Larval development test LD₅₀ ± SD
Mix1	266.6 ± 107.2	922.7 ± 232.1**
Mix2	826.4 ± 370.5	1256.5 ± 465.0**
Part B: In vivo	Numbers of adult worms
Mean number of adult worms ± SD	Infected animals	Infected animals with Mix1	Infected animals with Mix2
	1523 ± 187	1113 ± 274*	1327 ± 351

In vitro activity: data are means ± SDs of three independent assays with duplicate samples. Ovicidal and larvicidal activities are expressed as the concentration (μg/mL) of a median lethal dose (ED₅₀ and LD₅₀, respectively; the concentration of a methanolic or aqueous extract that prevents 50% of the eggs from hatching or larvae from developing to the infective L3 stage) using the egg hatch test or larval development test
In vivo activity: *Reduction of adult worms relative to infected animals 70 days after infection (P < 0.05)
**Means within a row are significantly different at P < 0.01
