Description

Technical Field

[0001] This utility model relates to the field of biological control technology for agricultural pests, and more specifically to a storage device for a packaging medium for transporting Trichogramma wasp eggs in the field. Background Technology

[0002] Trichogramma wasps are parasitic natural enemies of various major lepidopteran pests, such as the Asian corn borer, rice stem borer, and sugarcane borer. Releasing artificially bred Trichogramma wasps into the field can replace some chemical pesticides, thereby controlling lepidopteran pests and avoiding ecological damage caused by over-reliance on chemical pesticides. This effectively reduces pesticide residues in the environment and agricultural products, and has significant economic, social, and ecological benefits.

[0003] Currently, the main method of field deployment of Trichogramma wasps relies on specially made bee cards, plastic bee balls, and other delivery media or devices. This method has many drawbacks:

[0004] Firstly, when releasing Trichogramma wasps in the field, a single wasp card or ball can contain hundreds to tens of thousands of parasitic eggs. Due to the limited number of wasp cards and balls released, coupled with the small size and limited dispersal ability of the wasps, the distribution of released wasps in the field is uneven, resulting in inconsistent control efficacy. For example, beyond 8 meters of the release point, the Trichogramma population decreases significantly, and the control efficacy decreases significantly with increasing distance from the release point. Within 8 meters of the release point, although a high control effect can be achieved in the short term, the excessively high density of wasps in the field intensifies intraspecific competition and increases the frequency of overparasitism, thereby reducing the colonization capacity of the offspring and the long-term control level. To achieve a more ideal control level, the spacing between release points is generally required to be controlled within 15 meters. However, increasing the number of release points and the release density will increase the number of released wasps and the cost of labor or machinery, thus increasing the overall control cost.

[0005] Secondly, current field release methods for Trichogramma wasps require the special production of bee cards or release balls, and these media are often incompatible with existing agricultural machinery or equipment. This often necessitates the creation of specialized delivery devices and additional agricultural operations. Furthermore, the release of Trichogramma wasps is frequently incompatible with sowing, weeding, fertilization, soil treatment, and other pest and disease control measures, making the release method neither simple nor convenient.

[0006] Furthermore, during the storage and transportation of Trichogramma wasp media, the wasp eggs may collide within the storage device, affecting the Trichogramma wasps.

[0007] Therefore, developing a storage device for the packaging medium of Trichogramma parasitic eggs for field delivery that is suitable for agricultural granule spreaders and easy to store is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the present invention provides a storage device for a packaging medium for the field delivery of Trichogramma parasitic eggs, which is applicable to agricultural granule spreaders and is easy to store.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A storage device for a packaging medium for parasitic Trichogramma wasp eggs used in field delivery, comprising:

[0011] The media particles, on which Trichogramma wasp eggs are attached to the surface of the media particles;

[0012] A storage cylinder, the inside of which is provided with a placement net, on which medium particles with Trichogramma wasp eggs attached are placed; a buffer layer is provided on the side wall of the storage cylinder;

[0013] A cylinder cover, which is hinged to the top of the storage cylinder and is mesh-shaped.

[0014] The beneficial effects of adopting the above technical solution are that the medium particles can be applied to spreaders, etc., making it convenient to spread the medium particles; at the same time, the buffer layer inside the storage cylinder can prevent Trichogramma wasp eggs from hitting the cylinder wall during transportation and causing damage.

[0015] Preferably, the medium particles are straw particles, and both their diameter and length are within 5 mm.

[0016] Preferably, the surface of the media particles is coated with an adhesive. The adhesive allows the bee eggs to adhere firmly to the surface of the media particles.

[0017] Preferably, a soluble syrup dilution is sprayed onto the surface of the media particles on which Trichogramma wasp eggs are attached.

[0018] Preferably, an ice pack and a moisturizing gauze are placed at the bottom of the storage cylinder, and the ice pack and the moisturizing gauze are located below the placement net.

[0019] Preferably, the buffer layer is a bubble wrap film, which adheres to the inner wall of the storage cylinder and is positioned above the placement net. The bubble wrap film elastically absorbs transport shocks, preventing media particles from colliding hard with the cylinder wall.

[0020] Preferably, a handle is provided at the top of the outer wall of the storage cylinder.

[0021] Preferably, the mesh size of the placement net is 10 mesh, and the mesh size of the cylinder cover is 5 mesh.

[0022] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a storage device for a packaging medium for parasitic Trichogramma wasp eggs used for field delivery, and its beneficial effects are as follows:

[0023] (1) The bee egg packaging medium is compatible with all conventional granule spreaders and does not require special bee release equipment;

[0024] (2) The bubble wrap has a certain elasticity to prevent collisions during the transportation of Trichogramma wasp eggs;

[0025] (3) Ice packs and moisturizing gauze can control the temperature and humidity inside the storage container for a certain period of time. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model embodiment discloses a storage device for a bee egg packaging medium used for field delivery of Trichogramma parasitic eggs, comprising:

[0037] Media particle 1, Trichogramma wasp eggs 2 are attached to the surface of media particle 1;

[0038] Storage cylinder 3, with a placement net 4 inside, on which medium particles 1 with Trichogramma wasp eggs 2 are placed; a buffer layer 31 is provided on the side wall of storage cylinder 3;

[0039] The cylinder cover 5 is hinged to the top of the storage cylinder 3 and has a mesh shape.

[0040] To further optimize the above technical solution, the medium granules 1 are straw granules with a diameter and length both within 5mm. The shape of the straw granules is not entirely regular, but the length at each angle should be within 5mm. The size limitation of the medium granules 1 makes them suitable for various handheld, backpack, and drone-mounted spreaders, fertilizer spreaders, fertilizer winnowing machines, seed spreaders, and scatterers. The straw granules with attached Trichogramma wasp eggs 2 can be spread into the field using methods such as blower-type, hydraulic, or mechanical spreading. It should be noted that if using rotary or centrifugal spreading methods, the machine speed should be carefully controlled to avoid violent collisions that could cause the parasitic eggs to be hit. Also, when using different spreading devices, the spreading nozzle should be aimed at the plant. Before use, evenly spraying 50mL of water per liter of straw granules and stirring well will help the straw granules adhere to the plant surface.

[0041] To further optimize the above technical solutions, straw pellets with attached Trichogramma wasp eggs can also be mixed with insecticide slow-release pellets, fungicide slow-release pellets, pollen and pollenin pellets, granular fertilizer, plant growth regulator slow-release pellets, pest repellent pellets, and pest mating pellets to improve the efficiency of integrated agricultural operations. However, it should be noted that some insecticide and herbicide slow-release pellets must be safe and low in toxicity to Trichogramma wasps.

[0042] To further optimize the above technical solution, an adhesive is sprayed onto the surface of the media particles 1. The adhesive can be a glue that does not affect the Trichogramma wasp eggs 2, such as gum arabic.

[0043] To further optimize the above technical solution, a soluble syrup dilution was sprayed onto the surface of the medium particles 1 with Trichogramma wasp eggs 2 attached. The soluble syrup was diluted 100 times and sprayed onto the surface of the straw particles. This increased the adhesion of the Trichogramma wasp eggs 2 to the straw particle surface and provided sugary nutrients for the Trichogramma wasps that emerge after being released into the field. By allowing the Trichogramma wasps to ingest sugars after emergence to supplement their nutrition, their lifespan was extended.

[0044] To further optimize the above technical solution, an ice pack 6 and a moisturizing gauze are placed at the bottom of the storage cylinder 3, and the ice pack 6 and the moisturizing gauze are located below the placement net 4. The ice pack 6 and the moisturizing gauze are used to control the temperature and humidity inside the storage cylinder 3 for a certain period of time.

[0045] To further optimize the above technical solution, the buffer layer 31 is a bubble wrap film, which adheres to the inner wall of the storage cylinder 3 and is located above the placement net 4. The bubble wrap film has a certain degree of elasticity to prevent collisions during the transportation of the Trichogramma wasp eggs 2.

[0046] To further optimize the above technical solution, a handle 32 is provided on the top of the outer wall of the storage cylinder 3. The handle 32 is provided to facilitate the handling of the storage cylinder 3.

[0047] To further optimize the above technical solution, the mesh size of the placement net 4 is 10 meshes, and the mesh size of the lid 5 is 5 meshes. The placement net 4 is made of nylon mesh, and the mesh design of the lid 5 ensures the breathability of the container. At the same time, the size limitation of the mesh can prevent other predatory insects and spiders from crawling into the cage to feed on the Trichogramma wasp eggs 2.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
