LT₃₀, LT₅₀ and LT₉₀ values of A. khorassanica and A. sieberi essential oils against the adult stage of S. cerealella

Essential oil	Concentration (µL/liter air)	χ2	Slope ± SE	Lethal times (h)
				LT30 (95% FL)	LT50 (95% FL)	LT90 (95% FL)
A. khorassanica	12	65.91	3.43 ± 0.42	6.34 (4.95–7.51)	9.01 (7.63–10.28)	21.29 (18.14–26.83)
A. sieberi	12	45.60	3.20 ± 0.47	9.24 (7.06–10.94)	14.37 (12.32–16.80)	42.28 (31.57–72.05)

Lethal times and 95% fiducial limits (FL) were estimated using logistic regression (SAS Institute 2002).
