The effect of pirimiphos-methyl on cultures of Acarus siro. A—Mortality of mites in the impregnated filter paper test. The lines are model fits (for parameters, see Table 1) and points of observed values; B—The comparison of mite final population density after 21 days of growth on control and pirimiphos-methyl residues (1.25 µg and 0.0125 µg). The data are shown as jitter box plots. The significant differences (Tukey`s pos hoc comparison for interaction) among the control and PM for same culture are indicated by Asterix
