- The LD50 is expressed in µg AI test substance or µg formulation/bee.

- In case the LD50 is applied for the HQ calculation (see 8.4.2.), the LD50 of the AI should be used.

- Data should be summarised in tabular form, showing for each treatment group, as well as control and toxic standard groups, the number of bees used, mortality at each observation time, and number of bees with adverse behaviour (see Table 1).
