Problems solved by technology

The common physical method is electric mosquito lamp. This method will produce the smell of burning insects while killing mosquitoes, and it is easy to cause electric shock hazard.
Moreover, existing mosquito control methods are all aimed at adult mosquitoes, but there is almost no method for controlling mosquitoes for mosquito larvae (hereinafter referred to as "larvae")

Embodiment 1

[0061] A water body mosquito control device and mosquito control method based on multi-stage mosquito trapping and hydrological mosquito killing, mainly composed of a suspension carrier, a first-stage mosquito trap system, a second-stage mosquito trap system, a mosquito extermination system, a power supply system, and a central control system, etc. It consists of six parts.

[0062] Select an inland river in a city in East China to carry out an in-situ mosquito control project. The channel is located in the urban area, with a length of 600m and a width of 30m. The water quality is poor, and all water quality indicators are surface water inferior to Class V water (GB3838-2002), the fluidity of the water body is poor, and the positive rate of mosquito larvae is 70%.

[0063] In this embodiment, the mosquito control devices are installed along the length of the river with a distance of 100 m, and a total of 5 sets of mosquito control devices are installed.

[0064] In this embo...

Embodiment 2

[0072] A water body mosquito control device and mosquito control method based on multi-stage mosquito trapping and hydrological mosquito killing, mainly composed of a suspension carrier, a first-stage mosquito trap system, a second-stage mosquito trap system, a mosquito extermination system, a power supply system, and a central control system, etc. It consists of six parts.

[0073] Select an inland river in a city in East China to carry out an in-situ mosquito control project. The river is located in the urban area, with a length of 300m and a width of 20m, which has a landscape effect, and the positive rate of mosquito larvae is 60%.

[0074] In this embodiment, the mosquito control devices are installed along the length of the river with a distance of 80m, and a total of 3 sets of mosquito control devices are installed.

[0075] In this embodiment, the suspension carrier 1 is composed of a floating body 10 and a metal bracket 11. The size of the suspension carrier is 4.2×2...

Embodiment 3

[0083] A circular landscape pool in a residential area was selected to implement the project. The diameter of the pool is 10m, and the water depth of the pool is 1m. The water quality meets the Class V standard of the surface water environmental quality standard (GB3838-2002), and the positive rate of mosquito larvae is 50%.

[0084] In this embodiment, the mosquito control device is installed at the center of the pool, and a total of 1 set of water body mosquito control devices is provided.

[0085] All the other are with embodiment 1.

[0086] The in-situ mosquito control project was completed and operated for 2 months, and the monitoring results showed that some water quality indicators of the water body could reach Class III surface water quality (GB3838-2002), and the positive rate of mosquito larvae was 15%.

Abstract

The invention provides a water body mosquito control device and method based on multi-stage mosquito trapping and hydrologic mosquito killing. The device mainly comprises six portions including a suspension carrier, a primary mosquito trapping system, a secondary mosquito trapping system, a mosquito killing system, a power supply system and a central control system. The device is suitable for controlling mosquitoes of a medium and small sized surface water body which is not thorough in pollutant intercepting, is seriously polluted and breeds mosquitoes easily. The suspension carrier floats onthe water surface and supports the other systems; the primary mosquito trapping system is used for trapping mosquitoes which are away from the device to the position nearby the device; the secondary mosquito trapping system is used for further trapping the mosquitoes nearby the device to the mosquito killing system; and the mosquito killing system provides a dry and wet alternant hydrologic environment by draft change caused by buoyancy change so as to achieve a purpose of efficiently controlling the mosquitoes. Meanwhile, up-down floating of the system in the invention has an oxygenation function on the water body, the self-cleaning ability of the water body can be improved, and moreover, plants can also efficiently purify water. The device has the remarkable advantages of remarkable effect, low running cost, good installation compatibility and the like.

Description

technical field [0001] The invention relates to the technical field of public health and mosquito disease prevention and control, in particular to a water body mosquito control device and a mosquito control method based on multi-stage mosquito trapping and hydrological mosquito killing. Background technique [0002] Mosquitoes, as important vector organisms, not only suck human blood, affect sleep, but also spread diseases. Mosquitoes become long-term storage hosts for pathogens after they bite humans or livestock with pathogens, and can transmit pathogens to healthy people when they bite people again. The diseases transmitted by mosquitoes mainly include Japanese encephalitis, malaria, dengue fever and dengue hemorrhagic fever, filariasis, yellow fever, etc., which seriously endanger human health. Therefore mosquito class is the important object of sanitary pest control both at home and abroad always. [0003] The growth and reproduction of mosquitoes cannot be separated ...
