Dose-efficacy response of azadirachtin in killing neonates of Diabrotica v. virgifera in artificial diet-based bioassays of 96-well plates under semi-sterile laboratory conditions. Corrected mortality shown, i.e. standardised for natural background mortality in the untreated control. Fluid neem product used (NeemAzal-T/S 10EC). 3 experiments as true replicates with Δ representing the mean values. 8 wells per treatment per each of 6 plates per each experiment. Trendline added of fitted logistic regression model: larval mortality (3d) = 1/(1 + exp(2.22 − 0.71 * ln(dose)) with confidence interval of the fitted line in grey
