Description

Technical Field

[0001] This invention belongs to the field of mosquito breeding, specifically relating to a mosquito breeding device and breeding method. Background Technology

[0002] Currently, many universities and pest control companies in the industry have established their own mosquito breeding laboratories. Their main purpose is to conduct scientific research, develop insecticides, and master new methods of mosquito control. Laboratory mosquito breeding plays a crucial role in providing research subjects for scientific research. It allows for the study of which drugs mosquitoes have developed resistance to, the monitoring of the entire product development process, and provides a basis for the future development of new insecticides. Simultaneously, it studies mosquito biodiversity and habits, providing technical support for mosquito species identification and control measures. Furthermore, it establishes mosquito laboratory domestication methods, breeding, and conservation, providing mosquito and technical support for research on drug resistance mechanisms, basic drug research, indoor efficacy evaluation, and outdoor efficacy evaluation.

[0003] The mosquito life cycle generally consists of four stages: egg, larva, pupa, and adult. Eggs, larvae, and pupae all require water, while adult mosquitoes must remain in the water. Current laboratory mosquito rearing typically involves raising larvae in a basin, transferring them to clean beakers after pupation, and then transferring the beakers containing the pupae to clean mosquito cages for incubation. After the female mosquitoes have fed, they are placed in beakers containing water to lay their eggs. This entire process requires separate rearing containers, which is not only time-consuming and labor-intensive, but also inefficient. Furthermore, it's crucial to prevent pupae from hatching and flying away if they cannot be transferred in time. Additionally, mosquito cages are generally made of fabric sleeves, which are difficult to clean and prone to mold, resulting in low cage reusability and high rearing costs.

[0004] Therefore, a new technology is needed to solve the problems of low efficiency and high cost in existing mosquito breeding techniques. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a mosquito breeding device and method, which have the advantages of high efficiency and low cost in mosquito breeding.

[0006] The present invention adopts the following technical solution:

[0007] A mosquito breeding device includes a cover, a partition, and a box. The top of the box has an opening. The cover is installed at the opening and is detachably fixed to the box. The cover is used to open or cover the opening at the top of the box. The cover has a window, and a baffle is installed at the window. The baffle is used to open or close the window. A lighting element is installed inside the cover.

[0008] The partition is installed inside the box and located below the cover. A first feeding chamber is formed between the partition and the bottom of the box, and a second feeding chamber is formed between the partition and the cover. When the side of the partition abuts against the inner wall of the box, the first feeding chamber and the second feeding chamber are separated. When the projected area of ​​the partition in the vertical direction inside the box decreases, the first feeding chamber and the second feeding chamber are connected.

[0009] The side of the box is provided with a first water inlet, a second water inlet and a first water outlet that are connected to the first breeding chamber. The first water inlet is located above the first water outlet. Isolation nets are installed at the first water outlet, the first water inlet and the second water inlet to block larvae from passing through. A filter device is provided at the second water inlet.

[0010] As a further improvement to the technical solution of the present invention, the top of the cover is provided with a mounting hole, which is used to install lighting components or to communicate with an air supply device.

[0011] As a further improvement to the technical solution of the present invention, a through groove is horizontally opened on the side of the box, the through groove allows the partition to pass through, the thickness of the partition matches the height of the through groove, and a handle is provided on the partition, the handle protruding from the through groove and located outside the box;

[0012] When the partition moves horizontally relative to the through channel within the through channel, the first feeding chamber and the second feeding chamber are connected or separated.

[0013] As a further improvement to the technical solution of the present invention, a plurality of protrusions are provided on the inner wall of the box at intervals, and each of the protrusions is located on the same horizontal plane, and the bottom of the partition plate abuts against the upper surface of each of the protrusions.

[0014] As a further improvement to the technical solution of the present invention, the dimensions of the inner wall of the box gradually decrease from top to bottom.

[0015] As a further improvement to the technical solution of the present invention, the partition includes a plate body and a limiting part that are fixedly connected to each other. When the side of the plate body away from the limiting part abuts against the inner wall of the box, the first feeding chamber and the second feeding chamber are separated. The limiting part is embedded in the through groove and fills the through groove.

[0016] The handle is installed on the side of the limiting portion away from the plate body;

[0017] The thickness of the plate and the limiting part in the vertical direction are matched with the height of the through groove in the vertical direction, and the plate is provided with an upward-opening groove.

[0018] As a further improvement to the technical solution of the present invention, a second water outlet is provided at the bottom of the box, and a sealing plate is installed at the second water outlet. The sealing plate is used to open or close the second water outlet.

[0019] As a further improvement to the technical solution of the present invention, the box body includes a side plate and a bottom plate. The side plate is cylindrical, the through groove is located on the side plate, and the horizontal cross-section of the side plate is circular and the size gradually decreases from top to bottom.

[0020] The bottom plate is annular, and the central hole of the bottom plate forms the second water outlet. The bottom plate and the sealing plate together close the bottom opening of the side plate. The cover is installed on the upper end of the side plate and is used to open or cover the top opening of the side plate.

[0021] The limiting part is arc-shaped.

[0022] As a further improvement to the technical solution of the present invention, the cover is in the shape of an inverted bowl, and the maximum size of the bottom of the cover is smaller than the size of the top opening of the side plate but larger than the size of the plate body.

[0023] A mosquito breeding method, using the mosquito breeding device described above, includes the following steps:

[0024] S1. Close the first and second water outlets, open the second water inlet and the filter device, and inject water into the tank through the second water inlet to the appropriate water level;

[0025] S2. Install the lighting fixture at the mounting hole on the top of the cover, open the top lighting fixture inside the cover, and set the lighting duration to D:L = 12h:12h, that is, the lighting duration for the entire growth and development stage of mosquitoes is: 12 hours of light time and 12 hours of darkness time per day.

[0026] S3. Place the newly hatched mosquito larvae into the first rearing chamber, open the window and feed them yeast powder in small amounts and frequently. After the mosquito larvae reach the second instar, feed them yeast powder + pig liver powder to increase their nutrition.

[0027] When the mosquitoes are in the larval stage, the partition is always open, and the first rearing chamber is connected to the second rearing chamber, so that the mosquito larvae can receive the illumination from the lighting device.

[0028] Change the water every two days. When changing the water, open the first outlet and the first inlet at the same time, and make the water flow from the first outlet the same as the water flow from the first inlet. When the water is no longer cloudy, close the first inlet and the first outlet at the same time.

[0029] S4. Reduce the amount of feed given to mosquitoes during their pupal stage.

[0030] S5. After the mosquitoes have emerged, add 5% glucose solution to the sponge and place the sponge on the partition. Move the partition in the trough until it partially covers the top of the first feeding chamber. Change the glucose solution every two days.

[0031] S6. After all the mosquitoes have emerged as adults, inject tap water filtered by the filtration device into the first rearing chamber through the second water inlet until the water level reaches the partition. After all the adult mosquitoes in the first rearing chamber have flown into the second rearing chamber, move the partition until it is in contact with the inner wall of the chamber, completely separating the first and second rearing chambers.

[0032] The mice were shaved and secured with mousetrap, and placed on a partition. Mice that could be fed to mosquitoes were placed in the partition after 5:00 PM on the same day, and the mice were removed at 9:00 AM the following day.

[0033] S7. Observe the blood-sucking behavior of adult mosquitoes. After the adult mosquitoes have digested the blood they have sucked for 24-48 hours, observe that the adult mosquitoes' abdomens have turned white. Place a beaker filled with dechlorinated water on a partition for the adult mosquitoes to lay eggs. After the adult mosquitoes lay eggs in the beaker, transfer the beaker to a constant temperature incubator.

[0034] S8. After the mosquitoes complete a growth cycle of larva-pupa-adult-egg-laying in the box, the remaining adult mosquitoes are killed by physical methods.

[0035] S9. Drain all excess water from the tank, remove the lighting unit from the top of the cover, thoroughly clean the tank with detergent and rinse with clean water.

[0036] S10. Connect the mounting holes on the cover to the air supply device to dry the feeding device, and then spray 75% alcohol to thoroughly disinfect the entire feeding device to prevent the growth of bacteria.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] The design of the first inlet and the first outlet facilitates water exchange and drainage when the water becomes turbid during the rearing process, making operation convenient and improving the efficiency of the rearing work. The partition separates or connects the upper and lower parts of the inner cavity formed by the connection between the box and the cover. The lower part of the partition inside the box is the first rearing chamber for raising mosquito larvae, and the upper part of the partition inside the box is the second rearing chamber. After the mosquitoes emerge, the partition can be pulled open to connect the first and second rearing chambers. Food can be placed on the partition to feed adult mosquitoes, and the partition is detachable. The mosquito rearing device of this solution has a simple structure and can be used for the rearing and breeding of mosquitoes throughout their entire life cycle, with low manufacturing and rearing costs.

[0039] The cover has a window, which facilitates the feeding and mosquito capture. A baffle is installed at the window to open or close it. The cover is equipped with lighting to ensure the light required for mosquito growth, and the switching of the lighting in each mosquito breeding device does not interfere with each other.

[0040] A filter device is installed at the second water inlet. The second water inlet can be directly connected to tap water. The filter device can filter the tap water into pure water and then deliver it into the box for the breeding of mosquito larvae. There is no need to let the tap water sit overnight before use, which improves the efficiency of the breeding work. Attached Figure Description

[0057] The following will provide a clear and complete description of the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The same reference numerals used throughout the accompanying drawings indicate the same or similar parts.

[0058] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. Furthermore, the descriptions of "up," "down," "left," and "right" used in this invention are only relative to the relative positional relationships of the various components of the invention in the accompanying drawings.

[0059] Reference Figures 1 to 8 A mosquito breeding device includes a cover 1, a partition 24, and a box 2. The box 2 has an opening at the top. The cover 1 is installed at the opening and detachably fixed to the box 2. The cover 1 is used to open or close the opening at the top of the box 2. The cover 1 has a window 11, which facilitates the feeding of food and the capture of mosquitoes. A baffle 12 is installed at the window 11, which is used to open or close the window 11. A lighting element is installed inside the cover 1 to ensure the light required for mosquito growth. Multiple devices can be set up to breed multiple groups of mosquitoes according to experimental needs, and the switching of the lighting elements in each mosquito breeding device does not interfere with each other. The lighting element is preferably an LED light.

[0060] The partition 24 is installed inside the box 2 and located below the cover 1. A first rearing chamber 25 is formed between the partition 24 and the bottom of the box 2 for feeding mosquito larvae, and a second rearing chamber is formed between the partition 24 and the cover 1 for feeding adult mosquitoes. The portion of the box 2 below the partition 24 is preferably made of waterproof materials such as tempered glass or stainless steel. When the side of the partition 24 abuts against the inner wall of the box 2, the first rearing chamber 25 is separated from the second rearing chamber. When the projected area of ​​the partition 24 in the vertical direction within the box 2 decreases, the first rearing chamber 25 becomes connected to the second rearing chamber. The spacing between the inner walls of the box 2 located at both ends of the channel 214 is adapted to the diameter of the plate 241. The partition 24 can be pulled out to half of the plate 241, blocking the channel 214 and disconnecting the channel 214 from the interior of the box 2, thus preventing mosquitoes from escaping from the channel 214. At this time, the partition 24 covers half of the top of the first rearing chamber 25. The first rearing chamber 25 is an aquatic rearing chamber used for raising mosquito larvae, and the second rearing chamber is an adult mosquito rearing chamber used for raising adult mosquitoes.

[0061] The side of the enclosure 2 is provided with a first water inlet 212, a second water inlet, and a first water outlet 213, which are connected to the first rearing chamber 25. The first water inlet 212 is located above the first water outlet 213. Isolation nets are installed at the first water outlet 213, the first water inlet 212, and the second water inlet to prevent larvae from passing through. A water inlet pipe 5 is installed on the outside of the enclosure 2 at the first water inlet 212, and a water outlet pipe 6 is installed on the outside of the enclosure 2 at the first water outlet 213. A filter device 4 is installed at the second water inlet, which can be directly connected to tap water. The filter device 4 can filter the tap water into purified water before it is introduced into the enclosure 2 for the rearing of mosquito larvae, eliminating the need to let the tap water sit overnight, thus improving the efficiency of the rearing process.

[0062] When water needs to be changed during the rearing process, the first inlet 212 and the first outlet 213 are opened simultaneously. Once the water is no longer turbid, both inlet 212 and outlet 213 are closed. This facilitates timely water changes and drainage when the water becomes turbid, and the operation is convenient, improving rearing efficiency. The partition 24 separates or connects the upper and lower parts of the inner cavity formed by the connection between the box body 2 and the cover 1. The lower part of the partition 24 inside the box body 2 is the first rearing chamber 25, used for raising mosquito larvae. The upper part of the partition 24 inside the box body 2 is the second rearing chamber. After the mosquitoes emerge as adults, the partition 24 can be pulled open to connect the first and second rearing chambers. Food can be placed on the partition 24 to feed adult mosquitoes, and the partition 24 is detachable. This mosquito rearing device has a simple structure and can be used for the rearing and breeding of mosquitoes throughout their entire life cycle, with low manufacturing and rearing costs.

[0063] Specifically, the partition 24 is provided with an upward-facing groove 2411. The groove 2411 can be used to place food, which is beneficial for feeding adult mosquitoes. The specific position of the groove 2411 on the partition 24 can be set according to the actual situation.

[0064] Specifically, the top of the cover 1 is provided with a mounting hole 13, which is used to install a lighting component or to connect with a ventilation device. During the breeding process, a lighting component can be installed at the mounting hole 13, while the mounting hole 13 is in a blocked state, preventing adult mosquitoes from escaping through the mounting hole. When the breeding process is over and the mosquito breeding device needs to be cleaned, the lighting component can be removed. After cleaning, the ventilation pipe 3 is installed at the mounting hole 13, which can be connected to the ventilation device. The ventilation device supplies air into the mosquito breeding device of this solution, which can be used for drying after cleaning, ensuring a dry breeding environment and preventing the growth of microorganisms that could affect the breeding quality. The ventilation device is preferably a blower.

[0065] Specifically, the mosquito breeding device of this solution also includes a mounting plate for fixing the lighting component. The mounting plate is installed at the mounting hole 13 and seals the mounting hole 13. The lighting component is installed on the side of the mounting plate facing the inside of the cover 1. The cover 1 has a mounting seat 14 protruding upward at the mounting hole 13 on its top. The mounting seat 14 is hollow and can be an integral structure with the cover. In this case, the central hole of the mounting seat 14 forms the mounting hole 13. The mounting seat 14 is used to fix the ventilation pipe 3 and the mounting plate, which can facilitate the fixed connection between the cover 1 and the mounting plate or the ventilation pipe 3. During the breeding process, the mounting plate 14 can be fixed to the mounting seat 14 using a common detachable fixing connection method. After the breeding process is completed, the mounting plate can be removed before cleaning. After cleaning, the ventilation pipe 3 can be connected to the mounting seat 14, and air supply devices such as blowers can supply air into the device through the ventilation pipe 3 to dry the device.

[0066] Specifically, a first annular plate 31 protrudes from one end of the ventilation duct 3. The first annular plate is tightly connected to the ventilation duct, and there is no air leakage at the connection point between the first annular plate and the ventilation duct. The mounting base 14 includes a T-shaped cylindrical body 141 and a second annular plate 142 that are tightly connected. The inner diameter of the body 141 is adapted to the inner diameter of the second annular plate 142. Both ends of the body 141 are tightly connected to the cover 1 and the second annular plate 142, respectively. The outer diameter of the first annular plate 31 is not less than the inner diameter of the second annular plate 142. When the ventilation duct 3 needs to be installed, the first annular plate 31 and the second annular plate 142 can be fixedly connected. The size of the mounting plate is not less than the inner diameter of the second annular plate 142. When lighting components are needed, the mounting plate can be fixedly connected to the second annular plate 142.

[0067] Specifically, the cover 1 can be perforated, with several through holes 15 on it. A mesh is installed on the inner or outer side of the cover 1 to prevent mosquitoes from passing through. The mesh openings are smaller than the size of the mosquitoes. During the breeding process, when a dark environment is needed, a light-blocking cloth can be placed over the mosquito breeding device or the outside of the cover 1.

[0068] Specifically, a horizontal through-slot 214 is provided on the side of the box 2, through which the partition 24 can pass. The thickness of the partition 24 matches the height of the through-slot 214. A handle 242 is provided on the partition 24, which protrudes from the through-slot 214 and is located outside the box 2. When the partition 24 moves horizontally relative to the through-slot 214 within the box 2, the first feeding chamber 25 is connected to or separated from the second feeding chamber. The volume or cross-sectional size of the partition 24 within the box 2 can be changed by moving the partition 24.

[0069] Specifically, the inner wall of the box 2 is provided with a plurality of protrusions at intervals, all of which are located on the same horizontal plane, and the bottom of the partition 24 abuts against the upper surface of each of the protrusions. When the cross-sectional size of the box 2 is the same from top to bottom, such as a hollow cylindrical shape or a barrel shape with a quadrilateral or other polygonal cross-section, the partition 24 can be prevented from falling to the bottom of the box 2 by providing protrusions on the inner wall of the box 2 to support it.

[0070] Specifically, the dimensions of the inner wall of the box 2 gradually decrease from top to bottom. The cross-sectional dimension of the inner wall of the box 2 located below the through groove 214 is smaller than the dimension of the partition 24. In this case, there is no need to set a protrusion, so that the partition 24 embedded in the through groove 214 can maintain a relatively stable horizontal state.

[0071] Specifically, refer to Figure 7 and 8 The handle 242 is plate-shaped or ring-shaped. The partition 24 includes a plate body 241 and a limiting part 243 fixedly connected to each other. When the side of the plate body 241 away from the limiting part 243 abuts against the inner wall of the box 2, the first feeding chamber 25 is separated from the second feeding chamber. At the same time, the limiting part 243 is embedded in the through groove 214 and fills the through groove 214. The handle 242 is fixed to the side of the limiting part 243 away from the plate body 241, as shown in the figure. Figure 7The handle 242 can be located at one end of the limiting part. When it is necessary to separate the first feeding chamber 25 from the second feeding chamber, the partition 24 is inserted into the through groove 214. The handle 242 can be located at one end of the through groove 214, so that the partition 24 can be inserted into the through groove 214 and filled according to the position of the handle 242. When it is necessary to pull out part of the structure of the plate 241 on the partition 24 from the first feeding chamber 25, during the process of moving the plate 241 out, part of the handle 242 can be moved into the through groove 214. The plate 241, the limiting part 243, and the handle 242 together fill the through groove 214 so that the through groove 214 is always in a blocked state. The length of the handle 242 can be selected according to the actual situation. When it is necessary to pull out a portion of the structure of the plate 241 on the partition 24 from the first feeding chamber 25, the plate 241 can also be pulled out partially. In this case, a filling block made of materials such as sponge is used to fill the unfilled space in the through groove 214 to completely seal the through groove 214. The plate 241 and the limiting part 243 have the same thickness in the vertical direction and match the height of the through groove 214 in the vertical direction. The thickness of the partition 24 is equal to or slightly less than the height of the through groove 214.

[0072] Specifically, the bottom of the housing 2 is provided with a second water outlet 221, and a sealing plate 23 or a sealing end cap is detachably installed at the second water outlet 221. The sealing plate 23 is used to open or close the second water outlet 221.

[0073] Specifically, the housing 2 includes a side plate 21 and a bottom plate 22. The side plate 21 is cylindrical, and the housing 2 has a bowl-shaped structure. The through groove 214 is located on the side plate 21. The horizontal cross-section of the side plate 21 is circular, and its size gradually decreases from top to bottom. The bottom plate 22 is annular, and the central hole of the bottom plate 22 forms the second water outlet 221. The bottom plate 22 and the sealing plate 23 together close the bottom opening of the side plate 21. The cover 1 is installed on the upper end of the side plate 21. The cover 1 is used to open or cover the top opening 211 of the side plate 21. The through groove 214 is semi-circular, and the plate 241 is an inverted frustum shape. The horizontal cross-section of the plate 241 is circular. The limiting part 243 is semi-circular, partially covering the side of the plate 241 and tightly connected to the plate 241. The handle 242, the limiting part 243, and the plate 241 can be integrally formed.

[0074] Specifically, the cover 1 is shaped like an inverted bowl. The maximum size of the bottom of the cover 1 is smaller than the size of the top opening 211 of the side plate 21 but larger than the size of the plate body 241. The upper opening of the side plate 21 is larger than the bottom size of the cover 1, which can prevent accidental contact with the bottom of the cover 1 and thus avoid displacement of the cover 1, thereby preventing gaps from forming between the cover 1 and the side plate 21 that would allow mosquitoes to escape.

[0075] A mosquito breeding method, using the mosquito breeding device described above, includes the following steps:

[0076] S1. Close the switch valves set at the first water outlet, the second water outlet, and the first water inlet. Open the switch valve at the second water inlet and the filter device 4 and connect it to the tap water. Filter the tap water through the filter device and inject it into the tank 2 through the second water inlet to the appropriate water level.

[0077] S2. Install the lighting fixture at the mounting hole on the top of the cover and seal the mounting hole to prevent adult mosquitoes from escaping through the gap in the mounting hole. Open the top lighting fixture inside the cover 1. The lighting fixture is an LED light. The lighting duration is set to D:L = 12h:12h, that is, maintain 12 hours of light and 12 hours of darkness per day. The lighting duration for the entire growth and development stage of mosquitoes is set to maintain 12 hours of light and 12 hours of darkness per day.

[0078] S3. Place the newly hatched mosquito larvae into the first rearing chamber 25. When feeding is needed during the rearing process, open window 11 to feed small amounts of yeast powder frequently. After the mosquito larvae reach the second instar, feed them yeast powder + pig liver powder to increase their nutrition. When the mosquitoes are in the larval stage, pull open partition 24 to connect the aquatic rearing chamber and the adult rearing chamber. During this period, partition 24 remains open, ensuring that the first rearing chamber 25 and the second rearing chamber are always connected, allowing the mosquito larvae to receive LED light illumination. During the larval stage, partition 24 can be completely pulled out of the channel 214, or a large portion of partition 24 can be pulled out of the channel 214. When partition 24 is completely pulled out of the channel, a semi-circular filler block can be placed inside the channel 214 to completely fill it. The filler block has a protrusion; when the filler block completely fills the channel 214, the protrusion is located on the outside of the channel 214 and the chamber 2. The first rearing chamber 25 is the aquatic rearing chamber, and the second rearing chamber is the adult rearing chamber.

[0079] During this period, the water is changed every two days. When changing the water, the first outlet 213 and the first inlet 212 are opened at the same time, and the water flow rate of the first outlet 213 is kept consistent with the water flow rate of the first inlet 212. When the water is no longer turbid, the first inlet 212 and the first outlet 213 are closed at the same time.

[0080] S4. During the pupal stage of mosquitoes, reduce the amount of feed appropriately, while keeping other conditions consistent with the previous feeding process.

[0081] S5. After the mosquitoes have emerged, add 5% glucose solution to the sponge and place the sponge in the groove 2411 on the partition 24. Move the partition 24 in the channel 214 to partially cover the top of the aquatic breeding tank or cover about half of the top area of ​​the aquatic breeding tank. Change the glucose solution every two days. The partition 24 has a groove 2411 with the opening facing upward.

[0082] S6. After all the mosquitoes have emerged as adults, inject filtered tap water into the first rearing chamber through the second water inlet until the water level reaches the partition. Once all the adult mosquitoes in the first rearing chamber have flown into the second rearing chamber, move the partition 24 until it is in contact with the inner wall of the chamber 2, completely separating the first and second rearing chambers.
