Description

Technical Field

[0001] The utility model relates to the technical field of blood-sucking mosquito prevention and control, in particular to a feeding device for breeding mosquitoes. Background Art

[0002] Blood-sucking mosquitoes are vectors of many infectious diseases, among which Anopheles, Aedes, and Culex are the most important vectors and are important factors in infectious diseases such as dengue fever, malaria, yellow fever, filariasis, and Japanese encephalitis. With the passage of time and the large-scale use of insecticides, mosquitoes have gradually become more resistant to conventional pesticides, which has brought great difficulties to the prevention and control of mosquito-borne diseases. Therefore, a comprehensive mosquito control strategy should be adopted in the process of mosquito control to reduce excessive reliance on chemical pesticides.

[0003] The Sterile Insect Technique (SIT) uses radiation to treat target insects, causing chromosomal abnormalities in their sperm cells, resulting in infertility. The target insects are then continuously released in large quantities into the area where the target insects occur. The infertile male insects mate with wild male insects to produce infertile offspring, thereby causing the extinction of local populations. This insect control method can effectively block the reproduction of blood-sucking insects and is an effective strategy for preventing mosquito-borne diseases.

[0004] Large-scale release of sterile blood-sucking mosquitoes can be used to prevent blood-sucking mosquitoes from spreading pathogens through vector insects. Solving the problem of indoor large-scale breeding of blood-sucking mosquitoes is the core of the sterile insect release method, and how to efficiently feed blood-sucking mosquitoes has become a key link in SIT technology.

[0005] At present, laboratory breeding generally uses live animals for female mosquitoes to suck blood. The specific operation method is: fix the laboratory-raised mice with their abdomens facing upwards, cut off the abdominal hair, and put them in a special mosquito cage for female mosquitoes to suck their blood. After the female mosquitoes finish feeding, take out the mice and feed them glucose to supplement their nutrition.

[0006] The main drawbacks of the above method are that feeding mosquitoes to mice for a long time causes great damage to the mice. If the operation is not careful, it is very easy to cause ischemia and death of the mice. In addition, the use of live animals for feeding is unethical and moral standards, and unnecessary harm to experimental animals should be avoided as much as possible. Summary of the invention
