LC50 is lethal concentration required to kill half of number larval tested after 24 hours.
RR50 is resistance ratio at LC50 = LC50(resistant strain)/LC50(Kisumu).
Chi(p) is indicated to judge whether the data are well fitted to the regression or not. The fits are acceptable when the p-value is over 0.05.
