Mosquitoes are one of the most important insects that transmit various types of communicable diseases such as malaria, Filaria, Japanese encephalitis, Dengue & Chikungunya. The common genuses of mosquitoes noticed are Anopheles, Culex and Aedes. These mosquitoes have specific breeding and resting preferences. Mosquitoes lay eggs in water and the aquatic stages of mosquitoes spends part of itís life (6-10 days) in water. Once the adult emerge out of water they would be in search of suitable host for blood feeding without which the mosquitoes cannot lay fertile eggs.
Due to increase in the open drains, dumping of plastics, improper disposal of broken consumer goods along with climatic warming supports the increase in mosquito population. Due to the increasing frequency of overseas travel, import of labour and decreasing effectiveness of both anti-malarial drugs against malaria parasites and insecticides against mosquitoes, the transmission of diseases like malaria, chikungunya etc cannot be avoided without controlling mosquitoes.
Hence elimination of mosquito breeding sources and modification of habitats along with reduction in the adult mosquito population is of primary importance for our healthy life.
The basic approaches to de-mosquito the population is elimination of breeding sites, elimination of larvae, elimination of adults, and deterring the insects from biting.
Mosquito larval stages depending on the genus develop in polluted stagnant water, potable water or water that stagnates in disused bottles, cans, plastic cups, gutters, rainwater butts, discarded tyres. Removal of rubbish obstructing the water flow in the drain channels can greatly reduce the numbers of urban mosquitoes.
A gentle smear of oil in the water surface of the drain channel reduces the population of mosquitoes.
However the regular usage of pesticides inside the residences is restricted as last line of action. Mosquito proofing along with common available vaporizers can be continued for reducing the adult mosquitoes.
A discussion with a professional in mosquito management is suggested.
