[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 the early 1970s two type of dengue dominated in Sri Lanka: DENV-1 type1 and DENV-2 type 2.
“There are thousands of species of mosquitoes, only a few of which transmit human pathogens, so if the disease-transmitting species were eliminated, non-disease-transmitting species would often ...
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.
Species E is sympatric with species B in southern Tamil Nadu and Sri Lanka. The distribution and proportion of sibling species is subject to change through varying seasons. For example, in Delhi, where species A and B are sympatric, species A is predominant throughout the year, but proportions of species B increased during post-monsoon months. [9]
