Co‐occurrence and distribution of East (L1014S) and West (L1014F) <scp>A</scp>frican knock‐down resistance in <i><scp>A</scp>nopheles gambiae sensu lato</i> population of <scp>T</scp>anzania

The observed co-occurrence of L1014S and L1014F mutations coupled with reports of insecticide resistance in the country suggest that pyrethroid resistance is becoming a widespread phenomenon among our malaria vector populations. The presence of L1014F mutation in this East African mosquito population indicates the spreading of this gene across Africa. The potential operational implications of these findings on malaria control need further exploration.
