MOSQUITO MANAGEMENT

MOSQUITO MANAGEMENT

These principles are describes in the evaluation of IPM programs, which is important to ensure their efficacy in reducing mosquito populations and mitigating human health risks.

IPM was initiated to overcome the shortfalls associated with indiscriminate application of pesticides application of pesticides. Pesticides application alone is not effective in controlling mosquito populations because it is difficult to get the pesticide into the habitat of the mosquitoes due to weather conditions or change in adult mosquito activity.

In addition, most pesticides used for adult mosquitoes do not provide long term residual control. Mosquito larvae are left continue their development, and will quickly replace adults. In fact, mosquitoes can build resistance if pesticides are overused.

MOSQUITO PROOFING MEASURES

3 Types of treatment carried as per the infestation/area of mosquitoes

1. Biological
2. Environmental
3. Chemical

1. Biological:

          Larvivorous fish (Gambusia) and Bacillus thuringlenisis (Vectobac)

2. Environmental:

          Properly seal septic tanks, vent pipes, overhead water tanks etc

          Discourage stagnation of water in any form

          Do not store water in any open container more than a week

          Avoid pipeline leakages

3. Chemical

Larvicidal Treatment

• Mosquitoes breed in stagnant water such as clogged storm water drains, septic tanks and other water stagnant areas.
• Suitable larvicide is applied on the surface of the stagnant water depending upon type of water that is cleaned or dirty water.
• Chemical – Penthion, Themephos 50% EC &Bti

ADULTICIDING TREATMENT

INDOOR RESIDUAL TREATMENT (IRS)

• Mosquitoes present inside the building are controlled by treating wall surfaces in the corridors, ceilings, staircase with odorless spray.
• Misting is carried out for control of adult mosquitoes with mist blower in common areas and vegetation side.

Thermal Fogging

• Thermal fogging is the effective method to keep away the adult mosquitoes.
• Fogging is carried out during dusk hours in immediate surroundings of the building to control adult mosquitoes.
• Chemical name: Kingfog

Adulticidal Chemicals

• Pyrethrum 2% and Deltamethrin 1.25 ULV
• Deltamethrin 2.5% SC and Bifentrin 2.5% EC
• LamdaCyhalothrin 10% wp and cyfluthrin 10% wp
