their interaction with the insect-pest.
Hence, in an effort to increase the survival time and infectivity of EPNs on ticks, this study aimed to evaluate: (i) the effect of five vegetable oil emulsions on the survival and infectivity of S. carpocapsae, S. websteri and H. bacteriophora on ticks in laboratory and (ii) the control effectiveness (CE) of application of EPNs in oil emulsion on ticks present in infested dogs (Canis lupus familiaris) in field conditions.

, H. bacteriophora demonstrated low virulence on the pest larvae in petri tests with a LC50 = 426.92 IJ/larva. Hence, both Steinernema species were selected for subsequent experiments. The penetration rate for S. feltiae and S. carpocapsae into the hemocoel of the pest was 43% and 31%, respectively, and the corresponding reproduction rate was 15,452 IJ/larva for S. feltiae and 18,456 IJ/larva for S. carpocapsae. The gathered data from those in vitro tests were used for a field assay
