Haemaphysalis longicornis, the cattle tick or bush tick, has an extended distribution throughout Asia and the Pacific region, including China, Russia, the Republic of Korea (ROK), Japan, Australia, New Zealand, and the South Pacific islands. It is an obligate ectoparasite found commonly on medium...

Many breeds of cattle with long histories of living in areas of endemic disease have evolved mechanisms that enable them to co-exist with specific pathogens. Understanding the genes that control tolerance and resistance could provide new strategies to improve the health and welfare of livestock....

Molecular tools based on seminested restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR) techniques were used to characterize field isolates of Theileria parva (collected between 1982 and 1997) in bloodspots dried on filter paper, to permit investigation of the extent and...

The basic structure and use of a general programme (TICK2) for modelling tick ecology and the epidemiology of tick-borne diseases is given. Its primary purpose is to serve as a framework in which to incorporate and test knowledge of the ecology of ticks and their livestock hosts. The model is...

The author reviews methods of monitoring the epidemiology of tick-borne diseases in livestock in Africa, primarily from the perspective of a model maker. The following subjects are discussed: the incidence and prevalence of tick-borne diseases in host populations, the sampling methods used to...

The author discusses the type of data required to model factors affecting the host-finding phase of ticks after moulting but prior to finding a host. Methods of interpreting data are given and there is a short review of field-data available for Rhipicephalus appendiculatus, Amblyomma variegatum, A. ...

The author discusses the type of ecological data required to model factors affecting the parasitic phase of ticks on livestock, such as the time spent on the host, the amount of blood ingested, the amount and type of foreign material introduced into the host (including tick-borne diseases) and the...

Information is given on the data required to use the T3HOST model to analyse control strategies for cost effective pest management of ticks, especially Rhipicephalus appendiculatus in Africa. The roles of host resistance, vaccination, dipping and animal density and movements are discussed.

Information is given on the use of the CLIMEX model in the management of ticks (Rhipicephalus appendiculatus, Boophilus microplus and Amblyomma variegatum) and tick-borne diseases in Africa, especially Kenya and Zambia. Its specific use in the analysis of the value of quarantine, the prediction of...

This paper is of interest inasmuch as the methods that have been employed for the eradication of the gross animal parasites in the United States are briefly reviewed and the possibilities of further success based on our present knowledge of the life histories of the parasites are discussed. The...
