Mutations in the acetylcholinesterase (AChE) gene (ace-1) have been reported in temephos resistant insects (Fournier 2005) including the malaria vector Anopheles gambiae (Diptera: Culicidae) and the West Nile Virus vector Culex pipiens (Linnaeus, Diptera: Culicidae) (Weill et al. 2004b, Djogbénou et al. 2008, Tmimi et al. 2018). Here, ACHE is linked to malaria.
