Project Description: New malaria vector control methods are urgently required to deliver distinct, complementary insecticide classes as mosaics, rotation or ideally, combinations more effectively and efficiently than long lasting insecticidal nets (LLINs) and Indoor Residual Spraying (IRS) do. Eave baffles (EBs) are simple housing modification using widely-available netting materials, which can be treated with existing insecticide formulations. Treated EBs and window screens trap mosquitoes to exit again. Liverpool School of Tropical Medicine (LSTM) AND Ifakara health Institute... New malaria vector control methods are urgently required to deliver distinct, complementary insecticide classes as mosaics, rotation or ideally, combinations more effectively and efficiently than long lasting insecticidal nets (LLINs) and Indoor Residual Spraying (IRS) do. Eave baffles (EBs) are simple housing modification using widely-available netting materials, which can be treated with existing insecticide formulations. Treated EBs and window screens trap mosquitoes to exit again. Liverpool School of Tropical Medicine (LSTM) AND Ifakara health Institute (IHI) recently collaborated to assess an experimental prototype of insecticide treated EBs, as an alternative to IRS for malaria vector control, in standardized experimental huts in southern Tanzania. Compared with IRS using the same insecticide, EBs killed similar proportions of Anopheles funestus that were resistant to phyetroids, carbamates and organochlorines and greater proportions of pyrethroid-resistant early exiting an Arabiensis.EBs treated with pirimiphos-methyl (PM) WERE EQUALLY efficacious when co-treated with binding agents (BA)s, EBs required ≥ 5 times less insecticide than IRS and co-treating with BAs could enhance durability, so they represent a more affordable and efficacious alternative to IRS.
