Bioassay analysis. Probit-transformed mortality rates as a function of the log-dose of insecticide [temephos (R), an OP insecticide]. Colors and point shapes indicate the different strains. The fit from the linear model is provided (solid line) along with the 95% confidence intervals (dotted lines). The linearity of the log-responses has been checked using test.validity = T in the “mort.plot” function from the “BioRssay” R package
