Amino-acid substitutions in acetylcholinesterase 1 involved in insecticide resistance in mosquitoes

Résumé

n natural populations of mosquitoes, high level of resistance to carbamates (CX) and organophosphates (OP) is provided by insensitive acetylcholinesterase (AChE1). Different alleles conferring resistance have been identified at the ace 1 locus. They differ from the wildtype by only one amino-acid Substitution. The comparison of the biochemical characteristics of mutated recombinant proteins and AChE1 in resistant mosquito extracts confirmed the role of each substitution in insensitivity. Selection of these different resistant alleles in field populations depends likely on the insecticides used locally. Theoretical modelling studies are initiated to develop novel strategies of mosquito control. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
