Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological control technology, specifically to a terrestrial and aquatic Trichogramma wasp nest. Background Technology
[0002] Trichogramma wasps are oviparous parasitic wasps, natural enemies of many rice stem borer pests. Released into fields, these wasps autonomously search for rice stem borer egg masses and lay their eggs inside. Once the wasp eggs develop into larvae, they feed on the rice stem borer egg fluid, preventing hatching and thus achieving pest control. Currently, Trichogramma wasp nests used in conjunction with drones have the following drawbacks: the biological containers are easily opened; during egg release in paddy fields, water often flows into the containers; the nests may also suddenly open during descent, scattering eggs; or the nests may overturn on the ground, blocking the outlet, preventing hatched eggs from escaping and causing them to die. These issues affect the normal hatching and escape of the wasps. Therefore, this case study was developed to address these problems. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides an integrated terrestrial and aquatic Trichogramma hive, solving the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a terrestrial and aquatic Trichogramma hive, comprising a spherical cavity formed by the snapping together of an upper shell and a lower shell, wherein the side wall of the upper shell is provided with a plurality of ventilation holes arranged in a ring array, a cylindrical cavity is provided inside the lower shell, the top of the cylindrical cavity is provided with a plurality of vertical elongated notches arranged in a ring array, an insert plate is provided inside the upper shell, the insert plate is inserted into the elongated notches, the upper end face of the cylindrical cavity is in contact with the upper shell, the elongated notches and ventilation holes are arranged alternately, a counterweight is provided at the lower center of the lower shell and the total counterweight of the lower shell is greater than that of the upper shell, a circular retaining ring is provided on the lower shell, and a plurality of baffles are arranged in a ring array below the circular retaining ring.
[0005] The vent holes described above have an outer smaller opening and an inner larger opening.
[0006] The adjacent vents and the elongated notch are staggered by 30°.
[0007] A certain gap is left between the above-mentioned cylindrical cavity and the lower shell.
[0008] The upper shell has an inner groove at the lower opening, and the lower shell has an outer protruding strip at the upper opening corresponding to the inner groove. The outer protruding strip engages with the inner groove. Beneficial effects
[0009] This utility model provides an integrated amphibious Trichogramma wasp nest. It has the following advantages: The integrated amphibious Trichogramma wasp nest consists of a spherical cavity formed by the interlocking of an upper shell and a lower shell. The spherical cavity structure design facilitates the rolling of the nest within the delivery device, making it convenient for delivery via drone equipment. A cylindrical cavity is provided inside the lower shell to store Trichogramma wasp eggs or wasp cards. The elongated notch at the top of the cylindrical cavity is staggered with the ventilation holes on the upper shell, so that even if water droplets enter the ventilation holes, they will not drip directly into the cylindrical cavity, reducing the risk of the eggs being soaked in water. A counterweight is provided at the center of the lower part of the lower shell, and the lower shell... The overall weight distribution is greater than that of the upper shell, achieving a self-righting structure. This ensures that the upper shell faces upwards when the wasp is dropped from the air or landed in water or on land by a drone, facilitating the subsequent flight of the Trichogramma wasps and increasing the survival rate of adult Trichogramma wasps. The lower shell is equipped with a circular baffle and a baffle plate, allowing the wasp nest to float in the water, increasing buoyancy and floating stability, and preventing the risk of the eggs being soaked if the upper shell is turned upside down in the water. After the adults emerge, they can stay on the circular baffle for a suitable time to fly away at the optimal moment, increasing the survival rate of the adults after emergence.

[0016] 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.
[0017] Example: Refer to the appendix of the instruction manual Figure 1-5 As can be seen, this application specifically designs a terrestrial Trichogramma hive, including a spherical cavity formed by the snap-fitting of an upper shell 1 and a lower shell 2. The spherical cavity structure design facilitates the rolling of the hive in the delivery device, making it easy to deliver via drone equipment. The side wall of the upper shell 1 has several ventilation holes 3 arranged in a ring array to facilitate ventilation and allow the Trichogramma bees to fly away after hatching. The lower shell 2 has a cylindrical cavity 4 inside, which is used to store Trichogramma bee eggs or bee cards. The top of the cylindrical cavity 4 has several vertical elongated notches arranged in a ring array. 5. To facilitate the escape of bee eggs and larvae, an insert plate 6 is provided inside the upper shell 1. The insert plate 6 is inserted into the elongated notch 5. The upper end face of the cylindrical cavity 4 is attached to the upper shell 1. When the upper shell 1 and the lower shell 2 are combined, the part of the cylindrical cavity 4 that protrudes from the lower shell 2 completely overlaps with the upper shell 1. This prevents bee eggs or bee larvae from falling out of the cylindrical cavity 4, increasing the safety of the bee eggs. The elongated notch 5 and the ventilation hole 3 are arranged alternately. When the honeycomb is combined, the insert plate 6 is inserted into a set of elongated notches 5 in the cylindrical cavity 4. The ventilation hole 3 of the upper shell 1 and The other elongated notches 5 in the cylindrical cavity 4 are staggered to ensure that the vent 3 and the elongated notches 5 are not aligned vertically. This prevents water droplets from dripping directly into the cylindrical cavity 4 even if they enter the vent 3, reducing the risk of eggs being waterlogged. Furthermore, the insertion plate 6 and the elongated notches 5 interlock to further improve the connection reliability between the upper shell 1 and the lower shell 2. A counterweight is located at the center of the lower part of the lower shell 2, and the total counterweight of the lower shell 2 is greater than that of the upper shell 1, achieving a self-righting structure. This ensures that the drone... When dropping the beehive into the air or landing it in water or on land, ensure that the upper shell 1 faces upwards to facilitate the flight of the Trichogramma wasps and increase the survival rate of the adult wasps. The lower shell 2 is equipped with a circular baffle 7, and several baffles 8 are arranged in a circular array below the circular baffle 7. After the beehive is dropped into the water, it can float in the water, increasing the buoyancy and floating stability in the water, and avoiding the risk of the eggs being soaked if the upper shell is turned upside down in the water. When the adults emerge, they can stay on the circular baffle 7 for a while, so that they can fly away at the best time, increasing the survival rate of the adults after emergence.
[0018] In the specific implementation process, as a preferred setting, the openings at both ends of the above-mentioned ventilation hole 3 are of a structure with a smaller outer opening and a larger inner opening, which facilitates the larvae to crawl out and can effectively reduce the entry of water droplets into the interior.
[0019] In the specific implementation process, as a preferred setting, the adjacent vents 3 and the elongated notch 5 are staggered by 30°.
[0020] In the specific implementation process, as a preferred setting, a certain gap is left between the above-mentioned cylindrical cavity 4 and the lower shell 2. When water droplets enter the honeycomb, they will be stored in the gap to prevent the bee eggs from being soaked by water. When the honeycomb is placed in water or on land, the cavity will also play a role in heat preservation and insulation to prevent the bee eggs from being affected by excessively high or low temperatures, which could lead to the bee eggs hatching.
[0021] In the specific implementation process, as a preferred setting, the lower opening of the upper shell 1 is provided with an inner groove 9, and the upper opening of the lower shell 2 is provided with an outer protruding strip 10 corresponding to the inner groove 9. The outer protruding strip 10 is engaged with the inner groove 9. The upper shell 1 and the lower shell 2 adopt a split structure design and are connected by a snap fastener. The inner groove 9 and the outer protruding strip 10 cooperate with each other, so that the two can better interlock and prevent the upper shell 1 and the lower shell 2 from separating during loading, unloading, transportation and placement.
