Description

[Technical Field]

[0001] This utility model relates to the monitoring of disease vector density, and more particularly to a mosquito trapping and monitoring device. [Background Technology]

[0002] Dengue fever is one of the most prevalent vector-borne viral diseases in humans today, and the primary vector for the dengue virus is the Aedes mosquito (tiger mosquito). Globally, approximately 50 to 100 million dengue fever cases occur annually, of which 500,000 progress to more severe dengue hemorrhagic fever and dengue shock syndrome. In recent years, the number of dengue fever cases in my country has been on the rise. The most effective emergency control measure after a dengue outbreak is the rapid eradication of the vector—the Aedes mosquito—to cut off the source of transmission and control the spread of the outbreak. Monitoring and assessing the density of the Aedes mosquito, the dengue vector, is a crucial means of epidemic prevention and control.

[0003] The following content is disclosed in section 2.10.2 of the national standard GB / T 23797-2020 "Methods for Monitoring Vector Density - Mosquitoes":

[0004] 2.10.2.3 Operating Procedures

[0005] Mosquito nets should be placed in sheltered, shady locations. Monitoring should be conducted during peak activity periods of adult mosquitoes in the local area. During monitoring, the person attracting the mosquitoes sits inside the enclosed inner mosquito net, exposing their lower legs. They manually raise the outer net until its bottom is 250mm-300mm off the ground, attracting mosquitoes for 30 minutes, or a timer set according to the monitoring objectives. Then, the person attracting the mosquitoes lowers the outer net from inside the inner net, completely enclosing the attracted mosquitoes. After taking personal protective measures inside the inner net, they exit and collect the mosquitoes that have landed on it using an electric mosquito suction device or a handheld mosquito sampler within the space between the two layers of netting. The mosquitoes are then collected, classified, and counted.

[0006] The national standard GB / T 23797-2020 "Methods for Monitoring the Density of Vector-borne Organisms - Mosquitoes" requires staff to sit in a closed mosquito net for a long time as the attractant, which consumes a lot of staff time and is not conducive to the effective implementation of mosquito density monitoring and assessment.

[0030] The structure and principle of the mosquito trapping and monitoring device in this embodiment of the utility model are as follows: Figures 1 to 12As shown, it includes a closed enclosure 100, an enclosure support 10, an electric mosquito suction device 20, a wire mesh cage 30 for holding and attracting animals, a mosquito trap 50, and a wire mesh cage support 40.

[0031] The wire mesh cage 30 has an entrance / exit 31 on its side for attracting animals, and a cage door 32 is installed on the entrance / exit 31. The bottom of the wire mesh cage 30 has a tray 33 to improve the comfort of the animals and facilitate the fixing of the cage support 40. The bottom of the wire mesh cage 30 is fixed to the top of the cage support 40, which consists of three upright support legs 41.

[0032] The enclosure support 10 includes four legs 11 arranged circumferentially along the wire mesh cage 30, a cross support 12, and an annular support plate 13. The ends of the four struts of the cross support 12 are respectively connected to the inner circumference of the annular support plate 13. The lower ends of the legs 11 are connected to the upper part of the outer side of the wire mesh cage 30. The upper ends of the four legs 11 are respectively connected to the bottom surfaces of the four struts of the cross support 12. The mosquito trap 50 sits on the top surface of the wire mesh cage 30, located between the four legs 11. A certain amount of water can be placed in the mosquito trap 50 to attract mosquitoes to lay eggs.

[0033] The enclosure 100 includes an enclosure body 60 and a mosquito trap 22 for an electric mosquito aspirator 20. The enclosure body 60 and the mosquito trap 22 for the electric mosquito aspirator 20 are made of breathable mosquito net fabric.

[0034] The top of the cover body 60 includes an inwardly tapering annular shoulder 61. The cover body 60 fits over the cover support 10 and the wire mesh cage 30. The annular shoulder 61 of the cover body 60 is supported by the top surface of the annular support plate 13 of the cover support 10. The top surface of the support plate 13 is shaped like the side of a first frustum, which is smaller at the top and larger at the bottom. The shape of the shoulder 61 of the cover body 60 matches the shape of the top of the support plate 13.

[0035] Supported by the top surface of the annular support plate 13, the cover body 60 covers the outside of the wire mesh cage 30, and the dynamic mosquito suction device 20 is also fixed above the wire mesh cage 30 by the cover bracket 10. A gap is left between the outer perimeter of the wire mesh cage 30 and the inner side of the cover body 60, and the lower end of the cover body 60 is approximately level with the bottom of the wire mesh cage 30. Because the wire mesh cage 30 is fixed to the cage bracket 40, the lower end of the cover body 60 is suspended in the air.

[0036] An electric mosquito trap 20 is positioned on top of the enclosure 100. The electric mosquito trap 20 includes a base plate 21, a mosquito trapping bag 22, a fan 23, a battery (not shown in the figure), and a conical frame 24. The base plate 21 has a mosquito suction port in the middle, and the fan 23 is installed at the mosquito suction port of the base plate 21. The inner periphery of the lower part of the mosquito trapping bag 22 is connected to the outer periphery of the base plate 21.

[0037] The mosquito trap 22 is cone-shaped, wider at the bottom than the top. The annular opening at the bottom of the mosquito trap 22 is connected to the shoulder 61 of the cover 60 via a first zipper 25. The bottom plate 21 of the mosquito suction device is shaped like the side of a second truncated cone, wider at the bottom than the top. The suction port is located on the upper bottom surface of the second truncated cone, directly above the wire mesh cage 30.

[0038] The mosquito trap 22 is supported by a conical frame 24, the lower end of which is supported by an annular support plate of the cover bracket. The fan 23 is battery powered. The mosquito trap 22 includes a mosquito collection opening, which is equipped with a second zipper 26 for opening and closing.

[0039] The working process of the mosquito trapping and monitoring device according to this embodiment is as follows: The device is set up at the monitoring point. An appropriate amount of water is placed in the mosquito trap box 50, and sentinel animals are kept in the wire mesh cage 30. The fan of the electric mosquito suction device 20 is turned on. When the device is working, it uses the scent of the sentinel animals to attract mosquitoes. Mosquitoes enter the enclosure 60 from below. Mosquitoes entering the enclosure 60, and those entering and exiting the wire mesh cage 30, are drawn upwards by the suction force of the electric mosquito suction device 20 and the mosquitoes' attraction to water, and are finally sucked into the mosquito trapping bag 22 of the electric mosquito suction device 20.

[0040] This invention's mosquito trapping and monitoring device can serve as an important means of monitoring the spread of vector-borne viruses. Caged sentinel animals are typically selected that are highly sensitive to specific viruses, such as rabbits, mice, and chickens, which reflect the activity of viruses within the ecosystem. This invention's mosquito trapping and monitoring device, through the integrated application of sentinel animal monitoring, mosquito population monitoring, laboratory testing and data analysis, environmental factor monitoring, and a real-time monitoring and early warning system, can comprehensively and promptly monitor the spread of vector-borne viruses, providing a scientific basis for the formulation of prevention and control measures.

[0041] This utility model embodiment of the mosquito trapping and monitoring device uses caged sentinel animals as mosquito attractants, eliminating the need for staff on duty, saving manpower, and reducing the risk of staff infection with viruses.
