- Ace-1 duplication in Anopheles gambiae: a challenge for malaria controlLuc Djogbenou
Institut de Recherche pour le Developpement, UR 016, Cotonou, Benin
Malar J 8:70. 2009..This mutation entails a large fitness cost. However, a resistant duplicated allele of the gene encoding AChE1 (ace-1), potentially associated to a lower fitness cost, recently appeared in An. gambiae...
- Forty years of erratic insecticide resistance evolution in the mosquito Culex pipiensPierrick Labbé
Equipe Génétique de l Adaptation, Institut des Sciences de l Evolution, CNRS Universite Montpellier 2, Montpellier, France
PLoS Genet 3:e205. 2007..Instead, resistance evolution has been an erratic combination of mutation, positive selection, and the rearrangement of existing variation leading to complex genetic architecture...
- ProPhenolOxidase in Daphnia magna: cDNA sequencing and expression in relation to resistance to pathogensPierrick Labbé
University of Edinburgh, IEB, Ashworth Laboratory, Kings Buildings, Edinburgh, UK
Dev Comp Immunol 33:674-80. 2009..This is the first evidence of a Daphnia immune response, and our observations raise the possibility that the PhenolOxidase (PO) cascade is involved in the defence against pathogenic gram-positive bacteria...
- Resistance Gene Replacement in the mosquito Culex pipiens: fitness estimation from long-term cline seriesPierrick Labbé
Universite de Montpellier, Montpellier Cedex 4, France
Genetics 182:303-12. 2009..e., with a large fitness variance across environments). More generally, we discuss how precise estimates of the strength of selection obtained from field data help us understand the process of amelioration of adaptation...
- An ancient immunity gene duplication in Daphnia magna: RNA expression and sequence analysis of two nitric oxide synthase genesPierrick Labbé
University of Edinburgh, Institute of Evolutionary Biology, School of Biological Sciences, Ashworth Laboratory, Kings Buildings, Edinburgh, UK
Dev Comp Immunol 33:1000-10. 2009..Thus, the function of NOS in Daphnia immunity remains uncertain, but the pattern of gene duplication and subsequent divergence suggests evolution via neo- or subfunctionalization...

Insect Biochem Mol Biol 40:317-24. 2010..Rdl selection in these two mosquito species discloses current insecticide pressures in urban areas, from unknown origins, that should be taken into account to develop vector control strategies...
- Independent duplications of the acetylcholinesterase gene conferring insecticide resistance in the mosquito Culex pipiensPierrick Labbé
Institut des Sciences de l Evolution UMR CNRS 5554, University Montpellier II, Montpellier, France
Mol Biol Evol 24:1056-67. 2007..The rate of duplication of ace-1 in C. pipiens is probably underestimated, but seems to be rather high...
- Novel AChE inhibitors for sustainable insecticide resistance managementHaoues Alout
Universités Montpellier 2 et 1, Montpellier, France
PLoS ONE 7:e47125. 2012..This study identifies the first compound class that preferentially targets OP-resistant mosquitoes, thus restoring OP-susceptibility, which validates a new prospect of sustainable insecticide resistance management...
