Insecticide bioassay dose-response curves for P. australiana (dotted line) and P. xylostella (dashed line) field strains collected from Angle Vale and Urrbrae, South Australia, and a susceptible P. xylostella (S) reference strain (solid line), exposed to four commercial insecticides: Dominex, Coragen, Proclaim and Success Neo. Points are the mean observed response across 4 bioassay replicates of 10 larvae each and lines are the fitted log-logistic response curves with 95% confidence intervals shown in grey shading. The vertical red line represents the approximate commercial field dose for each insecticide and vertical black lines represent the estimated LC99 for the corresponding Plutella strain
