Studies on the Metabolism of Lactose, Melibiose, Sucrose and Raffinose by Erwin/a Chrysanthemi
(University of Fort Hare, 1995) Mabinya, Leonard Vuyani
One of the challenging problems for a bacterial cell is to detect chemical changes that constantly occur in its environment, and to regulate and integrate its metabolism in response to such changes. The primary function of many cellular activities in these organisms is directed towards this task.
These activities may include transport processes‚ cellular locomotion and chemotaxis, and the secretion of digestive enzymes (Saier, 1977; Dills et al.‚ 1980; Postma and Lengeler, 1985; Mitchell, 1985).
An Evaluation of the Oesophageal Fistula Valve Technique
(University of Fort Hare, 2000-05) Lebopa, Cornelia Kedidimetse
The oesophageal fistula valve technique (Raats & Clarke‚ 1992) was evaluated in terms of its ability to reflect the daily forage selection pattern of free ranging goats over a period ot four seasons and two Stocking rates. During the. evaluation, the oesophageal fistula valve technique was compared to the standard oesophageal fistula bag technique and observed feeding behaviour. Comparisons were in terms of: (i) proportion of grass or bush.(% DM) in both the fistula bag and valve samples compared against the time spent grazing or browsing i (% of active feeding period); (ii) the changes in chemical composition (CP, NDF, ADF and ADL) of the bag samples versus that of valve samples and; (iii) diurnal changes in feeding behaviour and plant species selection pattern of free-ranging goats based on observations.
Efficacy of the Diamondback Moth Parasitoid Cotesia Pletellae and Farmers' Perceptions About the Pest
(University of Fort Hare, 1999-12) Leutley, Mamogoto Frans
The diamondback moth (DBM), Plutella xylostella (L), is the most destructive pest of cabbage and other cruciferous crop's world wide (Mitchel, Tingle, Navasero-Warde & Kehat, 1997). It is a holometabolous pest which survive as long as 50 days at low temperatures and as short as 15 days at high temperature (Hutchison, Bolin, & Hines, 1997). The main method of control practiced by farmers has been the use of synthetic insecticides. Due to over- dependence on chemicals, several pesticide related problems such as resistance development, hazards to non-target organism, environmental pollution, poisoning and residues in crops have surfaced and become serious (Lim, Loke, Chan & Syed, 1988). The alternative strategy to manage this pest would have to involve biological control as major component of the integrated pest management. The latter approach requires the study of this pest and its natural enemies.
