Since 2011, period of the livestock invasion by the cattle tick  Rhipicephalus microplus  in Burkina Faso (BF), tick-control problems were exacerbated. Based on farmer’s reports, most commonly used commercial acaricides were found to be ineffective in Western South part of the country. To investigate the occurrence and extent of such acaricidal ineffectiveness, we performed the standardized larval packet test (LPT) with commercial deltamethrin (vectocid) and cypermethrin (cypertop), on two cattle tick species, the native  Amblyomma variegatum  and the invasive  R. microplus . The resistance ratios (RR) were computed with susceptible Hounde strain of  Rhipicephalus geigyi  as reference. The  R. microplus  population showed resistance to the two acaricides tested with the highest lethal concentration (LC) values, and different resistance ratios higher than 4 (deltamethrin: RR 50  = 28.18 and RR 90  = 32.41; cypermethrin: RR 50  = 8.79 and RR 90  = 23.15). In the contrary,  A. variegatum  population was found to be highly susceptible to acaricides tested with low lethal concentrations and resistance ratio values (deltamethrin: RR 50  = 0.5 and RR 90  = 0.48; cypermethrin: RR 50  = 0.68 and RR 90  = 0.79). These data demonstrate high synthetic pyrethroid resistance in  R. microplus  strain, leading to conclude that the acaricide ineffectiveness in tick populations control remains a concern in BF.
