Agriculture is an industry for obtaining products by artificial cultivation by utilizing growth and development rules of animals and plants, and belongs to the first industry, the science of researching agriculture is agriculture, the labor object of agriculture is living animals and plants, the obtained products are the animals and plants, and the agriculture is a basic industry for supporting national economic construction and development. The traditional method for preventing and controlling pests mainly utilizes chemical pesticides, has the advantages of quickly killing pests and controlling outbreak harm of pests, and has the defects of causing the generation of drug resistance of the pests due to the frequent use of the chemical pesticides, causing pesticide pollution residue on agricultural products and bringing adverse effects on human beings, livestock and ecological environment.
Corn (Zea mays L.) is one of the main food crops in China, the planting area exceeds 6 hundred million acres, the corn becomes the crop with the largest area and the largest total yield, and the corn has an important strategic position for guaranteeing the food safety in China. In China, dozens of corn pests exist, and the harm of corn borers and spodoptera frugiperda is the most prominent. The corn borer, called corn borer, belongs to the lepidoptera borer family, mainly damages stem tissues by damaging stems by larvae, influences nutrient transportation and damages plants, and when serious, the stems are broken by wind. Spodoptera frugiperda (Spodoptera frugiperda) also called fall armyworm belongs to Lepidoptera Spodoptera, invades Yunnan of China in 2019, rapidly spreads across the country, saves more than 30 pests at present, and has a pest area exceeding 409 million hectares. Spodoptera frugiperda mainly destroys growing points with larvae, bites tender tissues in boring heart leaves, has a very large food intake, forms irregular long holes on leaves, and can be eaten by the leaves of the whole corn plant when serious. The two pests seriously threaten the harvesting quality and quantity of the corn, and the use of a large amount of chemical pesticide also brings great hidden danger to the food safety.
The trap lamp is a common insect behavior regulation and control device, can be combined with measures such as an attractant, a repellent and the like to form a 'push-pull' technical strategy, is widely applied to monitoring and controlling agricultural pests, and plays an important role in pest control, prediction and forecast. The extent to which the artificial light attracts insects depends on the spectral composition of the light source. However, the most widely used trap lamps in the current market belong to multispectral broad-spectrum light, are not strong in pertinence, and can accidentally injure many natural enemy insects while trapping pests, so that ecological balance is damaged. Therefore, according to the life habits, the light sensitivity and the like of the ostrinia nubilalis and the spodoptera frugiperda, the most sensitive artificial light source wavelength of the ostrinia nubilalis and the spodoptera frugiperda is found and applied to green prevention and control of pests.
