Statistical differences between LC50 values were determined using the presence or absence of overlap in the 95% fiducial limits

50] values (in days), 95% fiducial limits
(FL), and regression slopes were estimated by probit analysis (Finney 1971) using POLO PLUS software for Windows (LeOra software 2007).
at 95% interval were used for differentiation of significance levels (Litchfield and Wilcoxon, 1949).
The LC50 and LT50 values and their 95% fiducial limits
were calculated from probit analysis (Finney, 1971) using Minitab(r) 15 computer software.

Significant differences among LC50 and LT50 values were inferred by non overlapping of 95% fiducial limits
