Description
Technical Field
The invention relates to the technical field of agricultural pest trapping and killing, in particular to a reusable pest trapping plate and application thereof.
Background
Important small pests in agricultural production in China, such as thrips, whiteflies, aphids, liriomyza and the like, cause serious damage to the production of vegetables, flowers and greenhouse crops every year. The traditional method for preventing and controlling pests in China is chemical prevention and control, modern green pest prevention and control measures are increasingly popularized along with the upgrading of agricultural production technology, and the pest sticking plate manufactured by utilizing the chromotropic property of the pests is convenient to use, intuitive in trapping effect and easy to operate, is gradually popularized and applied to production bases such as greenhouses, orchards, nurseries and the like, and becomes an important prevention and control material for physical prevention and control measures, forecast and early warning in comprehensive pest control.
The traditional insect-attracting colored plate mostly adopts PP plastic as a base plate, two surface layers are uniformly coated with insect-sticking glue, and the surface of the glue is covered with a layer of protective film. When in use, the insect-attracting color plate is hung in a designated place, and the surface protective film is uncovered for attracting insects. The insect-attracting colored plate made of novel degradable materials is mainly made of degradable plastics containing corn starch or cellulose acetate, some photolysis catalytic substances are added sometimes, although the degradable insect-attracting colored plate is environment-friendly, the problems of harsh storage conditions, poor stability in practical application and the like exist, even if the substrate can be degraded, the commonly used insect-sticking glue layer substances are acrylate monomer copolymers and are also substances which are difficult to decompose.
Generally, pests such as aphids and whiteflies have a yellow tendency, thrips has a strong tendency to blue, leafhoppers have a strong tendency to green, and insect attracting plates for different pests can be manufactured by utilizing the color tendency of various pests. And the attractant for attracting insects is coated on the panel or the slow-release rubber plug is hung on the panel, so that the attracting efficiency of the target pests can be increased. When the number of the pests is dynamically monitored through the pest trapping colored plate, the pest trapping plate generally needs to be replaced after investigation and counting every time, and the pest trapping colored plate can be hung until the pest trapping plate is not sticky when being only used for physical prevention and control.
However, after the traditional insect attracting colored plate is used for a period of time, the insect sticking glue is gradually dried, or the adhesive is lost due to sticking of insect bodies and dust, so that the insect sticking colored plate cannot be used continuously, and at the moment, the service life of the insect sticking colored plate is finished, and the insect sticking colored plate cannot be reused. Moreover, there are also the following drawbacks and problems that need to be solved: 1) generally, the discarded insect attracting plates can only be discarded as agricultural wastes, so that a lot of plastic wastes are generated after each production stage, and the insect attracting plates are a burden for users. 2) When the protection film was torn in the use to the board that lures of glue coat, operating personnel touched the glue film of look board easily, influenced the local mythimna separata effect of luring the board on the one hand, is stained with the inconvenient other farming operations of cull on the other hand operating personnel's hand or the gloves, also is difficult for clearing up. 3) When the traditional insect-attracting color plate is used for observing insect experiments, errors in experimental data observation can be increased due to frequent replacement of the color plate. 4) The traditional insect-attracting colored plate is easy to cause the problems of colloid gummosis, difficult separation of protective films and the like during storage and use. 5) The traditional insect attracting color plate is disposable, and can not be normally used and only be discarded if the traditional insect attracting color plate carelessly falls off the ground in the operation process.
