12. Mosquito Control Measures
 Biolodical Method:-Use of Fish
 Guppy/ Gambusia / Bti /B- Sphericus etc.
 Source Reduction:-
 Elimination of reduction of breeding sites.
Filling up burrow pits,ditches,unused irrigation
cannals,wells,deweeding,chanalization etc.
 Personal Protection:-
 Use of Repellant
 Use of mosquito net.
 Application of Nylon mesh to doors and
windows.

13. Formula for measurement
of surface area of Bed net
 Surface Area =2 ( a + b ) +c
 where
 a=length x height
 b=height x width
 c=length x Width

15. Methods of Impregnation
 Prepare solution in optimum quality of water with
required quantity of insecticides.
 Soak bed net in solution thoroughly.
 Do not hang it, dry it by spreading on a rubber
sheet in a shed.
 Residual Efficacy:-6 months if not washed
 Precautions:-Avoid contamination of
skin,eyes,mouth with insecticide formulation.
 If contaminated ,wash with soap and water.

16. Impregnation of Bed nets
Quality of Bed nets
 Bednet hole size:-
 Not bigger than 1.2 to 1.5 mm. diameter
.i.e.6 to 8 holes to 10mm linear length.
 Dosage:-
 25 mg Deltamethrin/sq.mt.
 or
 50mg Cyfluthrin/sq.mt.
