Relation between the energy delivered to the adult female mites and observed mortality after irradiation at three different exposure times (60, 120, and 240 s) using the pulsed KrF excimer laser; the study was undertaken at 20–25 °C, in April 2018. Average mortality curve (thick black line; calculated using data for the entire exposure period) and corresponding confidence interval (light grey band). Parameter estimates for the four-parameter log-logistic regression model are as follows: slope − 2.22, lower limit 18.87, upper limit 99.69, median effective dose 14.60
