Abstract
Two overproduced esterases (A8 and B8) notpreviously described were found in southern China. Theyprovide a low resistance level to organophosphate (OP)insecticides, and correspond to a coamplification of both esterase loci (Est-2 and Est-3)classically involved in OP resistance for this mosquitospecies. This coamplification is distinct from all othersimilar events thus far reported. The peculiar situation in southern China, where numerous OP resistancealleles at these two loci were found, is discussed incomparison with the Mediterranean situation, the onlyone with a similar diversity of overproducedesterases.
