Abstract

Strategic dipping and pasture spelling plus dipping were compared in Queensland with no treatment on Droughtmaster cows and their progeny over 5 years. Average monthly counts of Boophilus microplus (Can.) on the young cattle and their dams were 10 and 18, <1 and 2, and 56 and 112, for the 3 treatments, respectively. There was stable transmission of Babesia bovis, B. bigemina and Anaplasma marginale to the progeny from the untreated cows. Strategic dipping, and pasture spelling plus dipping, seriously disrupted the transmission of B. bovis, and vaccination against this parasite is recommended. Pasture spelling plus dipping also interfered with the transmission of A. marginale and B. bigemina, but vaccination against A. marginale only is warranted. At 27-29 months of age, the young cattle in the strategic dipping group had...

Abstract

In an experiment in the Townsville area only small differences in the number of ticks counted on Droughtmaster and Hereford calves were noted, but the Herefords were treated to control tick infestations on four occasions during one year, while the Droughtmasters were never treated. No differences...

Abstract

Ten Droughtmaster and 9 Hereford cattle were born in an enzootic babesiosis area of Queensland and became naturally infected with Babesia bovis (argentina) and B. bigemina during a period of 3 years. They were then kept free of cattle ticks (Boophilus microplus (Can.)) for the remainder of an...

Abstract

A survey was carried out in areas of Queensland infested with Boophilus microplus (Can) in 1977-78 to ascertain what methods of tick control were being used by cattle producers and their attitudes to these methods. It was found that during the previous 6 years there has been a large increase in the ...

Abstract

The measures currently used for the control of Boophilus microplus (Can.) on beef and dairy cattle in Queensland are described and discussed on the basis of the literature. These measures are strategic dipping with acaricides, use of resistant cattle and vaccination against tick fever. Because of...

Abstract

The aims of the control programme against Boophilus microplus (Can.) in New South Wales are the prevention of introduction of ticks into New South Wales from Queensland, the prevention of the escape of ticks from the tick quarantine area (TQA) to tick-free areas of the state, the control of ticks...

Abstract

Integrated control strategies for Boophilus microplus (Can.) on Zebu X British cattle in southern Queensland are explored using computer modelling. A brief description of the tick population is followed by an investigation of the effectiveness of host resistance as a basis for tick control. Since...

Abstract

The situation regarding chemical control of Boophilus microplus (Can.) in Queensland and the problem of acaricide resistance is discussed on the basis of the literature and laboratory and field studies which demonstrated the potential of mixtures containing low concentrations of pyrethroids...

Abstract

Resistance to Boophilus microplus (Can.) was compared in Brahman (Bos indicus) and European (B. taurus) cattle in Queensland. Similar numbers of ticks matured on previously unexposed cattle of both species although development of larvae to engorged females was slower on Brahman than on European ...
