The subhumid and semi-arid zones of West Africa are one of the subregions reputed to hold Africa's greatest potential for expansion of animal agriculture. Within this region livestock are affected by tsetse-transmitted trypanosomosis-a disease that severely constrains productivity, thus hampering...

The exploitation of resistance traits very much relies on the understanding of the mechanisms underlying trypanotolerance, their characterisation in the field, the identification of practical measures of trypanotolerance characteristics, the evaluation of their linkage with final livestock output...

Parasite control and assessment of trypanotolerance
In the Philippines, management of grazing flock like rotational grazing is not being done as a parasite control, but to improve the condition of the pasture and the nutritional status of the animals. Posas (1981) compared goat production and impact of soil, pasture, and coconut production. Rotati...

In southwestern Ethiopia, recent chaotic events, changes in land tenure and introduction of tsetse fly [Glossina tachinoides] control have precipitated changes in the use of land and other natural resources. In turn, these changes have initiated shifts in rangeland biodiversity. Unexpectedly, sma...

For at least five decades, tsetse biologists have observed that the populations of some species of tsetse (particularly species in the morsitans group of flies) decline as fly habitat is converted into cultivated land and host populations are decimated by hunting. Some have even suggested that ts...

The hypothesis that HCN in cassava is a defence mechanism against arthropod pests is suggestive, but quality and quantity of empirical data is unsatisfactory and scarce. The burrowing bug (Cyrtomenus bergi Froeschner: Cydnidae: Hemiptera) is recorded as a major pest on cassava in the neo-tropics ...
