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 selection pressure. In cases of multiple resistance, these dynamics will also
depend on how individual resistance mutations interact with one another, and on the xenobiotics applied against them. We compared
Culex quinquefasciatus mosquitoes harbouring two resistance alleles ace-1
R
and Kdr
R
(conferring resistance to carbamate and pyrethroid insecticides, respectively) to mosquitoes bearing only one of the alleles,
or neither allele. Comparisons were made in environments where both, only one, or neither type of insecticide was present. |
