Louisa Messenger (Environmental and Occupational Health) co-published a paper on "Efficacy of Pyrethroid–Pyriproxyfen and Pyrethroid–Chlorfenapyr Long-Lasting Insecticidal Nets (LLINs) for the Control of Non-Anopheles Mosquitoes: Secondary Analysis from a Cluster Randomised Controlled Trial (cRCT)" in the journal Insects.
Failure to control nuisance mosquitoes may potentially affect adherence to vector control tools. In the present study, researchers examined the impact of two dual-active ingredient (a.i.) long lasting insecticidal nets (LLIN), namely Interceptor G2® LLIN (alpha-cypermethrin-chlorfenapyr LLIN) and Royal Guard® LLIN (alpha-cypermethrin-pyriproxyfen LLIN), on the density of Culex and Mansonia mosquito species as compared to Interceptor® LLIN (alpha-cypermethrin-only LLIN). These results suggest that the novel insecticides in the dual-a.i. LLINs did not have an additional impact on these species and that pyrethroids might still be effective on them.
