U. Zieger et al., THE EFFECT OF CHEMICAL TICK CONTROL ON CATTLE ON FREE-LIVING IXODID TICKS AND ON TICKS PARASITIC ON SYMPATRIC IMPALE IN THE CENTRAL PROVINCE, ZAMBIA, South African Journal of Wildlife Research, 28(1), 1998, pp. 10-15
Cattle on a mixed cattle and wildlife farm in the Central Province of
Zambia were regularly treated with acaricides. This resulted in a redu
ction in the abundance of certain free-living ixodid ticks on the vege
tation, and of ticks parasitic on sympatric impala Aepyceros melampus
when compared with a neighbouring ranch where only game is kept and no
chemical control is practised. The ticks most severely affected by ch
emical control were Amblyomma variegatum, Rhipicephalus appendiculatus
and Rhipicephalus evertsi evertsi, Boophilus decoloratus appeared to
be unaffected, possibly because of acaricidal resistance. Some tick co
ntrol measures on wildlife are discussed.
