Units LC₅₀ (concentration causing 50% mortality) and LC₉₀ (concentration causing 90% mortality) in units of μg/mL. 95% confidence interval (CI) is shown in parenthesis. Insecticidal activity is considered significantly different when the 95% CI fail to overlap. ^aChi-square value of Probit model fit, all significant at P < 0.05 level.
