Now schistosomiasis is a relatively common and relatively prevalent disease. After scientific knowledge, it is known that the blood-sucking susceptibility zone has a long line of 1,449Km, which poses a serious threat to our humans and animals. We need to find out the distribution of cercaria in susceptible water bodies as soon as possible. Adopting targeted measures to eliminate cockroaches is of paramount importance.
The nylon mesh bag is the best choice for this experiment. The nylon mesh bag is safe and non-toxic and will not affect the experimental results.
In the waters of the blood-sucking susceptible area, we used the nylon net bag fishing method and the C-6 film stick method to detect the 
schistosomiasis cercariae in the water body and made a comparative observation. The nylon net bag fishing method is in the water area to be tested. After each water surface is harvested 13 times (0.1 m2) in sequence, the numbered, folded nylon mesh bag is immersed in a test tube containing 5% formaldehyde solution, brought back to the room with 800-1000 ml of clean water to rinse the mesh bag, and the liquid is passed through the filter plate.

The above is the introduction of a nylon mesh bag for scientific experiments. The choice of nylon mesh bags requires regular production. Otherwise it is very easy to use when it is used. Whether it is industrial or agricultural use.
