From: Fumigant toxicity and phytochemical analysis of Petiveria alliacea (Linneaus) leaf and root bark oil on adult Culex quinquefasciatus

Oil extract	LC₅₀ (ml)	95% confidence limit		LC₉₀ (ml)	95% confidence limit		Slope	χ²
Oil extract	LC₅₀ (ml)	LCL	UCL	LC₉₀ (ml)	LCL	UCL	Slope	χ²
Leaf	0.45	0.199	0.678	2.20	1.797	2.760	1.853	4.811
Root	0.53	0.301	0.714	1.43	1.194	1.695	2.991	6.232
Root and leaf	0.47	0.205	0.664	1.15	0.909	1.379	3.318	1.248

Lc₅₀ lethal concentration that kills 50% of the exposed adult, Lc₉₀ lethal concentration that kills 90% of the exposed adult, LCL lower confidence Limit, UCL upper confidence limit, Slope, χ² chi-square
