(A) Geographical representation of collection sites in Cameroon. The study sites are represented by stars. The color represents the targeted species. (B) Susceptibility profile using WHO bioassay tube test according to the study sites. Mortality rates were recorded 24 h post-exposure to the discriminating concentration of insecticides. Data are shown as mean ± standard error. Mosquitoes were sampled both pirimiphos-methyl and malathion tests on the same day at Gounougou (December 2021) and Mibellon (October 2021)

PUBLICATION: Susceptibility profile of Anopheles and target site resistance mechanism against organophosphates in Cameroon, by Dr Judith Dandi & al.

News

Mosquitoes are becoming increasingly resistant to insecticides. As older insecticides such as pyrethroids become less effective, a different class of insecticides—organophosphates like pirimiphos-methyl (PM)—has been proposed as a possible alternative. This study investigated how mosquitoes in six regions of Cameroon respond to two organophosphates: PM and malathion. It focused on three major mosquito species: Anopheles…

Global Funds: Entomological investigations and stakeholder perspectives to support introduction of dual active ingredient ITNs into the wider vector control space

Projects

Randomised cluster control trials conducted in Benin and Tanzania provide compelling evidence of the epidemiological impact of using dual active ingredient insecticide-treated nets (dual AI ITNs) treated with chlorfenapyr (CFP) and alpha-cypermethrin in malaria control . The results of these trials indicate that the public health value of dual AI ITNs significantly exceeds that of…
