Table 4. Toxicity of ethyl acetate and aqueous phase of acidic extraction against newborn (< 24 h old) Acyrthosiphon pisum nymphs following 24 h exposure to artificial diet containing different concentrations of both phases.
Fractions | LC50 (95% CI) ppm | Ratio | LC90 (95% CI) ppm | Ratio | Slope ± SE | Chi-Square | HF |
---|---|---|---|---|---|---|---|
Aqueous | - | - | - | - | 1.5 ± 1.2 | 6.6 | 0.5 |
Ethyl acetate | 0.2 (0.04–0.5) | 1 | 9.2 (3.9–13) | 1 | 0.8 ± 0.3 | 4.2 | 0.3 |
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.
