Notes: The mean mortality values results were expressed as mean ± SEM (three replicates) determined by via one way ANOVA followed by Duncan's New Multiple Range Test (DNMRT). The mean values, in the same column with different superscripts are significantly different P ≤ 0.05 while means with the same superscripts indicate non-significant changes. Abbreviation: ppm, part per million.
