Popis: Individually tested Nile rats, Arvicanthis niloticus Desm., consistently preferred sorghum to wheat, groundnuts and standard laboratory food, and whole sorghum to cracked and ground sorghum. The addition of 5% sugar enhanced their consumption of sorghum bait. Similar results were obtained with groups of 2–4 animals in enclosures. Whole sorghum to which 2% by weight groundnut oil and 5% sugar had been added was preferred over all other foods. Small groups of rats in four enclosures were exposed to 0.18% zinc phosphide baits with either the normal cracked sorghum or the experimental whole sorghum‐oil‐sugar formulation. During pre‐baiting the rats consumed twice as much of the experimental bait as they did of the normal. During toxic baiting, however, consumption and mortality were similar for both baits. It is suggested that the experimental bait could be useful for attracting more rats to bait stations and that zinc phosphide may be effective at lower levels than usually applied for the control of...
