Figure 4.
AChE residual activity of C. pipiens larvae and of recombinant ace-1 proteins, (percentage of initial activity), for increasing concentrations of inhibitor (in mol l−1). Both larvae and recombinant proteins are from a susceptible reference strain (SLAB) and an insecticide resistant strain (SR). Six different inhibitors were tested: (a) propoxur, (b) trichlorfon, (c) malaoxon, (d) paraoxon, (e) aldicarb and (f) eserine. See §2 for details. Yellow, susceptible larvae; dark blue, resistant larvae; red, susceptible ace-1 recombinant protein; light blue, resistant ace-1 recombinant protein.
