Fig 2. Mortality rates (means ± SD) of larvae per test vessel.

Larvae were exposed to either thiacloprid solely, a mixture of thiacloprid and 300 mg/L nano-Al₂O₃, or a mixture of 1000 mg/L nano-Al₂O_3, after 96 h of exposure (n = 12). Four comparisons (Likelihood ratio test and Fishers exact test, if necessary) were conducted (one for each thiacloprid concentration) and significant differences between the data displayed at the respective two ends of the horizontal lines are given (* p ≤ α when adjusted according to Holm-Bonferroni’s method [23], Fishers exact test). Nominal values are shown in this graph, whereas measured concentrations can be obtained from Table 1.
