treated bed nets for everyone!

according to this document (Panamá) the best tools are :

Sprayed

in-home (IRS)

Mosquito nets

treated with

insecticides

http://www.usaidami.org/extras/PPT/44_SOD_Panama.pdf

and this other African document likewise recommends the same indication

The number of deaths caused by this disease in Africa has been reduced by half thanks to interventions aimed at controlling vector mosquitoes that transmit it such as LLIN and fumigation of closed spaces with residual insecticides (IRS ).

Among various vector control tool weather its insecticide based (i.e., IRS, ITN/LLIN, Fumigation) or any other tools like natural/ biological, environmental, social etc. used for malaria vector control, all proves to be an ideal and successful for that......only at single condition that vector population mustn't have developed tolerance/ resistance against it.....!!!!

Development of Resistance among vector population is something smashing all the  strategies for an effective vector control.

Long lasting insecticidal nets ( LLIN) 

Indoor residual spraying ( IRS)

I think the best vector tool is the one that is most effective to combat vectors in a certain geographic region that minimizes the development of resistance.  In some areas and for some vectors, one vector tool may be better or worse than for another vector in another region.  It depends on many factors, all of which need to be considered before taking action.  Other factors, including economics and others, need to be considered too.

Malaria control has to be two pronged-one tragetting malaria parasite and one targetting vector mosquitoes. Antimalarias are used to control malaria parasite in humans while vector control measures are targetted against mosquitoes. There can be many approaches for vector mosquito control, namely, indoor residual spray, insecticide treated bed nets, biological control measures, genetic control of mosquitoes. All approaches have their own advantages and disadvantages and a judicious mix is required based on vector biology and behaviour. However, Indian  National Vector Borne Diseases Control Programme mostly rely on indoor residual spray and Insecticide treated mosquito nets

I think the bbest tool is botanical based insecticides and plantation of botanicals with potentiality of controlling malaria vector as vectors seldom develop resistance/tolerance to plannt based insecticides.Working on phytochemistry of plant based insecticides and formulation of plant based based insecticides is a thurst for this emerging concerns.
