Table 6. LT₅₀ values from fumigation bioassay of methyl benzoate (MB) against Bemisia tabaci adults for different concentrations (n = 90).

MB concentration (%)	LT50 (h)	95% CI+ (lower- upper)	Slope (± SE)	χ2 (df)
1.0	5.0a	(2.4–8.5)	3.5 (0.9)	26.1 (3)
0.5	7.2b	(6.5–8.2)	2.6 (0.3)	2.1 (3)
0.25	11.2c	(9.3–15.1)	2.0 (0.3)	1.4 (3)
0.1	16.3d	(12.5–26.8)	2.0 (0.3)	1.5 (3)

⁺Confidence interval.

The LT₅₀ value was calculated using corrected mortality. LT₅₀ values followed by different letters are significantly different (95% CI) across MB concentrations
