Units (concentration causing 50% mortality) and (concentration causing 90% mortality) in units of g/mL. 95% confidence interval (CI) is shown in parenthesis. Insecticidal activity is considered significantly different when the 95% CI fail to overlap. Chi-square value of Probit model fit, all significant at level.
