Susceptibility of ticks to acaricides in Zambia
Tropical Animal Health and Production, 1984The susceptibility of some Zambian ticks to dieldrin, dioxathion, dimethoate and chlorfenvinphos was determined on two- to three-week-old larvae of Amblyomma variegatum, Boophilus decoloratus, B. microplus, Rhipicephalus appendiculatus, R. e. evertsi and a member of the R. pravus group. Some strains of B. decoloratus and R.
