Properties Of A Factor In Eland Plasma That Inhibits Transformation Of Bloodstream-Form Trypanosoma Brucei Brucei, E. K. Nguu, E. O. Osir

All Peer-Reviewed Publications

Fresh plasma from the African eland, Taiirotragus oryx, contains a factor that inhibits the transformation of bloodstream-form Trypanosma bnicei bntcei into procyclic (midgut) forms. Heating of the plasma at 42, 50 and 60 °C for 30 min resulted in a 20, 38 and 40% loss of inhibitor activity respectively, whereas only negligible loss occurred below 42 C. Similarly, one and four freeze-thawing cycles resulted in 32 and 60% loss of activity respectively. Inactivation of the inhibitor activity, which occurred rapidly during storage (for example, 80% loss after 7 days at -20 °C) could not be stopped by the addition of …

Habitat Management Strategies For The Control Of Cereal Stemborers And Striga In Maize In Kenya, Z. R. Khan, J. A. Pickett, L. Wadhams, F. Muyekho Jan 2001

Habitat Management Strategies For The Control Of Cereal Stemborers And Striga In Maize In Kenya, Z. R. Khan, J. A. Pickett, L. Wadhams, F. Muyekho

All Peer-Reviewed Publications

Maize is the principal food and cash crop for millions of people in the predominantly mixed crop-livestock farming systems in Kenya. Stemborers and striga (Striga hermonthica) are major constraints to increased maize production in eastern Africa. An intercropping and trap crop system has been developed, using a ‘push-pull’ strategy, for the control of stemborers in small scale maize farming systems. The ‘push-pull’ strategy involves trapping stemborers on highly susceptible trap plants (pull) and driving them away from the crop using repellent intercrops (push). Napier grass (Pennisetum piirpiirenm Schumach) and Sudan grass (Sorghum vulgare sudanense Stapf J are used as trap …

The Chemical Ecology Of Host Location By Parasitoids Of African Stemborers, Linnet S. Gohole, Adele J. Ngi-Song Jan 2001

The Chemical Ecology Of Host Location By Parasitoids Of African Stemborers, Linnet S. Gohole, Adele J. Ngi-Song

All Peer-Reviewed Publications

During foraging, parasitoids of insect herbivores are aided by chemical compounds generally termed ‘infochemicals‘, to locate their hosts. The origin of the infochemicals varies; they may be derived from the herbivore itself or activities related to the biology of the herbivore, the host plant, or from interactions between the plant and the herbivore. This paper reviews the status of research in this area, and presents an account of the infochemicals used by African stemborer parasitoids during foraging, as well as recommending possible areas for further investigation. The information generated has potential for application in behaviour modification of parasitoids species in …

Effects Of Some Dietary Factors On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell Jan 2001

Effects Of Some Dietary Factors On Ruminal Microbial Protein Synthesis, M. Aki̇f Karsli, James R. Russell

Turkish Journal of Veterinary & Animal Sciences

The effects of some dietary factors, other than source and amount of N and carbohydrate, on the amount and efficiency of microbial protein synthesis are discussed in this review. Specifically, these factors include dry matter intake of animals, forage:concentrate ratio of diets, rate of N and carbohydrate degradation, synchronized release of N and energy from diets, rate of passage, and other factors, such as vitamins and minerals. It seemed that diets containing a mixture of forages and concentrates increase the efficiency of microbial protein synthesis because of an improved rumen environment for the growth of more diverse bacteria species.
