Abstract

This chapter outlines the chemical methods for the control of ticks on cattle, and then discusses the evolution of resistance to acaricides, the effects of resistance on the use of acaricides, and the future of chemical methods for the control of ticks on cattle.

Abstract

The cattle tick Boophilus microplus causes significant economic losses in cattle in the tropical areas of Central and South America. Acaricides are widely used to control tick infestations, with the consequent selection of tolerant and resistant subpopulations. Detoxifying enzymes, and esterases in ...

Abstract

Selection pressure with the acaricide, amitraz was applied to a strain of Rhipicephalus (Boophilus) microplus (Canestrini) in 13 out of 18 generations, resulting in a 28.7-fold increase in resistance, indicating a shift in the phenotypic composition of the ticks, from a heterogenous mixture of both ...

Abstract

From 1907 when the fever tick eradication campaign began until 1933, the tick eradication methods of dipping cattle in an acaricide or "pasture vacation" were enormously successful in eradicating southern cattle ticks [Rhipicephalus (Boophilus) microplus (Canestrini)], until failures began to occur ...

Abstract

The efficacy of injectable doramectin applied at 200 µg/kg was evaluated against adult female Boophilus microplus (Canestrini) (Acari: Ixodidae) in the later stages of engorgement before detachment. Lethal levels of doramectin in the serum of treated cattle (9.7-36.6 ppb) were reached and sustained ...

Abstract

Toward the end of the nineteenth century a complex of problems related to ticks and tickborne diseases of cattle created a demand for methods to control ticks and reduce losses of cattle. The discovery and use of arsenical solutions in dipping vats for treating cattle to protect them against ticks...

Abstract

Acaricide resistance is a major problem that hinders the control of the tropical cattle tick, Rhipicephalus (Boophilus) microplus (Canestrini), in many parts of the world where cattle production continues to suffer severe economic losses to tick infestation. Deltamethrin and amitraz have been used...

Abstract

The efficacies of pour-on formulations of 3 macrocyclic lactone endectocides (moxidectin (Cydectin), ivermectin (Ivomec) and eprinomectin (Eprinex)) were evaluated on cattle against Boophilus microplus using 2 different treatment regimes. A single application treatment regime with each endectocide...

Abstract

The efficacy of an injectable microsphere formulation of ivermectin for control of B. annulatus was tested on 2 groups of 6 Hereford heifers held on separate 7-ha, tick-infested pastures in Texas, USA. Cattle in one pasture were injected subcutaneously in the neck with a controlled-release...

Abstract

The strategies available for the control of ticks on cattle in areas of the world other than Africa are reviewed with particular reference to Boophilus microplus and B. annulatus. There are 3 main sections, as follows: management options (chemical methods, host resistance and host management...
