Table 1 Definitions and abbreviations of the toxicological endpoints.
Variable | Abbreviation | Definition | Units | Model |
|---|---|---|---|---|
Concentration | C | Quantity of test product within the syrup provided as food to the bees | mg a.i./l syrup | |
Dose | D | Quantity of test product actually consumed by the living bees through their food (syrup) on a given day. The calculations were based on syrup consumption, concentration of the test product in the syrup, syrup density (1.23 g/ml) and the number of bees still alive | mg a.i. bee−1 day−1 | |
Daily Dietary Dose | DD | Average of the doses consumed during a given day and all preceding days | average mg a.i. bee−1 day−1 | |
Cumulative dose | CD | Sum of the doses consumed during a given day and all preceding days | total mg a.i. bee−1 | |
Lethal Time | LTx | Number of days of exposure to cause x% mortality at a given concentration | days | Based on the Weibull 2 model: Mortality vs Time |
Lethal Concentration | LCx | Concentration needed to cause x% mortality after a given period of exposure | mg a.i./l syrup | Based on the Weibull 2 model: Mortality vs Concentration |
Lethal Dietary Dose | LDDx | Average daily dose consumed per bee needed to cause x% mortality after a given period of exposure | average mg a.i. bee−1 day−1 | Based on the Weibull 2 model: Mortality vs Daily Dietary Dose |
Lethal Cumulative Dose | LCDx | Cumulative doses consumed per bee from day 0 needed to cause x% mortality | total mg a.i. bee−1 | Based on the Weibull 2 model: Mortality vs Cumulative Dose |
