Researchers from Ifakara Health Institute and partner institutions have confirmed that the World Health Organization (WHO)’s standard testing method for treated mosquito bed-nets is consistent and reproducible across locations, mosquito strains, and laboratories.

The WHO standard testing method, technically known as “cone bioassay,” is used internationally to assess the bio-efficacy of insecticide treated nets or surfaces treated with insecticide formulations used in indoor residual spraying.

Results of the study, which confirmed the standard testing method, was published on the BMC Malaria Journal recently bearing the title: “Comparison of cone bioassay estimates at two laboratories with different Anopheles mosquitoes for quality assurance of pyrethroid insecticide-treated nets.”

Experiments for the study were conducted at the Ifakara Health Institute involving researchers from the Vector Control Product Testing Unit (VCPTU) in Bagamoyo, Tanzania. Other experiments were done at the Vector-borne Diseases Unit (VBDU) of the Papua New Guinea’s Institute of Medical Research (PNGIMR).

Also contributing to the study were researchers from PNGIMR, University of Basel and Swiss TPH in Switzerland, London School of Hygiene and Tropical Medicine in the UK, and Australian Institute of Tropical Health and Medicine in Australia.
