Distribution

edit

It shows nearly a cosmopolitan distribution throughout the Old World, except African continent both through human influences and natural methods. It is found in India, Sri Lanka[2] Malaysia, Thailand, New Guinea, Fiji Islands, Philippines, Rotuma Island.[3]

Importance

edit

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.[4] They prefer to consume eggs and larva Aedes aegypti and Anopheles stephensi.[5][6]

Alphamethrin, deltamethrin, Malathion can be used to control the mosquito.[7]
