Swallow, the larva of mosquito, is the intermediate stage of mosquito growth from egg to pupa, and it is a mosquito-eating fish. Because it has a certain effect on killing the larvae of Anopheles mosquitoes and other mosquitoes, it is pollution-resistant, adaptable and highly reproductive, and has been introduced to all parts of the world for mosquito control purposes.
Mosquito-eating fish has strong adaptability, which can not only live in rivers, ponds, swamps, paddy fields and other water bodies, but also be kept in small water bodies such as small pools, mosquito-eating fish rockery pools, family lotus pots and vases. It can live in the water temperature of 5 ~ 40℃, and usually likes to swim in the water in groups. The surface of mosquito-eating fish is agile.
Mosquitoes generally feed on small invertebrates. Because it has no stomach and a short digestive tract, it can be described as voracious when it preys on mosquito larvae. When the water temperature is suitable, each fish can swallow 40 ~100 mosquito larvae one day and night, and at most can swallow more than 200 mosquitoes.
Using mosquito-eating fish to kill mosquitoes can not only pollute the environment, but also eliminate mosquito larvae in water, which can effectively control the breeding of mosquitoes. If mosquito-eating fish are widely cultivated everywhere, it will be of great benefit to eliminate mosquitoes and effectively control and prevent infectious diseases spread by mosquitoes.
