The Economic Impact of Cattle Tick Control in Central Africa

When two comparable herds of cattle were kept continuously in adjoining paddocks, frequent acaricidal treatment was necessary to control ticks (Boophilus microplus (Canestrini) ). Thereafter, one of the two herds was grazed alternately in its own and an adjacent paddock, the intervals between each transfer being sufficient to ensure that most of the ticks in the unoccupied paddock had died. Tick infestations on this herd were greatly reduced, and less frequent use of acaricides was necessary. The herd remaining in the continuously stocked pasture continued to need acaricidal treatment for recurring tick infestation. In a field trial with 350–400 cattle moved a t intervals to each of three formerly heavily infested paddocks, tick infestations remained very light, although the herd was dipped only In January, September, and the following January. A control herd on continuously stocked pasture, treated at the owner's discretion, required eight dippings in this period. This procedure of "pasture spelling" seems likely to be widely applicable in central Queensland.

Cattle Tick Control

A field study was made of the effects of γ BHC, Sevin, toxaphene and ronnel (fenchlorphos) used as sprays on the numbers of ticks infesting cattle at Shika stockfarm in the Northern Guinea Savannah zone of Nigeria.The tick population included Boophilus annulatus (Say), B. decoloratus (Koch), Amblyomma variegatum (F.), Hyalomma truncatum Koch and Rhipiccphalus simus simus Koch, and its distribution on the host is described.Significance tests of treatment difference were carried out for initial kill and reinfestation rate. In both dry- and wet-season trials toxaphene proved to be the most effective ixodicide. A satisfactory degree of control was given by γ BHC but not by Sevin or ronnel.It is concluded that spraying at 21- and 7-day intervals during the dry and wet seasons, respectively, with either toxaphene or γ BHC will maintain a stable, satisfactory level of tick parasitism and premunity to tick-borne diseases in the herd.
