Description

Attraction killing device for farmland lepidoptera pest corn borer larva attractant

Technical Field

The invention relates to the technical field of attracting and killing devices, in particular to a device for attracting and killing corn borer larvae serving as lepidoptera pests in a farmland.

Background

Agriculture is an industry for obtaining products through artificial cultivation by utilizing growth and development rules of animals and plants, belongs to the first industry, the science of research 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.

In the agricultural field, crops such as flowers, vegetables, fruit often receive the insect pest, and the peasant need spray multiple pesticide sometimes and just can the deinsectization, but the overuse of pesticide has huge restriction effect to the growth of crops, and it can wither to straighten, and the use of pesticide also influences environment and personal health simultaneously, just at this moment need use the pest trapping and killing device and administer the insect pest to crop growth that can be better.

The existing Chinese patent (publication number: CN112293375A) discloses an agricultural winged insect trapping and collecting device, and aims to solve the problems that the trapping and killing device in the above patent adopts perfume to trap insects, the insects need to be replaced after a period of time, the operation is troublesome, and the insects cannot be effectively collected after being corona, so that the insects can be revived. According to the invention, the electric network can corona or electrocute flying insects, the flying insects fall into the insect collecting box, the rubber strand wires are obliquely arranged to prevent the flying insects from continuously flying upwards, the insect attractant does not need to be frequently replaced, the insects can be effectively collected after being corona, the situation that the insects can revive can not occur, and the use requirements of people are met.

Also, Chinese patent (publication No. CN110771584A) discloses an agricultural pest trapping and killing device, aiming at the problems that the height of the existing trapping and killing device is fixed, the device is inconvenient to be applied to different agricultural fields and the trapped and killed pests are inconvenient to clean, the invention proposes a scheme that the device comprises a base, the top of the base is fixedly connected with a fixed seat, a lifting device is arranged on the fixed seat, a fixed column is fixedly connected on the lifting device, and two cross bars are symmetrically and fixedly connected to one side of the fixed column. The subsequent utilization rate is convenient.

According to the two patents, the existing trapping and killing of pests in agriculture generally adopts the combination of a trap lamp and a power grid or is matched with an attractant to trap and kill the pests, flying insects can only be trapped and killed, meanwhile, the situation that the flying insects fly out after entering a collecting box easily occurs, the trapping and killing of the pests in different agricultural planting densities is difficult to adapt, and the use performance of the device is reduced.
