| Abstract: | A method whereby resistance data can be analysed by means of frequency distributions is described. This method established that Rhipicephalus appendiculatus and R. evertsi evertsi show either little or only developing resistance to the pesticides chlorfenvinphos and dioxathion. Boophilus spp., however, show more instances and higher levels of resistance to these 2 pesticides. |
