Bean Stem Maggot (BSM) is a serious production problem in many African countries. In South Africa, the problem receives very little research and extension attention. This study set out to assess the magnitude of the BSM problem at Greytown during the 1995 season. Using a split-plot trial, split f...

An expt. to study the background soil effects associated with var. resistance in bean pest populations, virus incidence and yield was carried out at the Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia from Jan.-March, 1978. The effect of the treatments and of the var. on Em...

Herd-to-herd variations in the primary biological impact of an intervention can sometimes be utilised to investigate secondary impacts. This approach has been used in the analysis of the effects of tsetse control on calf live weight gain. Nineteen herds of cattle were monitored in the region of B...

The use of baited traps and targets to control the tsetse fly has the potential for successful and sustainable trypanosomiasis control by local communities. However, with community-based programmes, community organisational capacity, incentives needed to initiate and sustain programmes, and intra...

Nineteen herds of cattle (N'Dama, Baoule and Zebu crosses) and 20 flocks of Djallonke and Djallonke x Sahel sheep in the region of Boundiali, northern Cote d'Ivoire, were monitored monthly for body weight, packed red blood cell volume and the presence of trypanosomes in blood over various periods...

Ticks and tickborne diseases (TTBD) are serious animal health constraints in Uganda and acaricides are the current method of choice for their control. Although widely used, the external-input, single-technology paradigm of chemical control is unsustainable and may inhibit endemic stability. TTB...

The economic and biological efficiency of cotton seed cake (CSC) and molasses urea block (MUB) supplementation to control gastrointestinal nematode parasites was examined in artificially infected Horro and Menz lambs from 3 to 12 months of age. The factorial O.xperimental design involved 2 breeds...
