Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a packaging box for releasing flower velvet parasite eggs. Background Technology

[0002] The flower-tailed parasitic beetle primarily targets borer pests in forestry and fruit trees, showing significant control effects, particularly against longhorn beetles such as the pine sawyer beetle, the spotted longhorn beetle, the mulberry longhorn beetle, the white-striped longhorn beetle, and the poplar longhorn beetle. Traditional chemical control methods often lead to increased pesticide resistance in pests and environmental pollution. The flower-tailed parasitic beetle, however, achieves ecological balance through "using insects to control insects," resulting in no pollution or residue, aligning with the direction of green forestry development. Its highly efficient parasitic ability and environmentally friendly characteristics have made it a core species for the biological control of borer pests in forestry. However, it also has its shortcomings. For example: 1. Poor environmental adaptability of egg cards: When traditional egg cards are directly exposed in the forest, they are easily washed away by rain and exposed to the sun, which leads to egg inactivation. For example, unprotected egg cards may cause the hatching rate to drop by more than 30% on rainy days. Existing egg cards lack biomimetic structural design and cannot simulate the microenvironment of bark cracks, resulting in a high risk of predation by natural enemies. 2. Functional defects of the release device: Some devices have unreasonable vent design or insufficient sealing, which can lead to damage to the egg card during transportation; there is a lack of convenient suspension or fixing structure, which requires additional tools such as staples, increasing the complexity of operation; To address the aforementioned issues, we have innovated the design based on the existing packaging box structure for releasing the flower velvet parasite egg card. Utility Model Content

[0003] The purpose of this invention is to provide a packaging box for releasing the egg card of the flower velvet parasite, so as to solve the problems mentioned in the background art of poor environmental adaptability of the egg card and functional defects of the release device.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a packaging box for releasing the egg card of the flower velvet parasite, comprising a box body, an outer layer, an inner layer, a coating, a flow channel, a first pre-perforation, and a connecting plate. The outer layer is fixedly connected to the inner side of the box body, and the inner layer is bonded to the inner side of the outer layer. The coating is bonded to the inner side of the inner layer. The flow channel is fixedly connected to the bottom of the box body, and the first pre-perforation is provided on the inner side of the box body. The connecting plate is fixedly connected to the top of the box body, and the second pre-perforation is provided on the inner side of the connecting plate. A biodegradable cotton rope passes through the inner side of the second pre-perforation and the first pre-perforation, and both ends of the biodegradable cotton rope are connected to an external suspension rod. A biomimetic texture is fixedly connected to the outer side of the box body.

[0005] Preferably, the outer layer is made of hydrophobic PLA.

[0006] Preferably, the inner layer is made of breathable pulp.

[0007] Preferably, the material used for the coating is chitosan-based water-sensitive.

[0008] Preferably, the guide channel is viewed as an inverted "V" shaped structure.

[0009] Preferably, the depth of the biomimetic texture is between 0.3 and 0.5 mm.

[0010] Compared with the prior art, the beneficial effect of this utility model is that the packaging box for the release flower velvet parasite egg card is provided with: 1. Biomimetic microenvironment design: Biomimetic texture, the surface of the egg card simulates the texture of tree bark, reducing the detection rate of natural enemies (such as ants) by 40%, while increasing the stability of egg attachment; 2. Dynamic protection structure: Double-layer biodegradable membrane, with an outer layer of hydrophobic PLA and an inner layer of breathable pulp, combined with a bottom V-shaped flow channel to ensure an egg survival rate of ≥95% during heavy rain (compared to only 65% ​​for traditional egg cards); 3. Integrated suspension structure: pre-perforated + biodegradable cotton rope design, reducing user fixation time to 10 seconds / lock, and improving wind resistance to level 7; 4. Humidity-responsive protective layer: The inner layer is coated with a chitosan-based water-sensitive coating, which automatically shrinks to form vents when the air humidity is >80%, preventing mold growth inside the egg card; 5. Fully biodegradable design: The box (PLA + pulp) completely degrades in the natural environment in 6 months, leaving no microplastic residue. Compared with traditional plastic packaging, the fully biodegradable solution reduces carbon emissions by 82% (life cycle analysis data). Through material innovation, structural optimization, and improvements in ecological adaptability, significant advantages have been achieved in terms of breeding efficiency, release effect, production application, and environmental compliance.
