Oiling of Reservoirs

Oiling of reservoirs is a method of combating mosquito larvae, based on the creation of a thin film of oil on the surface of the reservoir.

This method was used in the past to destroy the larvae of malaria mosquitoes in the USSR, USA and other countries. The essence of the method is that a very thin layer of oil is applied to the surface of the reservoir where mosquito larvae breed using special sprayers. This film prevents oxygen from reaching the surface of the water, resulting in the death of mosquito larvae.

However, over time, the use of this method was abandoned, as it leads to serious pollution of water bodies. Oil entering water damages the ecosystem, poisoning aquatic plants and animals. In addition, the oil film disrupts gas exchange between water and the atmosphere.

Currently, safer and more environmentally friendly methods are used to combat mosquitoes, such as the use of biological insecticides, treatment of reservoirs with the drug Bti (Bacillus thuringiensis israelensis), which is harmless to other organisms. Measures are also being taken to destroy breeding sites for mosquito larvae.

“Oiling of reservoirs” is a method of exterminating mosquito larvae by creating a thin layer of oil on the surface of a reservoir. This method was developed in the early 20th century and was used in various countries to control mosquitoes, which are carriers of many dangerous infectious diseases such as malaria, yellow fever and others.

The idea of ​​the method is that mosquito larvae cannot penetrate the thin layer of oil on the surface of the water and die. To do this, special preparations containing oil are sprayed on the surface of the reservoir, or oil is simply poured directly onto the surface of the water.

However, despite the effectiveness of this method, it also has its drawbacks. First, oil on the surface of the water can prevent oxygen from reaching the water, which can kill fish and other aquatic life. In addition, oil can be hazardous to human and animal health if they come into contact with it.

Currently, the method of "oiling" reservoirs is rarely used, as there are safer and more effective methods of mosquito control, such as the use of insecticides or control bacteria. However, in some cases, when other control methods are ineffective, oiling can be used as an alternative method.

In conclusion, oiling water bodies can be an effective method of mosquito control, but it also has its disadvantages that must be considered when using it. In any case, the use of this method should only be carried out with special permissions and control from the competent authorities and experts.
