Experimental hanging cage disease control spraying hanging cage net

The hanging cage used in the spraying experiment of the CDC is a core experimental instrument dedicated to the efficacy determination of the spray space of sanitary insecticide sprays. It is often used in conjunction with the hanging cage method to evaluate the insecticidal effect. Its product design, parameters, etc. are all in line with the needs of the field experiment of disease control. The following is a detailed introduction:

1. core purpose

   It is mainly used to place mosquitoes, flies and other test insects. After the completion of space spray, through observing the test insects in the cage, accurately evaluate the on-site insecticidal effect of the spray agent. It is a key instrument for testing the spraying effect of mosquito control agent in the prevention and control of dengue fever and other insect borne infectious diseases. In some scenes, it can also be adapted to the effect evaluation of new spraying methods such as unmanned aerial vehicle spray, and it can also be set to control the hanging cage to exclude irrelevant factors such as environment from interfering with the experimental results.

2. Key specification parameters

   According to GB/T 27781 series standards, the mainstream standard model is cylindrical mesh cage, with a length of 250mm and a diameter of 100mm; some experimental scenarios will also use custom specifications, such as the model with a diameter of 150mm and a height of 250mm used in the UAV spray experiment. The material is mostly nylon sand mesh or copper mesh, with mesh sizes commonly ranging from 1.2mm × 1.2mm to 1.6mm × 1.6mm. This ensures that insecticide mist particles can enter the cage smoothly and come into contact with the test insects, while also preventing them from escaping. A 15mm diameter insect hole will be opened in the center of one end of the cage for easy placement and removal of test insects. Some customized models will also optimize the opening design to improve operational convenience.

3. Core Features

• Highly practical: The net body is transparent, which can ensure that the agents in the spray uniformly act on the test insects in the cage, ensure the authenticity of the experimental data, and the material is stable, which will not react with common sanitary pesticides, so as to avoid affecting the efficacy determination.

• Portable and easy to operateThe overall weight is light and can be easily hung on a fixed pole, suitable for standard hanging height requirements of 1-1.5m above the ground; The structure is simple, easy to clean and disinfect before and after the experiment, reusable, and reduces experimental costs.

• wide adaptabilityThe specifications can be fine tuned according to the type of insect being tested. In addition to conventional mosquitoes and flies, the size can also be adjusted to meet the experimental needs of some small vector organisms. It is compatible with most outdoor and semi outdoor spraying experimental scenarios of the disease control center.

4. Requirements for using matching equipment

   In use, 30 mosquitoes or flies are usually placed in each hanging cage, and they need to be hung on the fixed rod perpendicular to the spray route. Usually, points are set at 10m, 30m and 50m away from the spray route. The experimental environment should meet the conditions that the temperature is not lower than 23 ℃, the wind speed is 0.8-4m/s and there is no rainfall. After spray, the test insects should be transferred and fed according to the specified time. Finally, the efficacy evaluation should be completed through the mortality index.
