Costs and benefits of multiple resistance to insecticides for Culex quinquefasciatusmosquitoes (2008)

Berticat, Claire, Bonnet, Julien, Duchon, Stéphane, Agnew, Philip, Weill, Mylène, Corbel, Vincent

Abstract Background The evolutionary dynamics of xenobiotic resistance depends on how resistance mutations influence the fitness of their bearers, both in the presence and absence of xenobiotic...

Characterization of a Novel High-Activity Esterase in Tunisian Populations of the Mosquito Culex pipiens (2008)

Raja Ben Cheikh, Claire Berticat, Arnaud Berthomieu, Nicole Pasteur, Hassen Ben Cheikh, Mylène Weill

In the mosquito Culex pipiens (L.) (Diptera: Culicidae) esterases contribute to insecticide resistance by their increased activity. These esterases display a heterogeneous geographical distribution,...

Forty Years of Erratic Insecticide Resistance Evolution in the Mosquito Culex pipiens (2007)

Pierrick Labbé, Claire Berticat, Arnaud Berthomieu, Sandra Unal, Clothilde Bernard, Mylène Weill, ...

One view of adaptation is that it proceeds by the slow and steady accumulation of beneficial mutations with small effects. It is difficult to test this model, since in most cases the genetic basis of...

HIGH WOLBACHIA DENSITY CORRELATES WITH COST OF INFECTION FOR INSECTICIDE RESISTANT CULEX PIPIENS MOSQUITOES (2006)

Olivier Duron, Pierrick Labbé, Claire Berticat, François Rousset, Sylvain Guillot, Michel Raymond, ...

In the mosquito Culex pipiens, insecticide resistance genes alter many life-history traits and incur a fitness cost. Resistance to organophosphate insecticides involves two loci, with each locus...

PARASITISM INCREASES AND DECREASES THE COSTS OF INSECTICIDE RESISTANCE IN MOSQUITOES (2004)

Philip Agnew, Claire Berticat, Stéphanie Bedhomme, Christine Sidobre, Yannis Michalakis

Adaptations conferring resistance to xenobiotics (antibiotics, insecticides, herbicides, etc.) are often costly to the organism's fitness in the absence of the selecting agent. In such conditions,...

High Wolbachia density in insecticide-resistant mosquitoes.

Berticat, Claire, Rousset, François, Raymond, Michel, Berthomieu, Arnaud, Weill, Mylène

Wolbachia symbionts are responsible for various alterations in host reproduction. The effects of the host genome on endosymbiont levels have often been suggested, but rarely described. Here, we show...

Variability and Expression of Ankyrin Domain Genes in Wolbachia Variants Infecting the Mosquito Culex pipiens▿ †

Duron, Olivier, Boureux, Anthony, Echaubard, Pierre, Berthomieu, Arnaud, Berticat, Claire, Fort, Philippe, ...

Wolbachia strains are maternally inherited endosymbiotic bacteria that infect many arthropod species and have evolved several different ways of manipulating their hosts, the most frequent way being...

Acetylcholinesterase genes within the Diptera: takeover and loss in true flies

Huchard, Elise, Martinez, Michel, Alout, Haoues, Douzery, Emmanuel J.P, Lutfalla, Georges, Berthomieu, Arnaud, ...

It has recently been reported that the synaptic acetylcholinesterase (AChE) in mosquitoes is encoded by the ace-1 gene, distinct and divergent from the ace-2 gene, which performs this function in...

Forty Years of Erratic Insecticide Resistance Evolution in the Mosquito Culex pipiens

Labbé, Pierrick, Berticat, Claire, Berthomieu, Arnaud, Unal, Sandra, Bernard, Clothilde, Weill, Mylène, ...

One view of adaptation is that it proceeds by the slow and steady accumulation of beneficial mutations with small effects. It is difficult to test this model, since in most cases the genetic basis of...
