Beet armyworm (Spodoptera exigua Hubner) belongs to Lepidoptera and Spodoptera, is a worldwide intractable pest, has many generations of generation, fast feeding and hybrid propagation and heavy harm, has over 100 host plants, and is also favored to eat various vegetables and Chinese medicinal materials besides small coarse cereals such as soybean, corn and the like. The yield loss of the soybean damaged by beet armyworm is generally 20-30 percent and can reach more than 80 percent at most, and the healthy development of the soybean industry is seriously influenced.
In recent years, due to the influence of trade barriers, the domestic soybean demand is increasing, so that the soybean planting area in China is also increasing year by year, and the occurrence of asparagus caterpillars is aggravated year by year. In recent years, the hazard occurrence of the asparagus caterpillars in the cities is on the rise, the occurrence area is enlarged year by year, the hazard area reaches 2.6 ten thousand mu and accounts for 81 percent of the planting area of the soybeans, and generally, one hundred plants in a plot have 130-240 heads of the asparagus caterpillars and more than 500 heads of the serious plot. Because of the increase of pest resistance and serious environmental pollution caused by long-term dependence on chemical control, and because of the shortage of rural labor force, the flourishing growth of plants in the middle and later periods of soybeans, the failure of chemical agent spray control to achieve expected effects and the like, the yield of soybeans is reduced to different degrees, the beet armyworm control is always the key and difficult point of plant protection work, the economic loss caused each year is huge, the traditional control mode adopts chemical pesticides, not only high residual pesticides are generated, pests have the problems of drug resistance, environmental pollution and the like, but also the harm to people and livestock is far more than that.
In recent years, a new pest control technology for controlling pests by using a food attractant or a sex attractant is more and more widely applied, and compared with chemical pesticides, the technology does not generate the problems of high residue, drug resistance, environmental pollution and the like, and is safer for people and livestock. The technology not only has control effect on beet armyworm, but also has trapping and killing effect on various lepidoptera, coleopteran and orthopteran pests such as prodenia litura, cotton bollworm, cabbage armyworm, chafer, mole cricket and the like. The technology relies on the omnibearing three-dimensional coverage of smell in the air, and overcomes the defect that blind areas exist when chemical prevention and control are not timely performed. However, the control effect of the pests can be greatly improved by using the food attractant and the sex attractant to cooperatively control the asparagus caterpillars in the soybean field, and the technology is not reported yet.
