Figure 1From: Patterns of phenoloxidase activity in insecticide resistant and susceptible mosquitoes differ between laboratory-selected and wild-caught individualsLevels of phenoloxidase activity (active PO and total PO) per microlitre of homogenate sample (mean ± se) in unsexed L4 larvae (dark symbols), and in male (grey symbols) and female (white symbols) adults of Culex pipiens mosquitoes. Adults were either 1-day old (A1), 7-days old (A7) or 14-days old (A14). Experiment 1: (a) active PO and (b) total PO in isogenic strain mosquitoes: insecticide-susceptible mosquitoes (SLAB strain, circles), esterase resistant mosquitoes (SA4B4 strain, triangles), acetylcholinesterase resistant mosquitoes (SR strain, squares). Experiment 2: (c) active PO in field-caught mosquitoes: insecticide-susceptible mosquitoes (S, circles), esterase resistant mosquitoes (E, triangles), acetylcholinesterase resistant mosquitoes (R, squares).Back to article page
