Description

Technical Field

[0001] The invention relates to the field of agricultural pest control, in particular to a device for trapping and killing two-spotted leaf beetles in fields around the clock. Background Art

[0002] Bispotted leaf beetle Monolepta hieroglyphica (Motschulsky) belongs to the order Coleoptera, family Chrysomelidae, subfamily Lupininae, genus Motschulsky. The adult has a pair of circular spots at the base of the two elytra, hence the name. Since the beginning of the 20th century, the occurrence of the two-spotted leaf beetle in northern my country has become increasingly serious, and the population has continued to grow. It has gradually become one of the important pests in corn producing areas such as Northeast China (Heilongjiang, Jilin, Liaoning, and Inner Mongolia) and Northwest China (Hebei, Shanxi, Shaanxi, and Xinjiang), and the area of ​​damage has gradually expanded. In the past two years, there have been reports of high-density population damage on summer corn in North China, and the trend has been getting worse year by year. The insect has a wide diet and prefers to feed on plants of the Gramineae, Leguminosae, and Cruciferae. It mostly occurs in July-September. When the adults just migrate from the weeds in the field to the corn field, they cause spot damage. When the damage peaks, they spread outward and migrate to adjacent farmland to cause damage.

[0003] At present, the prevention and control of two-spotted firefly leaf beetles in the field has not received due attention. The prevention and control methods are mainly based on a variety of chemical agents such as chlorantraniliprole and high-efficiency cypermethrin. However, the long-term use of chemical agents will not only pollute the ecological environment in the field, but also endanger human health, kill beneficial organisms, increase the resistance of pests, and cause the phenomenon of rampant re-emergence. In order to avoid the negative impact of chemical control, the trapping and killing control methods formulated according to the biological habits of pests have shown great advantages, such as insect traps in vegetable greenhouses to control whiteflies, aphids, leafhoppers, thrips and other pests; sex attractants are used to trap lepidopteran pests in orchards. In 2007, Li Zhigang discovered that two-spotted firefly leaf beetles like to eat corn silk and have the ability to migrate and spread over short distances; in 2021, Wang Lianxia and others found that two-spotted firefly leaf beetles have a significant tendency to yellow insect traps.

[0004] In summary, in order to avoid the negative impact of chemical control, it is currently necessary to utilize the living habits of the two-spotted firefly leaf beetle and design a device for trapping and killing the two-spotted firefly leaf beetle around the clock. Summary of the invention
