a Dose-response curves for all species, b separated by sex for Leptopterna dolabrata, c separated by sex for Megaloceroea recticornis, and d separated by sex for Stenotus binotatus. Data points represent mean values per concentration, with error bars indicating the respective standard error for all concentrations greater than zero. Note that mean values for the lowest Mospilan®SG treatment for males and females of M. r. consist of only four replicates instead of six. Insect images © Gerhard Strauss, Biberach, Germany. Derived LD50 values are shown in the table below. Separate LD50 values for male and female specimens were generated only for those species where sensitivity to the insecticide was significantly different between the sexes based on the fitted generalised linear mixed model (GLMM). LD50 values were compared using the compParm function of the ‘drc’ package in R. LD50 values of species not sharing a common letter are significantly different. LD50 values of males and females of the same species not sharing a common letter are significantly different. CI confidence interval, N number of biological replicates (i.e. Petri dishes) per concentration.
