(trypanosomosis infection in cattle) is a major impediment to cattle
production and improvement in communal areas of Northern KwaZulu Natal.
Studies on the two species of tsetse flies vector capacity,
competence, and population dynamics have been initiated since 2005.
Tick-borne diseases and tsetse transmitted animal
trypanosomosis coexist in northern Kwa-Zulu Natal affecting the same population
of cattle. Parasitic ticks have been controlled for the past 100 years using
chemical acaricides in dip tanks. Currently, there is no tsetse control policy
in the country and no control measures have been implemented since1992. The
Government of South Africa is giving special attention to developmental
programmes targeting resource-poor farming societies. Creating tsetse-free areas
will bring a change in land-use benefiting these communities.
IPM and farmers participation strategy: The impact of the
control strategy on the incidence of tsetse-transmitted trypanosomes (locally
known as Nagana) and tick-borne diseases in cattle belonging to three
communities around the game reserve will help to anticipate the consequent
social and economic costs and benefits as well as sustainability of this pilot
project. Community participation will be a cornerstone in the implementation of
the project ensuring sustainable technology transfer.
The presence of reservoir hosts (game) of the causative
organism result in cattle becoming infected and re-infected with trypanosomes
after treatment with trypanocides, the development of drug resistance becoming
inevitable. Trypanosomosis considerably affects animal health and productivity
(62 % of infected cattle were anaemic and unproductive) and contributes to
poverty in the communities. The presence of reservoir host in game animals and
the interactions between tsetse/game/cattle considered as the main factors
determining the epidemiology of trypanosomosis are under study.
