Problems solved by technology

[0005] However, with the increase in production and application, the existing insect pheromone products in my country have exposed a large room for improvement, such as short product duration, weak release stability, and small unit radiation area, etc.
The key point of the above problems is that the slow-release carrier cannot guarantee the stable release of insect pheromones, and its own drug loading and unit release are limited.

Embodiment 1

[0047]Embodiment 1. Application of insect pheromone film-like carrier products under different environmental conditions

[0048] 1. In the paddy fields in the southern high-temperature region and the northern low-temperature region, carry out the prevention and control of the rice stem borer, and add the sex pheromone of the rice stem borer to the sub-layer pheromone of the pheromone film carrier in the preparation stage. In the storage layer, the bottom non-slow-release layer, the second slow-release film layer, and the top non-slow-release layer with holes are stacked up and down together, and the 4 layers are heat-sealed into a whole along the periphery, which is the sex information of the stem borer. Film-like carrier-oriented products;

[0049] 2. Due to the high temperature in the south and the fast release of pheromones, only one opening is set on the top layer of the pheromone film-like carrier with holes and no slow release (see figure 2 ), used for stable and effec...

Embodiment 2

[0051] Example 2. Application of insect pheromone film carrier products in the control of different pests in the same crop

[0052] In the tobacco field, it is necessary to control Spodoptera litura, Pediatricia litura, and cutworms. In the preparation stage, the sex pheromones of Spodoptera litura, Pediatricum tabacum, and cutworms are added to three different pheromone membranes according to a certain amount. In the sub-level pheromone storage layer of the carrier; then each piece of pheromone storage layer is stacked up and down with the bottom non-slow-release layer, the second slow-release film layer, and the top non-slow-release layer with holes, respectively. It is heat-sealed into three parts along the periphery; then the three parts are spliced ​​together by certain means, and one insect pheromone film-like carrier product can be used to target the three pests of Spodoptera litura, tobacco budworm and small cutworm. Film-like carrier products (see Figure 4 ).

Embodiment 3

[0053] Example 3. Application of Insect Pheromone Film Carrier Products in Different Application Scenarios

[0054] Insect pheromone products are used for pest control in the park, but it will inevitably create a bad impression on tourists. It is expected that the products can have different colors and shapes. In order to meet the needs of park users, insect pheromone film carrier is specially selected as the carrier of the product. In the preparation process, you can choose a colored non-sustained-release layer material or paste a colored pattern on the non-sustained-release layer material. In order to make the shape beautiful, only the area where the pheromone storage layer is placed in the middle of the pheromone film carrier is fixed into a core by heat sealing area, other areas can be made into circles, triangles, flowers, etc. in order to ensure a beautiful appearance but without adding pheromones after heat sealing (see Figure 5 ).

Abstract

The invention discloses preparation and application methods of a pheromone film-like carrier. The film-like carrier consists of a bottom non-sustained-release layer, a secondary pheromone storage layer, a secondary sustained-release film layer and a top non-sustained-release layer with holes, and the layers can be heat-sealed into a whole body which is compact in periphery and hollow in interior and can adsorb pheromone; the bottom non-sustained-release layer and the top non-sustained-release layer are made of PET/EAA, PET/PE, aluminum foil or the like, the storage layer is made of a plastic film, filter paper, a fiber sheet, a sponge sheet and the like, and the sustained-release film layer is made of PE, PVC, PP or the like. The non-sustained-release layers limit release of the pheromone;the secondary storage layer adsorbs the pheromone; the secondary sustained-release film layer releases the pheromone; pheromone release holes are formed in the non-sustained-release layers, and movable non-sustained-release shielding sheets are preferably arranged on the holes; and the film-like carrier is adjustable in size and shape and can be spliced. The pheromone film-like carrier is used for insect pheromone isotropic and repellent products and directly arranged in the natural environment; and the pheromone film-like carrier is used for insect pheromone attraction products and needs tobe matched with a matched trap for application.

Description

technical field [0001] The invention relates to the application field of chemical ecology pheromones, in particular to a preparation and application method of a pheromone film carrier. Background technique [0002] Pheromone is a general term for trace chemical information substances that play a role in chemical communication between organisms. The chemical information communication for insects is insect pheromone, which mainly transmits various trace chemical information substances such as aggregation, foraging, mating, and warning to insects. Among them, sex pheromones are released by females to attract males to come to mate. trace chemical information substances. In addition, among plants, between plants and animals, and between different animals, there is also information communication composed of trace chemical information substances. [0003] For a period of time, my country has mainly relied on chemical pesticides in the control of agricultural and forestry pests. T...
