Abstract:
The rotational use of insecticides with different modes of action for indoor residual spraying
(IRS) is recommended for improving malaria vector control and managing insecticide resistance
Therefore, a more diversified portfolio of IRS insecticides is required. Previous tests of propoxur,
bendiocarb & pirimiphos-methyl have indicated that residual activity is significantly
influencedby the wall surface. Inparticular, Bendiocarb showed poor residual lifespan on dung &
mud walls. The most commonly used surface in areas where IRS is conducted. An essential
component of IRS programs is insecticide resistance monitoring. The detection of resistance to
most existing insecticides underscores the urgent need for new insecticides with novel
chemistries, capable of delivering enhanced and prolonged control over insecticide-resistant
vector populations. Broflanilide is a newly discovered insecticide being considered for malaria
vector control.Thus objective of this study was to assess the efficacy of VECTRONTMT500by
sapling the insecticide formulation on different wall surfaces Throughout the nine-month hut
trial, monthly wall cone bioassay mortality on VECTRON T500 treated hut walls remained >
80%. IRS with broflanilide shows potential to significantly improve the control of malaria
transmitted by parathyroid-resistant mosquito vectors and could thus be a crucial addition to
determine its decay rates in Ethiopia
