The results indicated that the crude petroleum ether, hexane and methanol extracts of Adhatoda vasica were effective against Hyalomma anatolicum adults and petroleum ether extract was found the most potent with. lc50, 303.62 and lc90, 1030.23 ppm followed by hexane extract with lc50, 581.33 and lc90, 2069.52 ppm and methanol extract with lc50, 1247.85 and lc90, 3692.61 ppm after 24 h of treatment. estimated reproductive factor (erF) and % inhibition of egg laying were also assessed along with mortality response of tested concentrations of each extract. Hexane extract being the most effective among all the tested extracts showed 100% mortality at 2400 ppm and egg laying inhibition 78.88, 82.06, 88.02 99.13 and 99.67% at 400, 800, 1200, 1600 and 2000 ppm after 15 days of exposure, respectively.
