases and insect pests with artificial LED light

Agriculture is the foundation of the national economy, overall, in many areas of modern agriculture, such as pest control and so on all have extremely close relations with artificial lighting. In terms of prevention and control of agricultural pests, can be used in a specific wavelength of the LED street light source, to lure and kill pests, reduce pesticide seems to do safety green production.
In cultivation, with pest to uv light, blue light is of high sensibility, to seduce, use of lamps and lanterns of high voltage power grid will be destroyed, killed pest can make good fertilizer. Main product spectrum now used for pest trapping is as follows:
Uv intensity of illumination of the higher, and draw the better the results, so the actual agricultural use of trap in the outdoor lamp basically is given priority to with high output fluorescent lamp.
Insect visual and human vision is very different, he is ultraviolet perception. In agricultural field using the technology of artificial light elimination of insect pests have lured by using light (uv) insect pests and weeds, after studying the phototaxis of insects using ultraviolet development of insect is used fluorescent lamp, suitable for relatively airtight greenhouse, plant factory. In order to reduce the peach and citrus fruit by the moth and other pests, such as Japan in the 1960 s, popular throughout the country a Huang Guangfang moth lamps and lanterns. In 2000, and to find the most time to curb the wavelength of pest activity is 540 ~ 545 nm, so which has the function of efficient control the moth moth proof lights near ideal spectral distribution should be in the range. The latest generation of moth proof technology is to use green moth proof light, little adverse impact on the plant.
In addition, in terms of artificial light induced disease resistance, in recent years, there are some practical level of practical application with artificial light and the scene of the cultivation of disease resistance induced technology is published and put into application. Now, the actual use of prevention against technology is: low plant disease resistance induced by green light irradiation technology and using ultraviolet light (UV – B) also induced plant production technology of plant disease resistance to prevent disease.
Edible fungus, besides can adjust edible fungus growth and development, the LED street light source in terms of edible fungi factory production pest control also has application prospect. Experiments show that the green, white, yellow insecticidal lamp of pests to trap effect of total is much higher than the blue and pink insecticidal lamp. Among them, green for a number of important pests showed good trapping effect.
In conclusion, based on the state of insect life, habits, plant physiological characteristics to identify the light wavelength and the action of insects, plant physiology change rule, find out relevance is very important. Artificial light prevention and control of plant diseases and insect pests can purify the environment, protect the ecological system. The future use of the new light source, new pest control technology is also worth looking forward to.
