*The asterisk (*) indicates a significant difference at (χ² test) comparing the responses actually observed in the bioassay to the regression line from the probit analysis. 1The RR is given as the values of LD50 of wild population/LD50 of laboratory strain to spinosad for the indicated post treatment time points. 2Within the LD column, different letters after the parentheses indicate significantly different LD50 values, as 95% FL did not overlap. |
