[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The purpose of the present invention is to provide a braconid wasp propagation device to solve the problems existing in the above-mentioned prior art, which can efficiently and conveniently complete the cleaning work on the bottom of the breeding chamber, reduce maintenance time, reduce the risk of interference, and improve the overall efficiency of experiments and breeding.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, the present embodiment provides a braconid propagation device, which is particularly used in the breeding of parasitic insects such as the Taiwan ceratogastric braconid, and includes a propagation box. The preferred propagation box has a length of 20 cm, a width of 12 cm, and a height of 13 cm. A breeding chamber 1 and a collecting chamber 2 located below the breeding chamber 1 are provided in the propagation box; a screen 4 is provided at the bottom of the breeding chamber 1, and the preferred screen 4 is a stainless steel screen 4 with a pore size of 1 to 3 mm, which has sufficient structural strength and supporting force. During the specific production, the stainless steel screen 4 with a structural size matching the bottom of the breeding chamber 1 is cut and installed on the inner side of the bottom of the breeding chamber 1. It is preferably fixed by bonding or screws to ensure durability.

[0025] Among them, the screen 4 extends in the horizontal direction, and its edges are sealed and connected to the inner wall of the breeding chamber 1. The screen 4 is paved with a stone layer for screening cocoons. The stone layer is located in the breeding chamber 1. The thickness of the preferred stone layer is 1 to 3 mm, ensuring that the stone layer is loose and breathable, so as to facilitate the cocooning of cocoons. It should be noted that the cocooning of cocoons enters the pupal stage, and the structure formed at this time is called a cocoon. The mesh structure of the screen 4 is smaller than the body structure of the cocoon and larger than the structure of a single stone. The top position of the collection chamber 2 is detachably plugged with a support plate 5, which extends into the expansion box and fits on the bottom wall of the screen 4, and the structure of the support plate 5 is not smaller than that of the screen 4. Among them, the particle size of the stone particles is 1 to 3 mm, which is adapted to the aperture of the screen 4, ensuring that after the support plate 5 is pulled out from the top of the collecting chamber 2, the stone particles can quickly pass through the screen 4 and enter the collecting chamber 2. When the cocoon wasp is the Taiwan nail-bellied cocoon wasp, the body structure of the Taiwan nail-bellied cocoon wasp is 8 to 11 mm, so that after the stone particles quickly pass through the screen 4, the cocoons of the Taiwan nail-bellied cocoon wasp can be retained on the screen 4. The device for propagating cocoons of bees disclosed in the present invention is provided with a combination of a screen 4 and a support plate 5. On the one hand, when the cocoons of bees are completed, the support plate 5 only needs to be separated from the top position of the collecting chamber 2 so that it is no longer attached to the bottom wall of the screen 4. By shaking the entire propagation box, the stones will naturally fall along the screen 4, while the cocoons will remain on the screen 4, thereby realizing the convenience of separating the cocoons from the stone layer. On the other hand, by separating the stones from the cocoons, the stones that are already covered with impurities enter the collecting chamber 2, completing the cleaning work of the bottom of the breeding chamber 1, and the screen 4 and the support plate 5 can facilitate the regular cleaning of the breeding chamber 1.

[0026] In addition, pupation paper and solid feed are also provided in the breeding chamber 1. The pupation paper is placed on the stone layer to provide support for the cocoon wasps when they are cocooning. The preferred pupation paper is made of hygroscopic cardboard, which is 18 cm long, 5 cm wide and 4 cm high. In the process of preparing the solid feed, a special feed preparation tool is used to prepare it into a feed block with a length of 12 cm, a width of 8 cm and a thickness of 1 cm, and holes are punched on its surface with a hole diameter suitable for the cocoon wasps to feed. The solid feed is placed on the stone layer and close to the pupation paper, which is convenient for the cocoon wasps to feed and convenient for observing the feeding behavior of the cocoon wasps.

[0027] In a specific embodiment, the structure of the collecting chamber 2 is large enough to collect a sufficient amount of stone particles. Each time the breeding chamber 1 is cleaned, the stone particles fall into the collecting chamber 2, and then a stone particle layer is laid on the screen 4 until the breeding is completed. The screen 4 and the support plate 5 are removed, and the stone particles collected in the collecting chamber 2 are recovered. Preferably, the collecting chamber 2 is provided with an outlet for taking out the stone particles. Then, each time the breeding chamber 1 is cleaned, the stone particles fall into the collecting chamber 2 and can be taken out through the outlet. There is no need to accumulate the stone particles in the collecting chamber 2 for a long time, and the convenience of cleaning and maintenance is greatly improved.

[0028] In a specific embodiment, the collecting chamber 2 is equipped with a collecting box 6 for entering and exiting the collecting chamber 2 from the taking-out port. The collecting box 6 is located below the supporting plate 5, and a collecting port for receiving the falling stones is provided on the top wall of the collecting box 6. By setting the collecting box 6, each time the breeding chamber 1 is cleaned, the stones fall into the collecting box 6 through the collecting port, and then the collecting box 6 is taken out from the collecting chamber 2, so that the fallen stones can be taken out from the collecting chamber 2 at one time, thereby improving the convenience of replacing the stones.

[0029] In a specific embodiment, a feeding port is provided on the side wall at the bottom of the collecting chamber 2, and two first tracks extending horizontally along the entry and exit direction of the collecting box 6 are provided on the inner side wall at the bottom of the collecting chamber 2, and the two first tracks are horizontally symmetrically distributed on both sides of the collecting box 6 along a direction perpendicular to the entry and exit direction of the collecting box 6, and respectively slide with the corresponding side edges of the collecting box 6, so as to realize setting the collecting box 6 at the feeding port by pushing and pulling the tracks, so that it is more labor-saving to take the collecting box 6 out of the collecting chamber 2, and it can ensure the smoothness when taking out the collecting box 6, and can effectively reduce the wear of the collecting box 6, and preferably a snap-fit ​​structure is provided between the collecting box 6 and the collecting chamber 2, so that after the collecting box 6 is pushed into place, the collecting box 6 is detachably connected to the collecting chamber 2 through the snap-fit ​​structure, so as to ensure that when the breeding chamber 1 is cleaned and the entire expansion box is shaken, the position of the collecting box 6 can be effectively fixed to avoid sliding, resulting in the inability of stones to fully fall into the collecting box 6.

[0030] In a specific embodiment, a mounting opening for the support plate 5 to enter and exit is opened on the top side wall of the collecting chamber 2, and the mounting opening is located below the screen 4 and close to the screen 4, so that the support plate 5 can be extended into the collecting chamber 2 or withdrawn from the collecting chamber 2 through the mounting opening. Preferably, two bosses protruding from the inner wall of the collecting chamber 2 are provided at the top position of the collecting chamber 2, and the two bosses are distributed on both sides of the support plate 5 along a direction perpendicular to the direction of entry and exit of the support plate 5, and are supported on the bottom wall of the support plate 5, so that the support plate 5 is more stable in the collecting chamber 2, thereby ensuring the supporting strength of the screen 4 and the stone particle layer.

[0031] Preferably, two second tracks are provided on the top inner wall of the collecting chamber 2, both of which extend horizontally along the entry and exit direction of the support plate 5, and the two second tracks are distributed on both sides of the support plate 5 in a direction perpendicular to the entry and exit direction of the support plate 5, and respectively slide with the corresponding two side edges of the support plate 5, so as to realize the support plate 5 being set at the installation port by pushing and pulling the tracks, so that it is more labor-saving to take the support plate 5 out of the collecting chamber 2, and preferably a snap-fit ​​structure is provided between the support plate 5 and the collecting chamber 2, so that after the support plate 5 is pushed into place, the support plate 5 is detachably connected to the collecting chamber 2 through the snap-fit ​​structure, which can ensure that the position of the support plate 5 is effectively fixed to avoid sliding, which causes stone particles to fall from the gap between the support plate 5 and the collecting chamber 2 when cleaning is not performed.

[0032] In a specific embodiment, a ventilation hole connecting the breeding chamber 1 with the external environment is opened, and the ventilation hole is located above the stone layer. By setting the ventilation hole, the outside air can flow into the breeding chamber 1 through the ventilation hole, maintain a stable oxygen level in the breeding chamber 1, and avoid air stagnation causing excessive humidity. The ventilation hole is covered with a ventilation net 3 to prevent external insects from entering the expansion box, and the mesh structure of the ventilation net 3 is smaller than the body structure of the cocoon. By setting the ventilation net 3, it is possible to prevent cocoon bees from escaping from the breeding chamber 1, and prevent external insects from entering the breeding chamber 1 and affecting the cocoon bees, and prevent dust from entering the breeding chamber 1. The preferred ventilation net 3 adopts a diamond mesh structure, which is slightly larger than the ventilation hole and has an aperture of 0.5 mm, which is convenient for material collection and arrangement. Further preferably, the top of the breeding chamber 1 is open as a whole, which is used as a ventilation hole, and it is convenient to place cocoon bees, install the screen 4 and lay the stone layer in the breeding chamber 1, and then the ventilation net 3 is arranged in a cover-like structure to seal the ventilation hole. Preferably, the ventilation net 3 is tightly combined with the top of the breeding chamber 1 by setting a slot or an interlocking method to ensure flatness and stability.

[0033] In a specific embodiment, the expansion box is equipped with a storage room for placing it, and a temperature regulator and a humidifier are provided in the storage room. First, by setting up the storage room, multiple expansion boxes can be arranged together in the storage room, and then the cultivation work of multiple expansion boxes can be carried out. Moreover, the temperature and humidity in the storage room and the cultivation chamber 1 are adjusted by the temperature regulator and the humidifier to ensure the stability of the internal environment of the cultivation chamber 1. Preferably, a temperature sensor and a humidity sensor are also provided in the storage room to feedback and adjust the temperature regulator and the humidifier, and the temperature in the storage room and the cultivation chamber 1 is controlled at 25-30°C, and the humidity is controlled at 65-75%, so as to meet the optimal growth requirements of the cocoon wasps.

[0034] In a specific embodiment, the stone particles are mineral particles with water absorption function, so as to cooperate with the temperature regulator and the humidifier to prevent the environment in the culture chamber 1 from being too dry, and preferably the mineral particles are vermiculite particles, etc. Before laying the vermiculite, clean, impurity-free vermiculite particles are selected, and vermiculite particles with a particle size of 1 to 3 mm are screened out, and then the vermiculite particles are cleaned to remove possible dust or pollutants, and dried for use.

[0035] In a specific embodiment, the outer wall of the breeding chamber 1 is a transparent structure, preferably made of transparent non-toxic plastic, so that the observer can directly see the breeding conditions inside the breeding chamber 1 through the outer wall, avoiding the observer frequently opening the cover to check the status of the cocoon wasp in the prior art, disturbing the insect development process. Furthermore, the outer wall of the collection chamber 2 and the support plate 5 are also transparent structures, so that the observer can observe the state of the stone particle layer from the bottom. The outer wall of the collection chamber 2 is preferably made of transparent non-toxic plastic, and the support plate 5 is preferably made of a glass plate with a certain support strength. Preferably, the expansion box is made of transparent non-toxic plastic as a whole. In the specific preparation process, the transparent non-toxic plastic is first processed and formed by a customized plastic molding mold using an injection molding machine to produce an expansion box that meets the size requirements.

[0036] In the experiment of propagating Taiwan's hornbill by using the hornbill propagation device disclosed in the present invention, daily observation is included, and the activity status of the hornbill needs to be checked regularly, including feeding, stinging and cocooning. During the observation, the ventilation net 3 is gently opened to avoid excessive interference with its living environment. It also includes vermiculite replacement, specifically, after each week or each experimental cycle, the collection box 6 is pulled out, the waste is screened out, and clean vermiculite is re-laid on the screen 4. It further includes feed supplementation, specifically, according to the food intake and growth cycle of the hornbill, solid feed is regularly added or replaced to ensure adequate nutrition supply.

[0037] The specific implementation cases are as follows:

[0038] Implementation case 1: 50 Formosa ceratostomidae were observed to cocoon in the propagation box. The results showed that the cocooning rate reached 86% and the cocoon integrity was good.

[0039] Implementation Case 2: Comparing the traditional closed box with the propagation box disclosed in the present invention, the cocooning rate of the former is 70%, while the cocooning rate of the latter is increased to 86%.

[0040] Implementation case three: Use vermiculite of different thicknesses (1mm, 2mm, 3mm), among which 2mm is the most suitable, providing the best drilling space.

[0041] Control experiment: The experiment was carried out at two temperatures: 20-30℃ and 30-40℃. The cocooning efficiency was higher at 20-30℃, and the cocooning rate was highest at 28℃.

[0042] In summary, the present invention greatly improves the gas exchange efficiency by opening a ventilation hole in the breeding chamber 1 and sealing the ventilation net 3 at the ventilation hole, prevents the phenomenon of humidity accumulation or excessive drying in the breeding chamber 1, maintains a suitable environmental humidity, and optimizes the ventilation conditions; a stone layer with a thickness of 1 to 3 mm is laid on the bottom of the breeding chamber 1 to facilitate the stinging and cocooning of cocoons; the setting of the screen 4 prevents the humidity at the bottom of the stone layer from being too high, further avoiding the problem of cocoon shell mildew or damage; ventilation and humidity optimization significantly improves the success rate of cocooning of cocoons by the armored cocoon, thereby achieving more efficient reproduction.

[0043] Furthermore, by setting the culture chamber 1, the collection chamber 2 and the support plate 5 to be transparent, it is convenient to directly observe the activities and growth of insects from all angles. The reasonable layout of the pupation paper makes the cocooning behavior of the cocoon wasp easier to observe. The researchers can record the cocooning process through the transparent structure, so that the behavior of the cocoon wasp can be observed in real time without opening the cover, reducing human interference, and improving the observation efficiency and the accuracy of the insect behavior data.

[0044] Furthermore, the removable support plate 5 and the detachable collection box 6 make the bottom cleaning and the stone layer replacement operations more convenient. The perforated design on the surface of the solid feed block is convenient for the cocoon wasps to feed, and the feed position is reasonably arranged, which is convenient for regular replenishment without repeatedly opening the cover. The design of the first slide rail and the second slide rail improves the stability of the operation and avoids interference with the insect environment due to improper operation. The efficient and convenient operation design reduces maintenance time, reduces the risk of interference, and improves the overall efficiency of experiments and breeding.
