Many species of mosquitoes are vectors of diseases, so important in medicine and other fields. [1] Well over 3,500 species of mosquitoes were found and described, and new species are about to discover. [2] Sri Lanka is home to 131 species of mosquitoes that included to 16 genera with 17 endemic species. [3] [4]

In 2017, Sri Lanka experienced its largest outbreak of dengue fever, a neglected tropical disease, since the first recorded case in 1962. [3] [4] [5] This biological hazard, transmitted via female mosquito bites, resulted in 186,101 dengue cases, a significant increase compared to previous years (see table below), and let to 440 deaths.
The large expansion is may be due to naval transport of larva from one place to another. In 1934, these mosquitoes were introduced to Fiji as a method of biological control of Aedes polynesiensis, and in India and Malaysia to control Aedes aegypti and Aedes albopictus who are prominent vectors of many human diseases.

A mosquito's period of feeding is often undetected; the bite only becomes apparent because of the immune reaction it provokes. When a mosquito bites a human, it injects saliva and anti-coagulants. With the initial bite to an individual, there is no reaction, but with subsequent bites, the body's immune system develops antibodies. The bites ...
