Abstract

Considered as one of the most important arthropod pests of livestock, the exotic tick Rhipicephalus (Boophilus) microplus is invading Côte d’Ivoire and replacing the other species of the same genius, including the dominant species R. (B). decoloratus. It was reported in 2008 with 96 % of replacement in the southeast of Côte d’Ivoire, precisely in a radius of 50 km around Azaguié, the village from which R. (B.) microplus tick was first recorded. In order to better understand this phenomenon, a statistical model has been developed with software “R”. It stems from this study that the replacement of tick R (B) decoloratus by R (B) microplus is quick due. Estimates indicate for different levels of resistance, a period of 18 to 45 and 9 to 27 months was required for replacement of 100 and 96 % of R (B) decoloratus. Tick R. (B.) microplus could produce 3.3 times more offsprings than tick R. (B.) decoloratus and its increased resistance to acaricides could be a factor in the shortening of the period of replacement.
