Do mosquitoes show resistance to PermaNet® 2.0?

The efficacy of PermaNet® 2.0 in areas where mosquitoes are resistant to pyrethroids varies depending on the type of resistance mechanism involved and the level of resistance in the mosquito population. In some areas, in particular where there is more than one resistance mechanism involved, there is a high probability that there will be a reduced efficacy with all pyrethroid treated nets, in which case a combination net such as PermaNet® 3.0 would be more suitable.
