Table 2. Toxicity of subfractions of fraction 3A against newborn (< 24 h old) Acyrthosiphon pisum nymphs following 24 h exposure to artificial diet containing different concentrations of the subfractions.
| Fractions | LC50 (95% CI) ppm | Ratio | LC90 (95% CI) ppm | Ratio | Slope ± SE | Chi-Square | HF |
|---|---|---|---|---|---|---|---|
| 3A-1 | - | - | - | - | 2.0 ± 1.3 | 4.9 | 0.4 |
| 3A-2 | - | - | - | - | 1.5 ± 1.2 | 6.6 | 0.5 |
| 3A-3 | 1 (0.6–1.6) | 1 | 14 (6.1–97) | 1 | 1.1± 0.3 | 14.8 | 1.1 |
Data is presented as lethal concentration values, 50% (LC50) and 90% (LC90) (both in ppm) together with their particular 95% confidence interval (95% CI), the slope ± SE of the toxicity vs concentration curve, and the Chi-Square and heterogeneity factor HF as accuracy of data fitting to probit analysis in POLO-PlusV2.
