Mosquitoes are responsible for causing so many sever diseases like malaria, dengue, chikunguniya with which world is fighting with great efforts, they are causing more damage to human health day by day and human filling effort less. The World Health Organization is also trying to control this situation but they also don’t get satisfactory output, the patients of malaria, chikun guniya are increasing in large numbers.
The anopheles stephensi species of mosquito is responsible for causing the malaria disease. The anopheles Stephensi breeds in stagnant water like water tanks, overhear tanks, rain water collected in tarpaulin, tyers & water wells.
Diseases caused by different species of mosquito :
Anopheles Stephensi - Malaria
Culex - Filariasis, Japanese Encephalitis
Aedes - Chikun Guniya, Dengue
The treatment is divided in two parts :
● Larval Management (ANTI-LARVAL TREATMENT)
The mosquito growth is through 4 instars - egg, larva, pupa & adult. Larval stage is the weakest stage in mosquito life cycle & it is easy to control by spraying the breeding places thoroughly by using suitable Larvicide. The water collected area & all water bodies present at the site are sprayed thoroughly by hand compression spray. The larval stage is completed in 4 to 10 days so it is necessary to treat the water bodies on weekly interval.
● Adult Management (RESIDUAL SPRAYING)
The spraying will be done by using chemical having residual effect. All possible resting places of mosquito like labour hutments, garbage area, toilet, bathroom, darken places, ducts, gutter line, garden area etc; are treated by spray thoroughly.
FOGGING : The fogging will be done by using fogger machine. The ultra low volume form chemical is used which is mixed in diesel. Fogging is done at the time of dusk hours as the frequency of mosquito is high at that time.
