Description

Technical Field

[0001] The present invention relates to the technical field of biological breeding equipment, and specifically refers to a mosquito breeding ecological breeding system. Background Art

[0002] Mosquitoes belong to the phylum Arthropoda, class Insecta, order Diptera, and family Culicidae, and are the most important medical insects. They are the vectors of various infectious diseases such as malaria, Japanese encephalitis, filariasis, dengue fever, chikungunya, etc. Currently, up to 265 viruses have been isolated from mosquitoes, accounting for 50% of the total number of registered arboviruses. Research on mosquitoes involves disciplines such as entomology, parasitology, epidemiology, and health and epidemic prevention. Therefore, it is one of the most widely and deeply studied insect groups in the class Insecta. The research on mosquitoes requires extensive field investigations and laboratory breeding. Complete and diverse mosquito specimens are the basis for carrying out research on their biology, ecology, morphological taxonomy, molecular biology, and drug resistance. Especially in biological research and inspection and quarantine work, it is often necessary to breed and observe mosquitoes to obtain experimental data for mosquito drug efficacy testing, species identification, specimen production, etc.

[0003] The existing mosquito breeding ecological breeding system with the publication number CN114586746B is disclosed. It connects an adult mosquito box and a larva box through a hollow channel, uses a mosquito attracting lamp to control the movement of adult mosquitoes between the adult mosquito box and the larva box, configures a feeding box in the adult mosquito box, sets a water tank in the larva box, and sets an automatic feeding component for feeding the larvae in the water tank. It is expected to achieve the characteristics of no manual intervention, safe protection of the entire growth stage of mosquitoes, and reduction of mosquito damage and escape. However, in actual use, this mosquito breeding ecological breeding system requires manual observation of the hatching situation of adult mosquitoes, and then controls the mosquito attracting lamp to guide the movement of adult mosquitoes. It is necessary to control both the feeding and egg laying of adult mosquitoes, and the adult mosquitoes need to move back and forth between the adult mosquito box and the larva box, which is a huge workload for the observers. In addition, in the actual operation process, even with the guidance of the mosquito attracting lamp, due to the reflection of the water surface, the guiding effect on adult mosquitoes is not good. Moreover, due to the setting of multiple corrugated structures, such as the corrugated telescopic part at the water tank and the corrugated joints in the central control channel, water vapor is easily collected at the corrugated folds, and adult mosquitoes are more likely to stay at the folds, which is instead not conducive to the observation and cultivation of mosquitoes.

[0004] All of the above make the practicality of this mosquito breeding ecological breeding system not good. It can neither reduce the workload of the observers nor provide a suitable environment for the growth and reproduction of mosquitoes. In order to ensure the smooth progress of the entire growth stage of mosquitoes and facilitate the observers to observe, there is an urgent need to provide a new mosquito breeding ecological breeding system. Summary of the Invention

[0005] The object of the present invention is to provide a mosquito breeding ecological feeding system that minimizes manual intervention, reduces the workload of observers, meets the needs of observation experiments, and provides a suitable growth and reproduction environment for all growth stages of mosquitoes.

[0006] The present invention is achieved through the following technical solutions: a mosquito breeding ecological feeding system, including a box body with an open upper part, the lower part of the box body is the larva area, the upper part of the box body is the adult mosquito area, a coarse pore grille is arranged between the larva area and the adult mosquito area for separation, a nutrient solution for larva breeding is contained in the larva area, a screen for closing the top of the adult mosquito area is hooped on the top of the box body, an opening extending upward is arranged in the middle of the screen, and the opening in the screen is sealed and tied; a feeding trough is arranged on the upper inner side of the adult mosquito area, and a nutrient solution for adult mosquitoes to suck is contained in the feeding trough; a water inlet pipe is arranged on one side of the larva area, and a water outlet pipe is arranged on the other side of the larva area.

[0007] According to the living habits of mosquitoes, adult mosquitoes lay eggs on the water surface. The hatched larvae, called wigglers, live and move in the water. After molting four times, the larvae turn into pupae and finally hatch into adult mosquitoes. For mosquitoes, as long as there is sufficient food, suitable temperature, humidity, and corresponding living and breeding environment, they can reproduce and survive in large numbers. Based on this, this technical solution directly provides a living environment that meets the entire growth stage of mosquitoes. The lower larval area is used for mosquitoes to lay eggs, and the nutrient solution in the larval area provides nutrition and environment for the growth of larvae. After hatching, the mosquitoes can fly and leave the water surface to survive in the upper adult mosquito area. The feeding trough in the adult mosquito area provides a feeding trough for adult mosquitoes, and the nutrient solution in the feeding trough provides nutrition for the growth and reproduction of adult mosquitoes. The upper part of the box is open, mainly to provide sufficient oxygen for the box environment, so that mosquitoes do not grow and reproduce in a completely enclosed environment. The screen set on the top of the box prevents adult mosquitoes from flying out and escaping. The opening in the middle of the screen, on the one hand, can directly put various nutrients into the box through the opening, including the nutrient solution in the feeding trough and the nutrient solution in the larval area; on the other hand, the development of the ovaries of female mosquitoes must suck blood. Therefore, small animals such as mice can be put into the box through the opening to provide a blood source for female mosquitoes. After sucking, the small animals that have been sucked of blood are taken out through this opening and waited to be sucked again. This opening is also the main opening for taking out adult mosquitoes. Adult mosquitoes can be taken out through the opening for relevant experiments. The thick-hole grille that divides the box into a larval area and an adult mosquito area serves as a bearing place for small animals, preventing small animals from contacting the nutrient solution in the lower larval area. This thick-hole grille does not block the adult mosquitoes hatched from the pupae from entering the adult mosquito area and can effectively separate the adult mosquito area from the larval area, facilitating the observation of mosquitoes. An inlet pipe and an outlet pipe are set in the larval area to regularly replace the nutrient solution in the larval area, so that there are always nutrient components in the larval area for the growth of larvae. The inlet pipe and the outlet pipe can also form a slow-circulating liquid system to keep the nutrient solution in the larval area in a state of slow flowing live water, so that there is sufficient oxygen in the nutrient solution in the larval area.

[0008] To better implement the present invention, further, a water-absorbing cotton wadding is laid in the feeding trough, one end of the water-absorbing cotton wadding is laid in the feeding trough, and the other end extends out of the feeding trough and hangs downwards.

[0009] To better implement the present invention, further, the nutrient solution for larvae to reproduce contained in the larval area is clear water added with at least one of liver powder, steamed bun powder, and yeast powder.

[0010] To better implement the present invention, further, a filter screen is also set at the inlet of the outlet pipe.

[0011] To better implement the present invention, further, a feeder is also set on the inlet pipe.

[0012] To better implement the present invention, further, the nutrient solution for adult mosquitoes to suck in the feeding trough is glucose water.

[0013] To better implement the present invention, further, a constant temperature heater is also provided at the bottom of the box body.

[0014] To better implement the present invention, further, the material of the box body is transparent glass.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] (1) The present invention simplifies the structure of the mosquito breeding ecological feeding system. Without any guidance to mosquitoes, it separates adult mosquitoes from larvae according to the habits of mosquitoes and does not affect the egg-laying process of adult mosquitoes. The box body of the whole system is neither completely cut off from the outside, nor can it avoid mosquito damage and escape. Moreover, through the liquid circulation in the lower larval area, the metabolic products of mosquitoes can be discharged, providing a more favorable environment for the breeding and growth of mosquitoes.

[0017] (2) The mosquito breeding ecological feeding system provided by the present invention can minimize the process of manual intervention. The addition of the nutrient solution is basically carried out once a month, and the liquid circulation period in the lower larval area is also once a month. This can greatly reduce the workload of the observation and experiment personnel in raising mosquitoes. Moreover, due to the adoption of a unified box body structure, the distribution of mosquitoes is more concentrated and obvious, facilitating the observation of the observation and experiment personnel.

[0018] (3) The mosquito breeding ecological feeding system provided by the present invention has a relatively simple structure, reasonable structural settings, can ensure the smooth progress of all growth stages of mosquitoes, is convenient for observers to observe, has a low manufacturing cost, good practicability, and is suitable for wide promotion and application.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can also be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Embodiment 1:

[0026] The main structure of this embodiment, as Figure 1 shown, includes a box body 1 with an open upper part. The lower part of the box body 1 is a larva area 2, and the upper part of the box body 1 is an adult mosquito area 3. A coarse hole grille 4 is provided between the larva area 2 and the adult mosquito area 3 for separation. The larva area 2 is filled with a nutrient solution for larva reproduction. A screen 5 that closes the top of the adult mosquito area 3 is hoop-mounted on the top of the box body 1. An opening extending upward is provided in the middle of the screen 5, and the opening in the screen 5 is sealed and tied. An upper inner side of the adult mosquito area 3 is provided with a feeding trough 6, and the feeding trough 6 is filled with a nutrient solution for adult mosquitoes to suck. A water inlet pipe 7 is provided on one side of the larva area 2, and a water outlet pipe 8 is provided on the other side of the larva area 2.

[0027] During the breeding process of mosquitoes, first remove the upper screen 5, close the water inlet pipe 7 and the water outlet pipe 8, inject clean water into the larval area 2 at the lower part of the box body 1 through the opening at the upper part of the box body 1, and add nutrients so that the larval area 2 is filled with nutrient solution for larval reproduction. The nutrient solution in the larval area 2 is not higher than the position where the coarse-hole grid 4 is located. Then add larvae. Then inject nutrient solution for adult mosquitoes to suck in the feeding trough 6. Finally, hoop the screen 5 on the top of the box body, and seal and tie the opening in the middle of the screen 5. In this way, the construction of the entire mosquito breeding ecological breeding system is completed. The aperture of the screen 5 is not less than 120 mesh, which can effectively prevent mosquitoes from escaping and flying out.

[0028] After 3 to 7 days, adult mosquitoes begin to hatch in the larval area 2. The adult mosquitoes can pass through the coarse-hole grid 4 and enter the adult mosquito area 3. After all the larvae are completely hatched into adult mosquitoes, open the water inlet pipe 7 and the water outlet pipe 8, and replace the nutrient solution in the larval area 2. At this time, the adult mosquitoes are distributed in the adult mosquito area 3 at the upper part of the box body 1. Carefully open the opening in the screen 5, place a small animal with its hair removed and its limbs tied on the coarse-hole grid 4 for the female mosquitoes among the adult mosquitoes to suck blood, ensuring the development of their fertilized eggs and ovaries so that they can lay eggs. Then still take out the small animal after blood-sucking through the opening. Since the upper part of the screen is connected to the external environment, the adult mosquitoes will not gather at the opening of the screen 5. During the process of adding or taking out the small animal, the mosquitoes will not gather in large numbers. Especially the female mosquitoes after sucking enough blood will not gather around the small animal anymore. The female mosquitoes will fly to the water surface of the larval area 2 to lay eggs after fertilization. In this way, the entire mosquito breeding ecological breeding system is formed by repeating the process.

[0029] Since female mosquitoes only suck blood during the breeding process, the cycle of adding small animals can be controlled, and thus the entire mosquito breeding ecological breeding system can be controlled.

[0030] Embodiment 2:

[0031] On the basis of the above embodiment, in this embodiment, a water-absorbing cotton wadding 9 is further arranged in the feeding trough 6. As Figure 1 shown, the water-absorbing cotton wadding 9 is laid in the feeding trough 6. One end of the water-absorbing cotton wadding 9 is laid in the feeding trough 6, and the other end extends out of the feeding trough 6 and hangs downwards. In order to facilitate the mosquitoes to suck the nutrient solution in the feeding trough 6, the water-absorbing cotton wadding 9 is specially arranged. One end of the water-absorbing cotton wadding 9 is in the feeding trough 6 and immersed in the nutrient solution, and the other end extends out of the feeding trough 6 and hangs down. The bottommost part of the hanging end of the water-absorbing cotton wadding 9 does not contact the coarse-hole grid 4. The water-absorbing cotton wadding 9 uses the siphon effect to suck the entire nutrient solution for the mosquitoes to suck. Since the nutrient solution in the feeding trough 6 is not suitable for the growth of larvae, the adult mosquitoes will not lay eggs in the water-absorbing cotton wadding 9 and the nutrient solution in the feeding trough. Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0032] Embodiment 3:

[0033] On the basis of the above embodiments, this embodiment further defines the composition of the nutrient solution in the larval area 2. The nutrient solution for larval reproduction contained in the larval area 2 is clear water added with at least one of liver powder, steamed bun powder, and yeast powder. In order to fully utilize the habits of mosquito larvae and adults, the nutrient solutions for feeding larvae and adult mosquitoes are specifically set to be different, so that adults and larvae can be further separated. The larvae of mosquitoes - wigglers generate water currents through the bristles in their mouths to bring plankton and organic debris in the water into their mouths. Therefore, it is preferably to add at least one of liver powder, steamed bun powder, and yeast powder to the clear water as the nutrient component for the larvae to eat. Other parts of this embodiment are the same as those of the above embodiments and will not be elaborated.

[0034] Example 4:

[0035] On the basis of the above embodiments, this embodiment further adds a filter screen 10. As Figure 1 shown, a filter screen 10 is also provided at the inlet of the water outlet pipe 8. The filter screen 10 at the water outlet pipe 8 can block mosquito larvae and prevent the larvae of mosquitoes from flowing out. Other parts of this embodiment are the same as those of the above embodiments and will not be elaborated.

[0036] Example 5:

[0037] On the basis of the above embodiments, this embodiment further adds a feeder 11. As Figure 1 shown, a feeder 11 is also provided on the water inlet pipe 7. Although nutrients can be directly added to the lower larval area 2 through the opening of the upper screen 5, in order to reduce the chance of mosquito escape, a feeder 11 is added on the water inlet pipe 7 to directly add the nutrient components of the larval area to the larval area 2 through the water inlet pipe 7. Other parts of this embodiment are the same as those of the above embodiments and will not be elaborated.

[0038] Example 6:

[0039] On the basis of the above embodiments, this embodiment further defines the composition of the nutrient solution in the feeding trough 6. The nutrient solution for adult mosquitoes to suck in the feeding trough 6 is glucose water. Using glucose water as the nutrient for adult mosquitoes can prevent adult mosquitoes from laying eggs in the feeding trough 6, and glucose water cannot be used as the liquid environment for breeding mosquito larvae. Other parts of this embodiment are the same as those of the above embodiments and will not be elaborated.

[0040] Example 7:

[0041] On the basis of the above embodiment, a constant-temperature heater 12 is further provided in this embodiment, and the constant-temperature heater 12 is also provided at the bottom of the box body 1. The optimal growth and reproduction temperature of mosquitoes is 27 °C, and water has a large specific heat capacity. Therefore, as long as the temperature of the water body in the larva area 2 is ensured to be 27 °C, the temperature environment and humidity environment in the adult area 3 can be ensured, providing an optimal living and breeding environment for mosquitoes. Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0042] Embodiment 8:

[0043] On the basis of the above embodiment, the material of the box body 1 is further defined in this embodiment, and the material of the box body 1 is transparent glass. Here, it is preferably that the material of the box body 1 is transparent glass, which can facilitate the experimenter to directly observe the body habits and living conditions of mosquitoes outside the box body 1.

[0044] It can be understood that for the structure of the mosquito breeding ecological feeding system according to an embodiment of the present invention, the working principles and processes of components such as the water inlet pipe 8 and the constant-temperature heater 12 are all prior art and well-known to those skilled in the art, and will not be described in detail here. Other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
