At the peak of the pests, the litchi and longan gardens in Guangxi, at the dark, a ray of vibrating insecticidal lamps in the field. A single lamp can trap more than 40,000 insects a day, reducing the amount of pesticides used, which is environmentally friendly and safe. Qiu Shibang, an academician of the Chinese Academy of Sciences who has been engaged in biological pest control for a lifetime, commented that the frequency-vibration insecticidal lamp traps pests and is an important advance in the technology of light control.
Recently, at a live meeting in Guilin, Guangxi, experts and scholars from home and abroad observed it as the "world's first physical insecticide". According to Dr. Xia Jingyuan, director of the National Agricultural Technology Promotion Center, the frequency-vibration insecticidal lamp traps the pests by using the frequency-induced trapping technology of the electric trapping principle, applying the wave vibration technology, and the light and waves emitted by the frequency-vibration insecticidal lamp. They are set in specific ranges to increase the types of pests that are trapped. It uses light at close range, waves at long distances, and high voltage around the lights to hit the grid to knock down the "fire" pests. In this way, the trapping effect can be greatly improved.
Traditional techniques such as black light have long been used to trap insects, but the trapping effect is not good enough to be widely promoted. In contrast, the use of frequency-vibration insecticidal lamps to trap pests, the average control effect is more than 70%, can be trapped and killed by 13 orders of 67 families of pests. Due to the special light wave technology, it will not trap natural enemies and be safe for humans and animals.
According to reports, the amount of insect trapping of the frequency-vibration insecticidal lamp varies from time to time and from place to place. Scientists and technicians have found that some insects have obvious peaks of light. Coleoptera and Lepidoptera are mainly in the middle of the night, and the insects of the Noctuidae are more in the middle of the night. The height of the hanging lamp is preferably 30-50 cm from the top of the crop. The vegetable pests have a higher light-emitting rate for lamps that are 100-120 cm above the ground. The effect of the wind and the light is not good. There are no insects in the rain, and the number of insects in the air before and after the rain increases significantly.
