A ladybug oviposition paper

Abstract

This utility model discloses a ladybug oviposition paper, comprising a surface layer, a middle layer, a bottom layer, and a textured layer. The bottom of the surface layer is bonded to the middle layer, and the bottom of the middle layer is bonded to the bottom of the bottom layer. The textured layer is fixedly connected to the top of the surface layer. This ladybug oviposition paper adopts a three-layer composite structure: surface layer: light yellow biodegradable plant fiber membrane; middle layer: breathable and waterproof nanofiber layer; bottom layer: environmentally friendly pressure-sensitive adhesive. The overall structure is simplified, employing a modular unit design: cut into 6cm×6cm squares with perforated edges, allowing for quick assembly into a large oviposition area without manual folding or fixing accessories; it is simply tear-and-stick. The color is light yellow, the texture is a laser-engraved grid pattern on the back of leaves, and the scent inducer is impregnated with trace amounts of aphid pheromones. In use, multiple sheets of oviposition paper are spliced ​​together in the field to form an "oviposition belt," which is then hung on the back of crop stems or leaves to attract ladybugs to lay eggs and establish natural enemy insects.

Description

Technical Field

[0001] This utility model relates to the field of oviposition paper technology, specifically a ladybug oviposition paper. Background Technology

[0002] Ladybugs are a widely distributed group of Coleoptera insects, attracting much attention due to their vibrant colors and significant ecological value. They are "natural guardians" of ecological balance, but their protection and utilization require scientific management to avoid the risk of biological invasion. As a biological control tool, ladybug oviposition paper technology currently suffers from the following disadvantages in its application:

[0003] 1. High complexity of operation and high dependence on manual labor: In the existing technology, the production of oviposition paper requires multiple manual operations, such as folding paper, cutting double-sided tape, fixing plugs, etc., which increases the production cost and time. Such a design is inefficient when applied on a large scale, and manual operation is prone to errors (such as glue position deviation), which affects the attachment stability of ladybug eggs.

[0004] 2. Insufficient environmental adaptability: Existing oviposition paper has poor environmental tolerance.

[0005] (1) Sensitive to humidity and light: Avoid direct sunlight and rain, otherwise the glue may fail or the paper may deform;

[0006] (2) Lack of weather-resistant materials: Ordinary paper is prone to mold in humid environments and may degrade with long-term outdoor use, reducing the survival rate of eggs;

[0007] 3. Fixing method and usage scenario limitations

[0008] (1) Unstable fixation: It relies on staples or plugs for fixation and is easily detached by wind or animals;

[0009] (2) Limited application scenarios: It is mainly used for hanging on tender branches and buds, and it is difficult to adapt to the needs of tall crops or complex terrain (such as orchards and forests);

[0010] 4. The egg's protective mechanism is weak.

[0011] (1) Exposure risk: The eggs are directly attached to the surface and are easily damaged by natural enemies (such as ants) or pesticides;

[0012] (2) Lack of incubation environment control: The temperature and humidity regulation function is not integrated, and the hatching rate is significantly affected by fluctuations in the external environment.

[0013] 5. Inadequate adaptation to egg-laying behavior

[0014] (1) Lack of optimization in color and texture design: Existing technologies mostly use conventional colors (such as white or green) and do not specifically simulate the yellow or leaf back texture preferred by ladybugs, resulting in insufficient attractiveness;

[0015] (2) Limited material selection: Ladybugs' oviposition preferences for different materials (such as biodegradable fibers and breathable materials) were not considered;

[0016] 6. Issues related to large-scale production and costs

[0017] (1) High production costs: The manual production process is difficult to automate, and the cost of mass production is high;

[0018] (2) Low reuse rate: Most of them are single-use designs, without considering cleanable or reusable solutions, which increases the long-term cost of use.

[0019] To address the aforementioned issues, we have developed an innovative design based on the existing ladybug egg-laying paper structure. Utility Model Content

[0020] The purpose of this invention is to provide a ladybug oviposition paper to solve the problems mentioned in the background art, such as high operational complexity and reliance on manual labor, insufficient environmental adaptability, limitations in fixing methods and usage scenarios, weak egg protection mechanisms, insufficient adaptability to oviposition behavior, and issues related to large-scale production and cost.

[0021] To achieve the above objectives, this utility model provides the following technical solution: a ladybug egg-laying paper, comprising a surface layer, a middle layer, a bottom layer, and a texture; the bottom of the surface layer is bonded to the middle layer, and the bottom of the middle layer is bonded to the bottom of the bottom layer; the top of the surface layer is fixedly connected to the texture.

[0022] Preferably, the material used for the surface layer is a light yellow biodegradable plant fiber membrane.

[0023] Preferably, the intermediate layer is made of breathable and waterproof nanofiber.

[0024] Preferably, the material used for the bottom layer is environmentally friendly pressure-sensitive adhesive, and release paper is bonded to the bottom of the bottom layer.

[0025] Preferably, the texture is a laser-micro-engraved mesh pattern on the back of the blade, with a depth of 0.1 mm and a spacing of 0.5 mm between adjacent textures.

[0026] Compared with the prior art, the beneficial effect of this utility model is that the ladybug egg-laying paper:

[0027] It adopts a three-layer composite structure: the top layer is a light yellow biodegradable plant fiber film (containing a chlorophyll biomimetic coating to simulate leaf luster), the middle layer is a breathable and waterproof nanofiber layer (moisture-proof and mildew-proof), and the bottom layer is an environmentally friendly pressure-sensitive adhesive (removable and residue-free). The overall structure is simplified and adopts a modular unit design: cut into 6cm×6cm squares with perforated edges, it can be quickly spliced ​​into a large oviposition area without manual folding or fixing accessories; it can be torn and pasted immediately. The color is light yellow (wavelength 550-580nm, matching the visual sensitivity area of ​​ladybugs), the texture is a laser-micro-engraved grid pattern on the back of leaves (depth 0.1mm, spacing 0.5mm), and the odor inducement is a trace amount of aphid pheromone (concentration 1ppm, attracting ladybugs to gather). When in use, multiple oviposition papers are spliced ​​together in the field to form an "oviposition belt," which is then hung on the back of crop stems or leaves to attract ladybugs to lay eggs and establish natural enemy insects.

[0038] I. Working principle of egg-laying paper

[0039] 1. Color and spectral sensitivity

[0040] Ladybugs are sensitive to the yellow and green spectrum, which is close to the wavelength of light reflected from plant leaves (550-580nm). Using light yellow or leaf-colored oviposition paper can effectively attract ladybugs to lay eggs.

[0041] 2. Texture 4

[0042] Bionic Texture 4: Surface 1 uses laser micro-engraving or embossing technology to form micro-convex and concave textures similar to the back of a leaf (such as grid or honeycomb), which enhances the ladybug's tactile perception and simulates the natural egg-laying environment;

[0043] 3. Material Selection

[0044] Breathability and water absorption: The surface layer 1 is made of plant fiber paper or biodegradable material to maintain appropriate humidity and prevent eggs from becoming inactive due to dryness;

[0045] Environmental friendliness: Non-toxic materials ensure that it is harmless to ladybugs and the environment;

[0046] II. Experimental Verification Data

[0047] 1. Ladybug oviposition preference test:

[0048] Leaf Shadow-I type vs. ordinary yellow paper → egg production increased by 42% (p<0.01);

[0049] 2. Humidity tolerance test:

[0050] At 85% humidity, Leaf Shadow-I type paper showed no mold growth for 7 days, while traditional paper developed fungal spots after 3 days.

[0051] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
