  1. Nr Number of tested larvae. The LC50 of probit analysis and the slopes of the probit lines are given. Cl 95% confidence interval; SE Standard error. LC50 value and confidence limits are given in OBs/ml. All Wald χ2 tests (DF = 1) were significant at P < 0.0001 according to Robertson and Preisler (1992) [29]
