Abstract.The residual repellent activity of N, N‐diethylphenyl‐acetamide (DEPA), N, N‐diethyl‐3–methyl benzamide (DEET) and dimethylphthalate (DMP) against the hard tickRhipicephalus sanguineus(Latreille) and the soft tickArgus persicus(Oken) from topical application on rabbits and hens respectively in the laboratory have been studied. It was found that a 25% concentration of DEET gave strong repellency (>90%) against larvae and nymphs ofR. sanguineusfor 15 and 7 days respectively and againstA.persicuslarvae and nymphs>90% for 11 and 5 days respectively. Strong repellency (>90%) against adults of the hard and soft ticks was observed for 9 and 7 days respectively with 40% DEET. DEPA at 25% concentration showed strong repellency (>90%) against larvae and nymphs ofR.sanguineusandA.persicusfor 11 and 5 days respectively. Adults of hard and soft ticks were strongly repelled (>90%) for 9 and 5 days respectively by 40% DEPA. DMP was found to be the least effective against all stages of both specie
