Survival of IJs in five vegetable oil emulsions at concentration of 13%.

Survival of EPNs in oil emulsions of J. virginiana and C. citratus at a concentration of 13% under laboratory conditions.

Effectivity of EPNs at concentration of 50 IJs/tick in vegetable oil emulsions at concentration of 33% on engorged adult ticks. Bars with unequal letters are statistically different (Tukey, P ˂ 0.05).

Effectivity of EPNs at concentration of 100 IJs/tick in vegetable oil emulsions at concentration of 33% on engorged adult ticks. Bars with unequal letters are statistically different (Tukey, P ˂ 0.05).

Control effectiveness of S. websteri at 119 IJs/tick in two vegetable oil emulsions at a concentration of 33% and a Control with S. websteri in only distilled water.
